Timing belt replacement

How big of a job is this on our cars, time and cost wise?
Do it yourself or shell out the coin?

Make sure you check the cam and crank shaft seals to see if they need to be replaced while you're in there by them. Also examine your water pump for leakage or damage because its super easy to swap out while you're doing the belt.

T- belt

The replacement of the timing belt on the first gen "6"s is relatively simple, being a SOHC design. If you have the tools and mechanical aptitude...........Go for it ! A repair manual is always nice to refer to, when working on it. When in there, there's some other things you can check, as previously mentioned.
This is the kind of job that repair shops like to jack the price on. With them doing the labor and replacing all questionable parts, you're looking at about $300.
So save yourself $200 and do it yourself !

The "6"s survival is in your hands !

Take the hit for the water pump and do it as well. Trust me! I replaced my timing belt without doing the water pump and had to repeat the whole procedure over 2 months later when the pump failed and started leaking. If you're new to the car, you'll also have the piece of mind that both are new.

Check your alternator belt too while your at it. If you don't and end up having to replace that later, you'll have to take the timing belt back off. All in all very inexpensive job and not that time consuming.

alternator belt

The two external drive belts are replaceable without taking the t-belt off. But, they both must come off to replace the timing belt. So if it's been awhile, for less than $20, replace these while doing the t-belt.

Very not hard. I would agree with replacing the alternator and compressor belts at the same time. Consider doing the water pump w/ the money you save doing it yourself.

hmm it can actually get pretty costly depending on what is wrong, you should check both the tensioner and idler, just make sure they are not making much noise stuff like that and the bearings seem ok, those can run you about $65 for each water pump is also recommended and that will run you about $60 belt about $40, and i say skip the alternator and serpintine belt since if those break it should be no problem to replace and you will know that they broke by charge light for alternator and loss off power steering and A/C for the other belt.

so in the end your looking at 65 for tensioner, 65 for idler, 40 for belt, 60 for pump, so 230 for the complete job or atleast or the least 40 just for the belt, but i tottaly think you should just go and do the pump at the same time ($100 total). good luck man.

BTW did anyone figure out if our cars are interference engine or non-intereference? I'm considering changing my belt but i don't want to just throw money out if i have a non-interference engine and could just go on and drive till the belt breaks.

I just wanted to add that the above instructions are NOT correct for the 2.2L engine. For the 2.2L engine, you need to align the camshaft sprocket with the "1" mark, not "2" or "3".
