Highlander with 75,000 miles. No water pump noises, no visible leaks and no obvious loss of coolant from the reservoir.
Does crust build up at water pump weap hole mean the pump has to be replaced? on 2007 Toyota Highlander Hybrid
IF TIMING BELT HAS NOT BEEN CHANGED THEN IT IS ABOUT TIME FOR IT. MAY WANT TO HAVE WATER PUMP INSTALLED AT THAT TIME.
