this is going to be my first time doing a timing belt and water pump job. i have a 98 gs400 and it has 258k miles. i do have a leak. i have to fill coolant every 4-5 days from low mark to full. i do not know when was the last time this job has been done on this car. let me know if im missing any parts for the job. i will be ordering timing belt, accessory belt, water pump and gasket, crank seal, and timing belt tensioner from rockauto. i know there are diy guides on this but are there any videos? thanks

 

Everyone will tell you that its best to order these timing belt and water pump parts from Toyota and i agree.

You could call sewell Lexus and have them give you a list of the necessary parts needed.

 

And at a discount ^^^

I have installed this kit on GS's, a LS, a 4Runner and a Landcruiser.
No difference from dealer other than price...

 

Just had mine done by Lexus like 150 miles ago, good luck man hope it works out for you...
