I have a 2002 Volkswagen passat with the 1.8t motor with about 120,000 miles. I’ve decided to replace the timing belt for the simple fact that its over the 100,000 mile mark and i don’t see any signs that the belt has been replaced in the past. I’ve been doing a little research and i found out the 1.8t is an interference engine, meaning that the pistons will hit the valves if the timing belt fails, resulting in bending or breaking the valves. So I want to get this done as soon as possible.
So my question is what is a complete list of things i should replace while I’m in there.
also about how long should it take the average back yard mechanic to complete this task with the proper hand tools Ie. no air tools.

I’m not familiar with that engine but I do the belt, tensioner, pulley, water pump if it’s in there, cam oil seals if needed. If you go to rock auto you can usually find kits with all the parts you will need. I just looked there and it looks like the kits come with belt, tensioner, pulley. So water pump must not be in the timing belt? I’m not sure if there are any special tools you need to set the timing on that engine or not.

🙁 what kind of special tools
Also I looked at rockauto as well and I found a kit that does include the water pump. the one I’m thinking i will get is DAYCO Part # WP306K1A
Timing belt replacements are usually pretty straightforward. Sometimes there are special procedures for setting the tension and such. This specific information can be found in the service manual. Having a service manual for your vehicle is a GREAT thing and will pay for itself in a very short time.
VW is very different beast – make sure to look up the car on manual. First of all, many VW do not give you enough room to work on. So you would need to place the car in “Service” position. Takes about 30 minutes to an hour to remove couple of bolts and entire front end disconnects from the frame. If your car requires service position, well only thing I can tell you is it looks really ugly. One time I showed my customer how it looked, he did not want to service the car afterward. Please note that NOT all the cars needs to put into service position for timing belt replacement.
Once you got that out of the way, then next step is aligning of the timing marks, and locking the crank, and cam. Depends on model, all special tools used here. There are no alignment marks on cam/crank pulley for some models. So you have to slide various pin in proper holes to lock the cam and crank in the position BEFORE removing the belt and also check after the belt replacement. The final problem is the timing belt tensioner – which is adjustable. You have to know how to adjust it create proper tension. There are two different tensioners used and both works similar way – turn it clock wise to tension and counter clock wise to loosen – and older model of the tensioner will require a special tool.
With all all the special tools you should be able to do the job in 5 hours.

Now I remember why I don’t like Volkswagons…lol
It really isn’t that bad car to work on. Sure you need to spend some $ to purchase special tools but it is well designed. You have to work on it to appreciate the engineering. No dipstick on Automatic Transmission but the drain bolt has center shaft and is exact length of the transmission fluid level so you cannot over fill it. Unlike BMW ZF you have to heat up the transmission at right temperature and stick your finger into a fill hole to get the level right.
Placing the car in service position is becoming pretty common. You would have to do it for VW, Audi, and Mini cooper. And once the front end detached it would give you plenty of space. The full position require you to discharge the A/C and completely remove the front. But for most jobs you can just let the bumper hang with the A/C line attached.
Thank you everyone for the responses. as an update I have sense discovered that the turbo was leaking oil into the intake side of the turbo, so the turbo was sending oil into the intake of the motor.
As a result I have decided to get out of the car asap, or face the hassle and expense of purchasing a new turbo as well as doing the timing belt and water pump.
As of today I traded in the passat for $3500 at a dealer and purchased a Honda CERTIFIED 2010 Honda Accord.
Again thanks everyone for the awesome responses
