    Q:
    How to replace a Thermostat in a cooling system on 2002 through 2006 Toyota Avalon? Posted by Construcciones T.
    A:
    First of all, a detailed thermostat test can be done when removed. If it stays open at room temperature, it's faulty. To test, suspend it in cold water and heat it, noting the temperatures at which it opens and closes. If it doesn't function as specified, replace it. To replace, disconnect the battery's negative cable, drain the radiator coolant, and disconnect the radiator hose from the thermostat housing. Replace the thermostat and gasket, and reinstall everything. Refill the cooling system, bleed air from V6 models, and check for leaks and proper operation.
