2002 Toyota 4Runner Question: Timing Belt and Water Pump replacement
Answer #1hemicuda June 16, 2011, 18:14Master
If you have the Timing belt done without changing the pump and the pump goes out 10,000 miles later then you have to pay the same amount of labor to remove the timing belt again and replace the pump and you take a chance of overheating the engine and causing unnecessary damage to your engine. I would change the pump.
