Hi,
I, too am interested in this topic. I talked to a local Lexus Dealer and the service manager said that when they change the belt, they also change the rear main seals (according to him, these seals commonly go). Is this true or is this guy trying to make another fast buck?
Also, I've heard that the Toyota Cressida's engine was designed so that if the timing belt breaks, the engine will not have any internal damage. Is this also true for the LS400 (a toyota engine)?
To answer the last question of Vevro, yes, you do need to flush the coolant because of the fact that you've contaminated the existing one when you worked on the water pump.
Any info would be much appreciated!
Thanks!
David
