I need to do the timing belt on my 99 GS300 and I can't figure out what parts I need. First of all, I have already used the search function on this forum and spent quite a bit of time on google too. There are several kits out there but they don't include the same things. Some come with a hydraulic tensioner and nothing else, some come with a tensioner pulley but no hydraulic tensioner. Then I've also seen a "tensioner adjuster" and idler pulley. After looking at pictures of these parts on rockauto, I think some of them are going by more than one name. Could someone please explain to me specifically what parts I need to do a complete timing belt change?

I am also planning on getting the 2 cam seals, 1 crank seal, and replacing the waterpump at the same time.

Here's a timing belt diagram from this forum:


From what I can tell, the part in the diagram labeled labeled as "Idler pulley," looks like what I've seen called the hydraulic tensioner or tensioner pulley. And the part in the diagram labeled "timing belt tensioner," I've seen called the hydraulic tensioner or the tensioner adjuster. And I don't see anything else that looks like it needs to be changed: all that's left are the gears on the crank and both cams.

those are the same thing people call it differently. i ordered my timing belt kit from a company called am-autoparts my kit came with timing belt, water pump, gasket, studs and bolts for water pump, tensioner, and idler pulley. thats practically all you need to service the timing belt setup anyways.

Thanks for the help. I guess I just need a t-belt, a pulley, a tensioner, a waterpump w/ gasket, 2 cam seals, and a crank seal.
