Test the vacuum pump directly. There's a vacuum pump testing video in my list.

Hello. Can you give me a lot more information please? Are you losing coolant? Is the engine overheating? The cooling system has many, joins, pipes, seals and gaskets.

@@sirobb hi the engin is constantly 90c… it is not losing cookant

The coolant level is going down when I drive…. when I open the coolant tank and the pressure goes down from the pipes. It fills up between Max and min

@@MuBe-um7rq Check the coolant level when the engine is stone cold. It must be at maximum on a cold engine. It does not matter if the coolant level changes with engine running as long as there is no coolant loss and no overheating. From your description, I can't see a problem with your cooling system. I have a cooling system flushing video in my list if you still think you have a problem. Never open a hot cooling system.

@@sirobb why do the pipes get that hard ( the pipes after the thermostat)or is that normal ? Again thank you a lot for your respond.

Google Volvo Vida 2014d

There's no other button in this video. Not sure about other models, sorry.

@@sirobb The button inside by the park break that releases the door lock when you refuel. XC90 T6

@@VauveAnais If that's the main fuel flap release button, you'll still need to use it. This video is just for the hinge on the fuel flap. Separate from the locking mechanism.

@@sirobb Thank you

What is the "wet"? Oil? Diesel? Water?

@@sirobb i would say its either oil or water because i wont smell the typcial diesel smell in cabain neither when the engine in running and iam right above the injector

I also have to say that is has 300.000km and 22 years on the engine. No start problems no uneven idle no nothing. Besides a popping in oil filler cap but i did everything u showed for vaccum leaks. Guess its the pump itsself then.

@@gldkrne1312 Thanks for the extra information. First, your car should contain oil, screenwash, coolant, hydraulic fluids only. There should be no clear water as such in your car anyway so if it is water, it's from an external source (rainwater, splashes up from the road) so no issue. I would tackle this problem like almost every other problem in life from above and below. If it's from above, the most likely is worn pipe or connection from the leak back pipes coming from all 5 injectors leading back to the HP Pump. The leak may not be from directly above number 5 but could be tracking there from the left or right so thoroughly dry everything and maybe use some talcum powder or French chalk in the area which will give away moisture if the source is above. If the injector sealing washer is only slightly breached, you'd be unlikely to see a bubbling up from below as the engine is only idling and fuel pressure is around 5000 psi. Thoroughly dry the area take the car at higher engine speeds therefore raising fuel pressure to 20k+ psi. Now that amount of pressure being introduced into the cylinder could easily be making its way back up the injector if the seal isn't 100%. There can be small amounts of oil in the cylinder forced up from the sump which could be further forced up. With all this said, if engine data and performance is ok, correcting a minor leak may not be worthwhile. Finally, consider all intercooler/boost connections as a leak there can create an oil mist in the vicinity.

@@gldkrne1312 My vacuum pump is leaking too. Bearable and performance is ok so a job for the future.

Glad it helped. The beauty of a lot of these alternators is that the individual components can be changed or cleaned up without wholesale replacement of the alternator. The brush pack/regulator, slip rings, rectifier and pulley can all be replaced for considerably less.

@@sirobb this video seems to show normal RH threads ? kzfaq.info/get/bejne/oJOCddySvNnRo2g.htmlsi=CeD4va0CSKS7QZRl&t=842

I don't know. You can build up jacking height with blocks of wood on the jack saddle or stand the jack on a raised service. Never get under any raised vehicle though unless *you* can be sure of *your* safety.

Sure. What would you like to know?

@@sirobb hi ive tried a couple of places now what say they repair the cem units and they have said they dont have the components for my Volvo v70 which is a 2001 d5 ive tried Volvo diagnostics aswell ive been advised by a mechanic that its the cem at fault as its clicking noises from relays when trying to start it ive replaced new starter all new earth wires new battery had all relays and fuses checked and wires just atca total loss now and dont want to have to part with the car if i can help it many thanks for getting back to me

Volvo diagnostics volvodiagnostic.com/central-electronic-modules/69-early-p2-platform-remanufactured-cem-xc90-v70-s80-xc70.html have a Cloning service so you get a working CEM with the same part number and they transfer your original data onto the "new" CEM You can pick up used CEM on eBay for £20 to £100 depending on timing but the part number match to your exact CEM is essential. They also on occasion have a refurbished CEM in stock so they can clone your details that way. Pricing varies. I cannot recommend the service highly enough. If you look for your own, see the attached photo link. Hope that helps. flic.kr/p/2pSVomW

Yea they do fail, all the time

I used to do this on my Dad’s Maxi when I was a kid and it was having solenoid trouble. Couple of clumps with the rubber handle of a hammer and it would start right up.

The Maxi starter design used to mash the teeth on the flywheel too. Sometimes we would have to put the car in gear and physically rock the car to budge the flywheel to a section with working teeth for the starter to engage. All within a couple of years from brand new. 70s British engineering. 😊

@@sirobb Thank you. Do you think the procedure applies to the TF-80SD as well?

@@christianbdk503 I have no idea. Sorry.

@@sirobb All good, thanks. I will perform it on the 80SD and report here.

?

@@sirobb I've placed an online order for the same brand of seal as used in the video. That description was part of the specification

@@p--n Corteco are superb so just match the part number and the spec will be automatically correct. Less research required.

@@sirobb information from the SKF website - These have either a right-hand twist for shafts that rotate clockwise, or a left-hand twist for shafts that rotate counter-clockwise as seen from the air side

@@p--n I used the Volvo main dealer software for my parts diagram and the part number is the same both sides. That's obviously for my exact car configuration though so yours *may* be different.

How I do it takes a few hours so you probably wouldn't want to pay for that. Most garages will do a drain and fill change which is good enough for about £50. It's an easy cooling system to work on.

If it's actually stripping the threads, yes but I doubt that's happening. Sometimes I need a plumber's wrench to tighten sufficiently to be airtight. Perhaps a little silicone spray on the threads to smooth the way.

Still running fine all these years later. Don't know what you saw but nothing is wrong.

This is a Euro 3 so as long as the class is matched, no further coding required.

@@sirobb so can I take injectors out a 2002 s60 and put them in 2010 xc90 and thank you for reply

@@johnmcguinness7116 Different injectors so not compatible in any way. 2010 is Euro 4 so may need coding. 2010 is a bit new for my speciality.

Any regular *penetrating* fluid. Brands like Plus Gas and WD40 but check it's the penetrating version not just lubricant.

Still going great thank you Kieran and I hope your fleet are too.

​@@sirobbstill got mine although I don't use it much nowadays I must get it out and drive it today. Everyone tells me to sell it. I like it Rob they are good cars. They won't make cars like those volvos again. Im glad you keeping well and youre s60 is going strong

You're welcome. 👍🏾

Gern geschehen

Amazing guy

I still have my s60 I feel for it it sits there undriven for weeks.life has got mad in my middle age 😂. Im the only one who loves it 😮😢.

No, different part numbers as shown in the video.

But they're look alike. What is the difference?

Euro 3
