1997 Mazda Millenia Q&A
1997 Mazda Millenia Question: where is the thermostat located
car over heats and the hoses have been replaced. I let the car set for two days and I took the radiator cap off and a tremendous amount of pressure was released. could it be the thermostat and if it is where is it located? - Visitor
If the car had sat for two days and the system still has pressure check the radiator cap, it has two valves, one releases pressure at about 15 psi the other is a recovery valve allows coolant t be drawn back into the cooling system from the expansion tank. The second possibility is a blown head gasket. The most accurate way to test for a blown head gasket on a gasoline engine is to test for the presence of carbon monoxide in the cooling system. Snap-On, Matco (part # CO 2000), and Napa sell a tool to check to carry out this test. Another link to a supplier of this tool is http://www.etoolcart.com/combustion-leak-detector-lis75500.aspx. Carbon Monoxide is only present if there is a blown head gasket or cracked cylinder head. http://www.arrowheadradiator.com/head_gasket_or_combustion_leak_test.htm I think the napa part number 700-1006. http://www.blockchek.com/instructions.htm . Signs of a blown head gasket are coolant loss (frequently have to top up the coolant level of the engine without seeing an obvious leak), experiencing over heating or rough engine running or the presence of white sweet smelling steam from the exhaust. A badly blown head gasket may allow engine coolant and oil to mix.A friend of mine has had two of these cars both were well maintained but blew head gaskets. - patrick mannion
