DaveDorson Posted September 25, 2018 Share Posted September 25, 2018 Has anyone done one of these? Do I really need VAG Com if I lock all the pulleys in the same place as they were in before I took the old belt off? Seems a bit bloody silly. Surely if it's not lost timing, and everything is locked in place, it's still timed correctly with the new belt installed? Also, is it REALLY a 5 hour job to do with the water pump too? I remember doing a Mk2 golf cam belt in about 38 minutes before. I know the Mk4 means taking off the engine mount (and replacing the bolts as they're stretch bolts.. who the shit uses a stretch bolt for a fucking engine mount anyway?) but surely it's not five and a half fucking hours.

skattrd Posted September 25, 2018 Share Posted September 25, 2018 I've not done one myself, but I've had a couple done at the local garage.Half a day seems about right with various faffing around and scraped knuckles etc. I think we did the last one on a Saturday morning and he shuts at 12, so maybe 3hrs.We definitely didn't use vag.com or anything like that.As for stretch bolts, erm, we might have replaced the original ones. I don't remember anything about those. Link to comment Share on other sites More sharing options...
Asimo Posted September 25, 2018 Share Posted September 25, 2018 Don't bother. Run it until it breaks and then shred the sodding thing. (Dissapointed and bitter one-time Golf 4 owner) AMC Rebel 1 Link to comment Share on other sites More sharing options...
twosmoke300 Posted September 25, 2018 Share Posted September 25, 2018 Not too bad apart from getting the engine mount off on a car with ac Link to comment Share on other sites More sharing options...
willswitchengage Posted September 25, 2018 Share Posted September 25, 2018 What engine would it have if not the 1.9 SDI / TDI? I thought it was only Mk5s got the fancy new common rail 2.0 and 1.6... Link to comment Share on other sites More sharing options...

dieselassist Posted September 25, 2018 Share Posted September 25, 2018 the pre PD Tdi belts are simple enough to do; most of the 5 hours is taking down bits to get to the actual belt; eg on a mk4 golf or skoda Octavia the r/h engine mount has to come off as does intercooler pipes etc etc. I used to sell the odd one or two mk4s n Skoda Octy Tdi's back when they were actually worth a few quid, n a after a spruce up, Id wang on a new fibre belt 'at minimum' -whatever was tippex'd round the engine; as they first thing a caller would ask was 'WHEN WAZ LAST TIMING BELT DONE???" - if it wasn't done they'd want to chip you 500+ off... I used to lock pullys with large welding clamps, drill bits n an M shaped bit of 6mm steel plate ('fashioned' the tongues with a grinder), I made up to lock the 'gearbox end' of the cam... Audi A4 n TAP@ASS are even simpler/quicker to do as its north south facing engine, n the timing belt is facing you at the front of the car; you unbolt 'the front clip' - rad/bumper/latch carrier etc etc to gain acess... I might have a link to an OVERCOMPLICATED yankee how to page, stored on a favourites (possibly)... never needed VAGCOM or VCDS to do a belt/adjust afterwards... Theres a spendy T/B kit you used to buy but I just used to do the fibre belt, n maybe a tensioner if it failed the 'limp wrist' test!! Link to comment Share on other sites More sharing options...
dieselassist Posted September 25, 2018 Share Posted September 25, 2018 heres the link; https://www.myturbodiesel.com/wiki/alh-engine-timing-belt-replacement-vw-jetta-tdi-golf-beetle-1998-2003-part-1/ I seem to remember they want you to 'join the forum' to get p2 n p3, but this will get you started... I never replaced 'engine mount stretch bolts' but did have one snap on me during 'reassembly' when I was a bit casual with the jack up n down approach of the engine (on the sump - bit of wood off cut to protect that) to 'aid acess' to the belt end...

I don't remember anything about those. Someone else did that with this one. If you don't replace the engine mount bolts they snap, and they take a tab off the cast iron engine where it mounts, which causes all manner of issues. Luckily, there's now a handy repair plate to resolve this, but previously, people would scrap the engines for this, as having it removed and the cast iron repaired and re-engineered is a massive expense. Don't bother. Run it until it breaks and then shred the sodding thing. (Dissapointed and bitter one-time Golf 4 owner) It's already broken, and I'm saving it from being shredded. I've got a petrol Mk4 2.0 and a new beetle, so I'm more than aware of what they're like, and actually quite like the damn things. Sorry. What engine would it have if not the 1.9 SDI / TDI? I thought it was only Mk5s got the fancy new common rail 2.0 and 1.6... It's the 1.9 TDI, VE pump with electric timing or some other such nonsense. They also fitted the PD engines to the Mk4. It would be the pre-pd 1.9 tdi VE engine, the veg friendly one. Yep, apparently so. I have a genuine belt kit and Graf pump if you want it for some petrol tokens.. ?? How much would you like? I've got one on order but it might be of dubious quality as it was veh veh cheap. Asimo 1 Link to comment Share on other sites More sharing options...
skattrd Posted September 26, 2018 Share Posted September 26, 2018 Despite not replacing the engine mount bolts I did another 80k or so in my boring and another belt change, using the same bolts. Next time they might get replaced twosmoke300 1 Link to comment Share on other sites More sharing options...

Next time they might get replaced It's a bit luck of the draw. Thing is if they do let go, they drop the engine, cambelt side, against the mount and strut tower and can damage the block mounting points irreparably.Which is why using one time use bolts here is a bloody stupid thing to do. It's bloody stupid, and it frustrates me as Volkswagen used to be far more clever with their cars. Link to comment Share on other sites More sharing options...
twosmoke300 Posted September 26, 2018 Share Posted September 26, 2018 Prob done 10+ plus belts on these and never changed the bolts . Just dont go gorilla on them .Im guessing the people that have done this are the same heavy handed fucks that cant tell 45 degrees from 90 on the 2.0 PD and pull the tensioner stud out of the head Link to comment Share on other sites More sharing options...

Once they've been torqued to yield, they can't be torqued to yield again as they've stretched. Apparently the reason they're TTY bolts is because the used alloy for the mounts and cast iron to mount it too, so as a result the alloy expands and if you've not got TTY stuff in there, it'll rattle loose due to different metal expansion. Which leads me to question exactly why they chose to mount the engine in that manner, requiring the use of TTY bolts in the first place. As I said, the car I'm doing the job on, has already had these bolts fail, where they were re-used after a timing belt change was done. It's damaged the block, meaning I need to fit a repair plate, and it's damaged the cam belt where the mount also scuffed into the covers causing pre-mature wear and damage. Doing some reading, and not only is this very common, it's spawned a product to repair the damaged blocks as a result. The Robert Bentley manual also states that they should be replaced.

shedenvy Posted September 26, 2018 Share Posted September 26, 2018 Can't comment on Non-PD timing belt but my 115PD was about a 6hr job. i had to replace as the water pump bearing nearly shat itself. I re-used my stretch bolts. Yeah they snapped a year later. Renew if the car is precious to you! Link to comment Share on other sites More sharing options...

I'm still not sure what I'll do with it once it's done. I'll probably give the big green dogging machine (petrol 2.0 320k miles Mk4 estate) to Papa Dorson so he can take his Jag off the road for a bit and get the gearbox oil done, and use it for tip runs and trailer tent duties, as I think the 307 is a little better on the old Dino juice, and it's more comfortable. But.. well, I dunno. Link to comment Share on other sites More sharing options...
shedenvy Posted September 26, 2018 Share Posted September 26, 2018 At the risk of making myself unpopular, Mk4s are a useful tool. I've owned 2 115PDs and got them to 313K and 220K miles. They had several issues but only what other makes & models of the same era had. They're not dynamic but will blast along motorways at 85 and return 45mpg. I hated how wallowy mine was so lowered on coilovers - hence the sump /road come-together that may* have caused the shear bolts to snap.So there, wouldn't have another, but if i had one i'd run it till it grenades.
