I just got off the phone with my local lexus dealer. He quoted me a price of $455.00 to do the belt and a total of $900.00 to do the belt and water pump!! He told me that you only save about $150.00 labor changing the waterpump when having the belt replaced. I called back to make sure that I understood what he said and he replied that $900.00 was the going price.. I called a toyota dealer the price fellto $619.00 then called two different independent shops and the price fell to about $500.00 Everyone that I talked to said it was only about $180 more to do the water pump while doing the belt. The dealer wanted$445 to do the pump. I get so tired of getting the shaft when dealing with a dealer
