Horrible job....glad my video helped and brought amusement 👍

It's a beautiful job 🙈 🤪 but at least you now have heat in the car ......one job I never want to do again 😂

Yeah it's a bitch....took me 6 hours. Getting the pipes back together is the horrible part

Also took me 6 hours....not a fun job but nice to have a hot car again. Yes when the battery is disconnected the steering has to be re calibrated to turn the lights off.

@@whatsdavedone104 VW were wanting £1200 to change. I managed to get a quote from a VW specialist - they wanted £950. My new matrix was £120, £10 for new coolant and £10 for an long extension socket and radio removal keys. So glad I attempted this myself. A used a garden kneeling cushion to help my knees. A few cuts on hands but the £900+ saved outweighs this! Cheers again Dave. Brilliant video - which made me laugh also. 👍😂

@djneilhaines VW and VW specialist would remove the full dash, that's why they quote so high, they don't really want the job. Glad it's save you a lot of money and gave you a laugh 😃

@@djneilhaineshow did you flush your system out. And when you flushed it did you flush it whilst the old matrix was inside or when the new one was installed. Any other tips I’ve got all the parts just need to change it now

@@hpls8160 Didn’t flush. The coolant looked to be okay, so I risked it. 2 months later my car is still roasting on my daily commute. I will drop the coolant when I have a nice day in spring.

I have pain in my right shoulder for about a week after....getting the clamps back on the pipes took far to long 😫

It's a b@@ch of a job....vw charge £1800 as its supposed to be a full dash out job 🙈 give yourself a good 6 hours

It's a absolute b@@ch of a job....probably easier/quicker to pull an engine🤣....Full dash out if you go to VW....but you did it 👌

@mtnick How did you fare out with the seals. I only have the orange o rings with my matrix. Did you put in the black seals as well?

Awful job, VW/audi charge around £1800 as its a full dash out job for them. There was no chance of flushing mine, it was solid 🙈

Horrible job to do 🙈 so glad the video helped you

@@whatsdavedone104 it is.

Yes both sets of seals need to go in. Yes it's a pig of a job....for VW to do it its around £800 as they take the full dash out 🙈

Yes it's a b@@ch of a job....but you did it. Yeah sound like how long it took me

Hi Dave what was the make of the matrix that you used as a replacement thanks

Not sure/can't remember 🤷 got it from my local independent parts place.

Yeah it's supposed to be a whole dash out job on the Golfs also 🙄

Pain in the arse of a job 🤣

Dread to think what they would charge...according to VW its a full dash out job 🙄

Raising and lowering but not going above 90⁰ ? That's your thermostat that's stuck open....nothing to do with heater matrix

@@whatsdavedone104 raising and lowering above 90. Raising so high at times it goes into safe mode and have next to no power. Car itself isn’t overheating. New timing belt done, water pump replaced. Still doing it. Read a few forums where thermostats etc have been changed and still same problem persists. Someone bypassed the heater matrix and problem went away. Think I’m more hopeful it is the heater matrix than anything else as problem is rather annoying.

@alpina2335 this is something new to me 🤷‍♂️ never heard of a bad matrix causing over heating but when my matrix failed it was winter time so might be different in summer.....let me know how it goes 😉

@@whatsdavedone104 yeah it’s a real strange one. As I said I’ve only managed to find two forums with same problem and apparently they changed this and seemed to get rid of the problem. Very strange one, I can drive round the town and will sit bang on 90. Soon as I go to work (25 miles) it starts rising. Then falling to 90, then rising, then….. you get the picture. But I’ve never been able to pinpoint what causes it. Is it driving after a certain time, hitting a certain speed, something I’m doing in the car, I have no idea. I just hope this clears the problem. But I will let you know how I get on. Thanks again.

@alpina2335 I would start by bypassing the matrix, just add a bit of pipe....run hose pipe into matrix and see if it flows

It's a shitty job lining the clamps back up 😒 I dread to think what a mechanic would charge. Glad I did it and it didn't leak. Mrs now complaining that car is to hot 🤣

🤦‍♂️🤣🤣

B☆☆☆h of a job though 🤣

Please let me know how much they charge, would like to know how much I saved by doing it myself 😉

@@whatsdavedone104 will let you know.

$3500 🤮 full dash out I guess

Day 3 🙈 makes me feel better that it only took me 6 hours....dread to think what VW would charge as they say its a full dash out job....keep going you will get there.

Sounds like block matrix to me....here is a link to a similar ratchet as mine amzn.to/3G0RYS0

Yeah thats what i thought🙈😆 So thats gonna be some shits and fucks this week🙈😆 Thnx for the link🙏🏻

No, even if you drain the coolant there will still be a little in pipes to the matrix....remember to top it up when finished.

I lost approximately 300ml of coolant. Not really worth draining the coolant. My coolant was changed back in the summer, but if you haven't changed coolant in last 2 year it's probably best to drop it all and put fresh in after replacing the matrix

@what's dave done 300ml is not too bad. Changed coolant a couple of months ago, so a relief I don't have to flush it again. Thanks mate.

Remember once you change the matrix to have heating on full heat and strength to get any air out of the system before topping up....I didn't and just had to drive 10 miles to my Mrs as the coolant light was flashing, she was panicking 🤣

I was effing and blinding....but I never, well once or twice, swear in my KZfaq videos....its a bitch to get the clamps back on 😖 not a job I would do again in a hurry 😤

It was an aftermarket heater core, it was gummed up it rust and sediment, which over time became compacted.

thank you for the most kind reply. Do you think it would have been any easier and quicker with original part heater core?@@whatsdavedone104

@colin5064 no, I think it would have taken just as long, reconnecting the pipes was the most time consuming part, as no room for 2 fingers let alone 2 hands to hold them in place.

So were you working on a 2010 1.6 tdi?@@whatsdavedone104

Yes Golf, bora, jetta etc from 2004 all the way through to present day have exactly the same set up

B@@ch of a job 🙈

I ordered from my local independent car parts centre, didn't have it in stock but was delivered 4 hours after ordering. Yes came with all seals

Ordered the same matrix last week but it only came with the orange seals. I contacted Nissens (the manufacturer) and they told me to just use the orange o rings. Take off the black seals….. this would make sense I suppose as the o ring’s are not present in the original one, looking at your video. What do you think Dave? Could this explain why it was so hard to get the pipes to line up again? If that’s the case why were they supplied with yours🤷🏻‍♂️

@GaeilInisCeithlean yeah maybe they are not required 🤷‍♂️ will it make it easier, possibly, but it's still going to be tight as not much movement between pipes and matrix

I used both seals, didn't use O ring at first and it leaked....yes it's a massive struggle to get the pipe connected 🙈🙈

@@whatsdavedone104 yeah not the o ring but the other seal just seems to roll up/fold when you try to push it together😂

If I remember correctly I ousted it up the pipe a little then pushed it in with the help of screw driver....its not a fun job 🙈

@@whatsdavedone104 yeah I’m gonna put the seals in some hot water for a bit I think😂 there’s just too much movement to clamp them together haha

@danielking5749 good luck 🙈 definitely nit a job I would want to do again in a hurry

It's a bitch of a job....it took me 6 hours 3 hours of that was getting the pipes reconnect, once I had them connected it was leaking and had to re connect them again as I hadn't put O rings in place. Might have been easier with a second set of hands

@@whatsdavedone104 i’ve gotta do it in one day on my own. I feel confident but it’s just gonna be a bitch🤣 anything you would’ve done different? Thanks for the reply

@simpsonvaletingservices4177 it would have been quicker had I not have been filming. Anything different, yeah make sure the clamps are sitting exactly how there were when you remove them, one points up, one points down and make sure you top up your coolant when done. I forgot then had a phone call from my Mrs saying "there's lights on on the dash" and had to drive 30 mins to put 400ml of coolant in....its been grand ever since 😀

@@whatsdavedone104 good but bad sort of news🤣 ill grab some coolant, cheers mate!

@simpsonvaletingservices4177 and remove your interior light fuse so the battery doesn't go flat.

Can you see the heater flaps moving when you operate the dials? Could be an air lock in the heater matrix 🤔 open expansion tank, turn heaters on full and let it get up to temperature. I had to put about 500ml of coolant in after changing mine....didn't add that bit into the video

@@whatsdavedone104 where is the expansion tank m8

The globe shaped bottle that you fill with coolant to the max line

I had to make few amendments to the plastic cover...seems that the aftermarket ones are not quite the same as the oem ones they use from factory....just broke of bits of plastic until it fitted correctly

Okay thank you. He got it back for now it will do. He just putting it all back together the glove box and that. Too cold for all this shit 😂

@Carley Woodham it's a horrible job to do, has it been checked for leaks🙈

@Carley Woodham and top up the coolant, think I added about 500 ml.....after I forgot a few thr coolant light came on 🤣

No, even if you drain the coolant there would still be coolant in the matrix when you remove it....just remember to top the coolant back up to replace what's lost when removing.

I’ve just been trying to put the new core in now but I’ve had to leave it for the night otherwise I’d smash the car up I’m that p*ssed off with it. I did the heater core on my wife’s 14 plate A3 and that was really easy. Back to the golf it’s strange how the old matrix doesn’t have seals in the core itself, only the ones on the pipes.

@matthewking5193 yep it's a b@@ch of a job, I nearly gave up when doing mine but had no choice. Sleep on it and start again fresh tomorrow.....good luck

I’ve been using my pry bar to help squeeze them together. I’ve done one but I’m not sure if it’s clamped it all round because of course ya can’t see

@matthewking5193 try getting a little mirror down the back to see if on 🤷‍♂️

My guess would be heater matrix is so blocked the the coolant isn't cycling the system.

@@whatsdavedone104 thanks dave, just done my thermostat today (very difficult job) but heater still not working and too much pressure in coolant tank

Definitely a blockage somewhere, no heat would point to heater matrix

@@whatsdavedone104 thanks Dave, appreciate ur help

More likely an issue with heater matrix than the radiator, It's probably starting to block, only heating at top and remains cold at bottom due to blockage

my golf VI cold air comes out on the passenger side and normal air comes out on the passenger side, I tried to run a diagnosis and everything turned out fine, the motors and probes are fine, can the internal passenger compartment radiator be used? mine is dual zone thanks touching the radiator pipes makes the inlet and outlet hot

@umbertoditrani7119 maybe your HVAC needs reset 🤔 kzfaq.info/get/bejne/gbCYlK9nmq6waYU.htmlsi=4Y_-wCFr1xNN1auO

@@whatsdavedone104 Calibration already done doesn't change anything you suspect that it's the internal passenger compartment radiator which is halfway blocked I don't have to dismantle it and check I can't understand anything anymore

@umbertoditrani7119 there is only one heater matrix, no separate heater for each side

I'm in pain...can't lift my right arm from the angles it was at. Really not a fun job. Now my Mrs is moaning that the car is too hot 🤣
