Timing Belt Change

Hi All,
I am planning to change my timing belt when my car hits 60K Miles. I like purchasing from www.ecstuning.com. They have a full kit. The only problems is that their kits are for AEB and ATW engines. My car
has the APU engine. My searches on google show the APU engine showing up on European web sites (UK and Findland). My car is a right hand drive UK spec car sold in the Caribbean.
However the sites that show the APU engines also mention the AEB engine in the same line. Something like this (AEB/ANB/APU/ARK Engines)
My question. Will a timing belt kit for an AEB engine work on an APU engine?
As always - many thanks for your help.

You could try ordering from http://www.eurocarparts.com or http://www.gsfcarparts.com . They're UK parts specialists, so if your car is UK spec they should be able to help.

Hi Chris,
Thanks for the tip. Have those two sites down. They look good but it is so much simpler and cheaper to get parts delivered from the US than from the UK. If push comes to shove I will order from one of the two sites you mentioned.
Can you share any insights on APU, AEB, etc engines. What are the variations on the basic 1.8T engine. There seem to be about 7 or 8 different codes for the A4 1.8T between 1995 and 2001.

The APU engine is listed to be similar (same part numbers) with engines ADR/AEB/APT/ARG/ARK/ANB/AJL. There is however one thing to notice: somewhere between 97-98 the construction has changed so that you might have 152 tooth belt with old tensioner construction or 153 tooth belt with newer (improved). In either cases, get the new 153 tooth version with all the necesary rollers and tensioner (I think the old version is not sold anymore). I had in my 1999 APU the 153 tooth version from the factory.

Hi Petri,
Thanks for the info. My car was manuafactured in September 2000 so I guess it came with the new belt.

So what is the appropriate time to replace the timing belt on a 2000 1.8t quattro?
My manual suggests replacing at 120,000 miles. I'm assuming that this is with the improved tensioner. However, I keep seeing reports of early failure, probably/possibly due to the old tensioner. Unfortunately, no one ever states whether the model had the old tensioner or the new "improved version.

Here in Finland the recommended interval is 90000 km. Quite a cap between these two intervals :-). I replaced mine before 90000 and there was no sign of wear in belt. My speculation is that the tensioner is the most common cause of failure. The recommended interval in Finland might be explained by the strain of winter time.

Hi David, Petri,
Given the damage that can occur spending US $200 to US $400 seems like a small price to pay. I am not an expert but I can see myself changing the belt every at 60,000 miles and then every 40,000 from then on.

I'd love to pay 200 to 400 dollars. However, labor alone is approximately 500 dollars, and to purchase the belt, tensioner, tensioner roller, idler roller, water pump, thermostat, new G12 antifreeze and front camshaft and crankshaft seals is an additional 320 dollars for parts, for a grand total of 820 (plus 7% sales tax).
God knows what I'd have to pay at the stealership>

Hopefully you mean 120.000 _kilometers and not miles!? If you wait with the belt till 120.000 _miles_, then there will most surely be nothing to change ;o(

No, the manual it says 120,000 miles, not kilometers.!!!
I kid you not. My last car, a V6 Toyota Camry (non-interference engine) suggested checking the belt every 60,000 miles. There was no suggested replacement interval.
I replaced the first belt at 120,000 miles, and after driving the car another 200,000 miles the belt is still intact. Of course, I'd never take this kind of chance with an interference engine.

There has to be something wrong here. My (european) manual says 120.000 kms for the t-belt. If they just put "miles" instead of "kms" inthere, when they translated it....then im gonna be ROFLing very soon!
The timing-belt are normally (referring to the manual) changed at 120.000 kms. But we all know (inhere) that this is too high a mileage - so most change it at around 80-90.000 kms. The risk of the belt snapping is simply too high, if you wait the suggested 120.000 kms.

I think you must have misread (or mistyped) this -- that figure would surely be KILOMETERS, not miles.

No, the Audi recommended interval for US 1.8T engines is/was 120k MILES. Really stupid, and lots have broken before then, but thats what they say. I've also heard 90k MILES as an Audi recommended interval, but lots of stories of the breaking around 60-70k. I bought my a4 with 84k miles on it and had all the belts/pullys/tensioners + water pump and t-stat done at 92k.

Thats total rubbish....or should i say hilarious!! Thats (roughly estimated) 160.000 KILOMETERS!!
I would never..ever....EVER, go 160.000 kms between t-belts.

Had mine replaced at 100,000 km and it certainly made a difference to pulley noise. So if you ask me, 100,000 km is the answer.
