Hello all,

I am the new owner of a 1998 GS300. So far I have done the maintenance on my own such as lower tie rod ends, ball joints, brakes, change tranny fluid. But now I am getting into the timing belt and wont dare do that on my own. My question is where can I purchase a oem timing belt kit? I have searched here and couldnt find anything and when I google it I only get aftermarket kits.


Also, what is all included in the kit and should be changed at 145,000 miles?

Thanks in advance!

 

Anyone..................?

 

theres a ton of stuff the may need to be replaced depending on the shape of the car. As for timing belts kits, Toyota does not make a "kit". You should at least replace the t-belt, drive belt, and waterpump. If the cam seals are leaking and any idler bearings making noise, that would be the time to replace those aswell. Plugs, pcv, air filter, cabin filter, gas cap gasket, tranny fluid, and rear diff. fluid should be changed also if it hasnt been done recently

 

Does anyone know what the replacement mileage would be for my car? I don't have my shop manuals yet and I'm just wondering. So far (5000 mi) just love the car. Thanks for your reply. Handles great in the Central Oregon snow and ice.

 

unless you have some rare 07 16series GS, you're in the wrong section.

as for replacement kits, can't you just goto the dealership and ask? or did you check out our sponsor's sites???

 

It's really not that hard to replace the timing belt, especially that you engine is non-interference, AFAIK. I just did it on my LS400, and honestly the hardest part was getting the high temp sealant from the engine block that was left from the old water pump.

What you will need to do the job:
Timing belt - obviously.
New crank seal - recommended.
New cam seals - not really necessary, it adds much more work to change them, and unless they are leaking I wouldn't bother.
New idler pulleys - much recommended, with 150K your original pulleys are probably worn.
New water pump - even more important then the timing belt. If the old pump starts leaking, you will have to remove everything again, and chances are you will need new belt and and pulleys, because the leaking antifreeze will damage them.
You might also need some O-rings/gaskets (thermostat, water inlet housing, water by-pass pipe). I dont know which ones the 3.0 engine needs, but you should replace all of them. You will know once you take everything apart.
Also you might want to consider replacing the timing belt tensioner. Its usually quite expensive - roughly $100, and I would test the original one, and if it's good and not damaged by leaking antifreeze, I would leave it alone. It's a very simple part that doesn't really go bad. Also you dont have to remove all that much to replace it in case it ever goes bad.

As far as the tools, you need your basic (metric) tools, plus:
1/2" Breaker bar + three or four foot steel pipe, for extension (will come handy when remove crank pulley bolt).
Set of allen sockets to remove idler pulley.
Threadlocker or locktite.
High temp sealant for your water pump, unless it comes with a gasket.
Scotch brite and razors to remove old sealant from the engine block.

Thats pretty much it. I struggled a lot with my LS timing belt, but it was only because I've never done it before, and didnt have the right tools right away. The first time around I put the belt on wrong, and the car wouldnt start, so I had to take everything back apart and put it back together - and it only took me 3 hours to do it all the second time around, because by then I already knew exactly what goes where.
