I have to say it for everyone... this should be title "The Holy Grail" video's of all Fiat 500😊 thank you and outstanding video!!!!

Living in Europe and i can confirm that multiair was indeed used in Fiat cars...not for long though (only 4 years from 2009 till 2013)... I got a Fiat Punto from 2012 with the 135 bhp 1.4 turbo multiair that works great as of today and never failed me so far. I love it ! 😊

Thank you. That's the best explanation of timing this motor that I have found on the internet. You sir are a gentleman and a scholar.

Found your channel first via one of your Fiat videos but stayed for the nerdy airplane content. Great content Greg, thanks for the entertainment and stay safe everyone.

Thanks for uploading these videos! I've had my 500 Abarth for 7 years now and just now starting to tune her. Almost at 100k miles so I'd like to tear her down and rebuild to make more power!

Another fabulous video on this engine. Brilliant, loved the engine tour. Thank you

Great video, thank you! At the oil pump are two threaded plugs. I put oil temp and oil pressure sensors there (with adapters).

Really enjoyed your videos on this engine rebuild..thank you for taking time to make it and post it!!!

Very informational video! My timing belt tension blew out and I jumped time but the engine seems to be okay, gonna tackle it this coming weekend!

Was kinda stretchy getting into fiats as a next car but this video definitely put me on the buy side. Thanks for your time into this video

Thank you for the great explanation of the Multiair engine!

This is one knowledgeable man. Thanks Ive an Abarth 124. Love it.

GREAT Job, Again Greg!

I have that engine in my 2013 Dodge Dart. It's a fun engine for sure!

Thanks Greg. Looks like it's going well. Be careful trying to install it by yourself, some things go better (and safer) with extra hands to help. I'm anxious to see the finished item in action. It would be cool to see that Abarth 500 in action too. Cheers

I like that you speak in the same way as with the planes, but I nothing about cars vs planes. Thanks for the info.

Thank you so much for the the incredible video ! What a great amount of valuable information for these motors I have a jeep renegade with this motor . The worst part is now I need to find one of these Motors so I can build one for the jeep

Very informative Greg. Nice job. Thank you.

Outstanding tour of the engine! Thanks

Lovely piece of work.

just found your channel, i love your 500!

It looks like a staked nut on the belt tensioner which would make sense how it holds together. It still seems a bit light on backup plans but obviously works.

Thanks for sharing the build videos.

TY TY TY!!!! I run a 2013 Abarth with 50hp wet nos kit.... Just picked up 2 used motors to build....

That steel coolant pipe under the exhaust manifold with the funny nut goes right back to the the original 1980s Fiat FIRE engine. They work well but on older cars they are noted for corrosion. Worth a coat of paint (on top of OEM) in my opinion.

This engine certainly merits a tour especially since FIAT gets bagged a lot.

Great video, I have the 1.4L engine in my 2016 500X POP with a 6-speed manual, it's a fun car.I don't plan on any mods but I love learning about it.

Great video. You’ve enlightened me big time, as I also have a 124 spider. Thanks Greg

So I was at this Jeep Service Station in India and they didnt know how to lock the camshaft for timing belt change. But thanks to you!

Greg is the man!

Great video..Thanks!

Greg, after watching this you have me thinking about doing that C&B cam.

The oil cooler is a plate type heat exchanger. The idea was perfected by Rolls Royce with patents going back to the 1970s but it's likely they had them even longer ago on classified equipment.

what are the figures for torquing down the multi air system? thanks

Thanks for the great content! Ending up here looking for info on the 1.4 multi air tear down. I have a possible bad head gasket. Were is the best place to get a good manual? Thanks

I wish I had access to E85 where I live, due to the laws here changing fuel and doing a remap are pretty much the only things I can do to legally alter the performance of my car. Thanks for the video, have been very interested in the 124 roadster and hunting for an Abarth right now.

Well Done!!!

Hi Greg like the vids , was wondering what wheels you have on your 500 Abarth . Tks

Old Fiat FIRE engines (1.1L especially) are popular in Eastern Europe for amator racing - slap in 1.2 head, factory 4-2-1 exhaust manifold, 42mm throttle body or ITBs from a 650cc bike, balance rotating assembly, put flywheel on a diet and you'll get around 120HP reving up to 8500 - 9k RPM

Enjoyed the video, amazing tour. You mentioned to use the right oil, I live in Arizona , temps here in the summer ave 108+ F 🥵. Can you suggest a couple of good oils for this engine. Thank you .

Me again. The 1.6, 1.8 and 2.0 twin can engine as used in certain Fiat cars and the Alfa Romeo TS (Twin Spark) had non-keyed cam pulleys. Cam locking tools sat over cam lobes on each cam. You also needed a reaction (holding) tool to hold the cam wheel while torquing the retaining bolt.

Hi Greg, compliments for your video, i have a question regarding the manual you are using in the video can you help me with a link. Best Regards Roger

I, too, have the 1.4L MultiAir in my 2013 Dodge Dart. Love the car, love the performance. Unfortunately, at 100K miles I had to get the top of the engine rebuilt. The cam lobes were completely worn down leaving the MultiAir system without enough oil pressure to work properly. Have you ever had that happen to one of your engines? Most of my mileage was highway, commuting to work five days a week, 160 miles round trip. Not especially hard driving, but I did use manual shift mode frequently with the 6-speed DCT and always used spec oil.

Awesome Content! Thank you so much for your time and effort! I have a 1.4 non turbo. How hard is it to change the valve stem seals on this engine? I'm getting oil smoke out of the exhaust, it isn't a pcv leak and spark plug wells are dry from the top. The car smokes in the morning as the oil accumulates over night in low temps and burns off on first igition, again, not condensation or coolant. Am wondering if it's doable to use a valve spring compressor and patiently replace the valve stem seals before winter hits.

were do a buy the no namer tool is it on ebay ? thanks

how can I rebuild my engine like that is there a place I could send and get quality parts?

great Vid! what type of motor mounts will you be using?

Thank you

Hi greg… thank you for the videos. I have a question I hope you can answer. I have read in a couple different fiat forums that I need to lock out the camshaft first and rotate the crankshaft to align the tool. Your video says to do the opposite. Which one is correct? I am working on a US version fiat 500 Abarth. Is the t-jet engine a different process and that’s why those guys are saying the manual calls for the camshaft to be locked first? I don’t get why it would be different but that’s what they are saying.

Greg, How much torque is on the timing belt tensioner nut? And is 88lbs correct for the cam nut?

multi air is in the 2.4L Tigershark variant in JEEP Cherokees. I thought they should have used an electric oil pump because the mutliair if it sits for extended periods has a longer crank time until the oil pressure pumps back up.

German fiat fan here. Despite a lot of BS, talked about FIAT, they always build very good an inovative engines. The rest of the cars, can be discussed.....

Greg, Would you be able to do a timing belt/water pump service video on the 1.4 Multiair?

I have a 2017 with 50,000 miles. Can I really wait for 15 years or 150,000 miles before changing the belt?

Hi Greg. What is the torque spec for the flywheel bolts on the Fiat 500? I can’t find it and I figure you would know. Love your videos btw. Thanks

Hey Greg nice vids, very helpfull! I wonder hows the status right now. It would be very cool to show how engine is getting changed. Maybe you could make a vid with the cat bolt on to see how much space is there fo a custom exhaust manifold;) anyway thank you for this series, greetings from switzerland

Thanks 🙏

Greg, what an excellent video and so informative. Thank you. Can you tell us your thoughts on the multiair spring "upgrade" that gets so much talk? The one I have heard of is offered by a company named Tork motorsports. Thank you, Greg.

Need Help This may be a dumb question. I can get to the head bolts to remove the head. 1.4 multi air. I took out the 8 short bolts. But they look to short for head bolts. I think the head is 2 pieces? But can't get the spark plugs tubes to give.I am doing something totally wrong. The manifold turbo off the intake still on. Anyway can't get head to move or can't find the head bolts. Thanks

I wouldn't take the engine out to change the timing belt. However, I got stuck when removing the first cast. It is connected to the compressor support casting.

I did a timing belt and water pump on a 2013 fiat abarth turbo in the car u talk about a tight fit

Any input on troubleshooting a MultiAir actuator without specialized equipment? I have a misfire on Cyl 4, new plugs, no help. Move coils, missfire does not follow. Exhaust stinks like fuel, I'm certain It's getting it. Next step is a compression test. From what i can tell, these solenoids fail closed, so no compression would mean failed actuator (or worse...) right? Also any input on finding good used or overhauled units? I'm hesitant to put a $1000 actuator on what's realistically a $3500 car... 2012 500 Sport N/A.

I have the same engine. Been experiencing some power loss on my Giulietta 1.4 TB, checked the boost solenoid and cleaned it, I also checked the tubings around it if there were any leaks. My wastegate actuator isn't moving and stays in place, and the bars aren't increasing, might have to check if there is any boost leak, do u think that's the problem? and thanks

Thanks for your informative video. how about turbo problems, since there were some claims about it in Europe, especially versions before 2018.

Anyone know if the timing belt kit is the same for T jet and Multiair?

Is the Garret turbo charger made by the same company that builds turbine engines for MU-2s and twin Commanders?

I'm guessing that cam positioning tool is very difficult/impossible to put in position when the engine is in situ? If so, is it a case of Tippex'ing your own timing marks when changing the timing belt?

Do you think that gearboxes from the other cars that use the 1.4 T-jet Motor can also work on the bravo?

Where is the diverter valve hooked up? I see the blow off gauge on the turbo, but I was under the impression the diverter had an electronic connection.

I was told the timing tensioner needed to be adjusted to full tension first then rotate shaft twice then adjusted to center, is that correct? Or will it be ok to just adjust to center notch.

Greg, could you list the timing tools in the description?

I wish I had the knowledge and the patience to do stuff like this on my own time, it legitimately looks fun. And I must ask, is that your Jeep in the background?

Can you weigh in on the use of stiffer multi-air springs? You were talking about the fact that you could prove that modified multi-air units fail and cause valve to piston contact. There are is a tunner that uses stiffer multi-air springs in his stage 2 package. Claims better pull through the upper rpm range.

What water injection kit would you recommend? Thanks.

is the procedure same for Fiat tjet 1.4 16V ?? Also, are those tools 100% necessary or other ways timing can be done by a , say, a reasonably experienced mechanic ??

So the tool kit is not just for keeping the correct timing in place, but also setting the correct timing? Or am I understanding the use of the timing tool kit wrong?

Greg, do you know somebody who is competent to rebuild this motor in Los Angeles area? Abarth 500 1.4 MultiAir turbo ("EAF" motor). And also what is the rough cost? Appreciate it

Fuel vapor harvester sounds really interesting.

How much did this motor cost to build?

greetings,i own a fiat 500 sport none turbo with 98000 miles on it.I've done all maintenance on this car and often wounder how long do these multi air engines last?

Greg, is it possible to convert the belt to chain?

Great explanatory video ! Thank you ⭐️⭐️⭐️ I have an Abarth 124 1.4 multi air from new with 40000 Km now. My recent mechanic ( official FIAT dealer ) has been using the 10W50 oil for my car on last 3 services and I drove about 14.000 Km with that oil…. I was assuming there were using the recommended oil as per manual ! Previous services with another garage , were using the recommended 5W40 . I don’t get why the FIAT dealer is using the 10W50 for ALL Abarth’s not taking in account if it’s a multiair or a T-jet !! I told them about and they are not bothered. I have changed garage and replaced for the 5W40. My question is , do you think I have damaged my engine by using the 10W50 for 14.000 Km ?

Hello Greg. I have a 2019 500L that I'm wanting to do minimal upgrades to for a little extra pep/mileage. I'm having an incredibly difficult time finding an air intake for this model. Could you please point me in the right direction?

What prompted the rebuild? Looks like a good candidate for a motor swap or just swap in a salvage yard motor and save a small fortune?

Evening Greg! Thanks for such a detailed video. How hard would you say changing both belts and the water pump would be with a couple of jack stands and the correct timing tools in my driveway? I'm a sparks by trade and have some practical knowledge and have just purchased a 2015, 75k "1.4 Multiair TB Alfa Romeo Gulietta QV-Line" and it doesn't show this being done in the service history so thought I could tackle it, saving some money, gaining some exsperiance and the peace of mind knowing it wasn't attempted with sharpie marks by a garage. Is this the correct order of operation: 1) Remove the battery and the air Intake (to make room around the vacuum pump). 2) Jack the bottom of the engine to unload it slightly and place a jackstand for support. Where is a good place to put the jack stand and the jack to prevent cracking the case? 3) Remove the engine mount, freeing the area around the belts. 4) Remove tension on the serpentine belt and then remove it from the crank pulley. 5) Remove the crank pulley and install the locking tool by rotating the crank until the tool aligns with the bolt post before tightening it in place. 6) Remove the vacuum pump and install the holding plate (I assume that it will align correctly first try now as the crank is already locked in the correct position?). 7) Remove the tensioner and the timing belt and loosen the cam sprocket (Whilst holding tension on the cam sprocket with an external tool to prevent snapping the cam rod). 8) Remove the water pump with a container below to capture any excess coolant (I assume I don't need to drain the coolant reservoir or the radiator to do this? / This isn't going to all come rushing out?). 9) Install a new water pump with a bead of liquid gasket around the perimeter after cleaning the mounting services with a plastic scraper. 10) Install the new timing belt and tensioner, over-tensioning it slightly past the mark to allow for the tensioner to spring back, at this point the cam sprocket will also rotate slightly taking up slack in the new timing belt? 11) Torque down the cam sprocket (Whilst holding tension on the cam sprocket with an external tool to prevent snapping the cam rod). 12) Remove both timing tools and turn the engine manually twice and then check the tension is still correct. Am i listening for strange noises? weird grinding? how will I know if it's wrong? 13) If the tension is still correct reinstall other components, remove the jack stand and jack , and after waiting a little while for the battery to charge the system (To not upset the Alfa ecu) start the engine. I hope this all correct? If i go to install the holding plate and it doesn't align (Even though the crank is locked it the correct position) what do I do? does that mean the engines timing is slightly off in this hypothetical scenario? (even though the engine runs fine at the moment). Correcting me and any extra advice would be so much appreciated Greg, I hope to hear from you soon!

Sorry for the off-topic but will you ever make a vid on the Thunderscreech? That plane is weird and fascinating and there isn't much in-depth info online apart from how loud it was.

Hi, I have a 124 spider and over the weekend when I got my oil changed, my mechanic said I need a new water pump and thermostat. Will this require the engine to be taken out? Or can it be worked on withouthout have to remove it?

Do you reccomended mopar oil only?

Hey Greg hope you can answer a question for me. While I was priming the brick on my 1.4 engine through the ball valve under the oil filler cap the ball went missing where did it go and is this a problem.

Hey Greg, I know this comment doesn’t belong on this video but is there a possibility you can do a video on the HE-177? The paired engine drive system is fascinating and I have no idea how they achieved it.

Hi can you help me or direct find a manual 6 speed gearbox for my 2009 fiat Bravo 2 198 1.4 T-jet I have the selespeed 6 semi automatic system and it has failed I am doing a conversion instead of replacing the selespeed gearbox and having the same problem with the electrical

Not sure but seems you removed AC. Is there a kit? I have a 1.4 none turbo i dont need the AC on

Hi Greg, it's been 4 weeks since you last uploaded anything. Just wanted to make sure everything is fine.

Hello Sir, greetings from Nottingham in England, thanks for the very imformative video, i currentley own a new Jeep Renegade with the exact same engine, my question to you is, if it is at all possible to change the timing belt by just using the locking tool on the cranckshaft only? without having to remove the vacum pump on the other side of the enginein orther to lock the camshaft aswell? if providing i make sure the camshft pulley does not move at all, and make a fine mark on the cranckshaft pulley and camshaft pulley, is it possible to turn this engine through two full turns by hand on completion? or will it cause damage to the multiair system? please advise me as currently this video appears to be the only accurate one available on the net, or anywhere indeed. Thank you so much for you help.

Are you installing this in an old 124 or a new one?

Can I ask one favor?? Can you please share with us what spark plugs are best for this motor ?? And if you want , the plugs for your modified engine vs the ones we would normally use?? It would be greatly appreciated!!!

I’m trying unsuccessfully to remove the crankshaft sprocket/timing gear. Could you please confirm that the threading is normal for removal (counter-clockwise)? Thank you.

The Jeep engine is a completely new series of engine itroduced in 2016 called the Hirricane. Have not worked one one but it was supposedly developed in house by Alpha for the Giulia

I've got a 2017 Lusso, should I really let the belt go to 150K? A lot of people seem to scoff at that number.

Awesome video! Enjoyed everything except the blow off valve... not a fan of that piontless sound. LOL
