2001 Lexus RX300 Question: Replace timing belt
The water pump does not "have to be replaced" but replacing the timing belt is a relatively big job. If the timing belt only took an hour to replace it would be no big deal to ignore replacing the water pump, but seeing as it is a labor intensive job and the timing belt drives the water pump, once the timing belt is removed the water pump is exposed and easy to replace. The timing belt and water pump have lasted say 90,000 miles and the timing belt after replacement should not be due until 180,000 miles. If you don't replace the water pump now you are relying on the water pump lasting until 180,000 miles. If it fails before this time you are duplicating labor to go back in and replace the water pump. It depends if you plan on keeping your Lexus long term (and can financially in these times afford these repairs). Other items to consider replacing are the timing belt idler, timing belt tensioner, camshaft seals and crankshaft seals. If not replacing them have them carefully inspected. - patrick mannion
My car has 204K plus miles. I changed timing belt around 103K. Miles on car primarily highway. Do I need to change timing belt ONLY or should I buy a timing belt kit (belts, water pump, etc.)? ...
what is the cost of replacing the timing belt
the 2002 lexus rx 300 have a timing belt or timing chain. When should it be replaced?
I have been having my car regularly serviced by a local non-lexus mechanic that I trust. Is it necessary for me to replace the timing belt now (at 95,000 miles) and is it OK for him to do the work...
When I change the timing belt should I also change the waterpump. What would be the cost for both of them.
