SOURCE: Working on a 2000 Audi A8. Need info on changing

If it's anything like the six cylinder engines from Audi, which I'm very familiar with, and from what I remember of the V8, you have a timing belt that drives the water pump, crank, and exhaust cams, and also includes a tensioner and an idler roller. The timing chains come into play in the cylinder heads. What Audi did was to only drive the exhaust cams off of the crank, using the timing belt, and inside each cylinder head there is a timing chain assembly that is used to drive the intake cams off the exhaust cams. On a periodic service (like the timing service) you only need to do the timing belt. The timing chains are only replaced if the tensioners fail - you'll know this by a diesel-like clatter from the cylinder heads. Failure of the chain drive assemblies is very rare, which is good because they're incredibly expensive (on the V6 engines they're upwards of $700 each). If you're doing this job because it's due based on mileage, don't touch the timing chains in the cylinder heads - only change the timing belt, tensioner roller, relay arm, hydraulic tensioner, idler pulley, water pump, and serpentine belt. You can leave the chains alone.

There are no alignment marks on the camshafts, you must use the camshaft holder tool T40005 in conjunction with the crankshaft holder tool 3242 to properly align the camshaft and crankshaft

CAUTION: Incorrect removal or installation of the timing belt can result in damage to internal engine components.

SOURCE: What are possible causes for

Hi,
For the Audi A8 code P0735 "Gear 5 Ratio incorrect" is a transmission problem and should be taken to a transmission shop that you trust. Have a good day.

Hi have an Audi A3 TDI 2008 the cam / timing belt has broke and I'm looking for timings, can't find any instructions on the internet that look the same, any ideas?


You can purchase manuals for Audi's from Bently Publications. They come on a CD and are loaded onto your PC. However, if the timing belt has broken, there is a good chance that the valves have hit the pistons in one or more cylinders as Audi's have interference engines. This will probably have done serious damage to the engine.

1995 toyota camry If timing belt broke while I was driving what damage was caused?


Whether 4-cyl or V6 there should not have been any, as these are non-interference engines, that is, the pistons do not hit the valves when timing fails. The engine just stops.

Cambelt snapped and I would like to know what damage could have been done


If the motor is an interference motor the valves could have been bent from contact with the pistons after the timing belt broke. If it's not an interference motor then it will be fine once the belt is replaced. What motor does it have?

Timing belt is broken. Interference or non interference motor?


Most Ford vehicles from 1985 and up have enough valve clearence so the valves do not get hit when the timing belt snaps. Since I worked for ford for many years I have only seen one with valve damage and the youg man said he was driving his car really hard at high RPM's. I believe you will be okay on your engine as long as when the belt broke the engine was not at high rpm's. If know one has told you those engine recommend a timing belt replacement every 60k. I hpe this helped and I hope this fixes your problem. Good luck, Roger

Bronken Timing belt. Could this have damaged other things in car


If you 2000 Dodge Stratus is equipped with either the 2.0 Liter (SOHC) 4 cylinder engine or the 2.5 Liter (SOHC) V6 then you have serious engine damage. Both these engines are interference engines. When the belt breaks the pistons will make contact with the valves thus causing damage. The belt on the 4 cylinder should have been replaced at 100,000 miles. The belt on the V6 should have been replaced at 60,00 miles. At 60 mph you for sure are going to have some damage. How much damage, you will know when they open it up.

Broken timing belt. engine turns over and put a wrench on cam shafts and they turn over pretty good


have someone perform a leak down test on each cylinder. This will tell you if you possibly bent a valve on any of the cylinders. If you did you need to remove the cyl. head to have it looked at. If the leak down test is good on all cylinders you should be good with just replacing the timing belt and tensioner. The likely hood that you didn't bend a valve is slim since that motor is an interference motor.

Where is the thermostat on my 2.8 V6 engine 1999?


If it's the same as the 99 2.8 V6 in the A4, it's quite a ways inside the front of the engine. You have to remove a lot of the front of the engine and you'll find it partially hidden behind the timing belt tensioner. Foolish place to put such a part unfortunately, but at least on my A4 that's where it is.
