Posted on Jan 02, Hi, In your Model: When the temperature rises to a predetermined temperature, the thermostat opens up to allow the engine coolant to flow through the cylinder block and the radiator. This flow is crucial to maintain optimum operating temperature for fuel efficiency, enhanced driveability, and engine protection.

    The coolant flow is reduced when the engine is cold, and the flow is increased when the engine is hot. Contrary to popular opinion, operating the vehicle without the thermostat doesn't make the engine run cooler. It will actually run hotter because there isn't a thermostat to slow the coolant flow. This means the coolant doesn't stay in the radiator long enough to dissipate its heat.

    One method does not require that the thermostat be removed from the engine. Remove the radiator pressure cap from a cool radiator and insert a thermometer into the coolant. Start the engine and let it warm up. Watch the thermometer and the surface of the coolant. When the coolant begins to flow, this indicates the thermostat has started to open. The reading on the thermometer indicates the opening temperature of the thermostat. If the engine is cold and coolant circulates, this indicates the thermostat is stuck open and must be replaced.

    The other way to test a thermostat is to remove it. Suspend the thermostat completely submerged in a small container of water so it does not touch the bottom. Place a thermometer in the water so it does not touch the container and only measures water temperature. When the thermostat valve barely begins to open, read the thermometer. This is the opening temperature of this particular thermostat. If the valve stays open after the thermostat is removed from the water, the thermostat is defective and must be replaced.

    Several types of commercial testers are available. When using such a tester, be sure to follow the manufacturer's instructions. Markings on the thermostat normally indicate which end should face toward the radiator. Regardless of the markings, the sensored end must always be installed toward the engine. When replacing the thermostat, also replace the gasket that seals the thermostat in place and is positioned between the water outlet casting and the engine block.

    Positioning a thermostat into an engine. Generally, these gaskets are made of a composition fiber material and are die-cut to match the thermostat opening and mounting bolt configuration of the water outlet.

    Thermostat gaskets generally come with or without an adhesive backing. The adhesive backing of gaskets holds the thermostat securely centered in the mounting flange, leaving both hands of the technician free to align and bolt the thermostat securely in place. Drain some coolant into a clean container until the coolant level is below the thermostat housing. Remove the upper radiator hose connection from the thermostat housing. Loosen the housing bolts and remove the housing.

    Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing. Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings. The temperature rating is stamped on the sensing bulb on the bottom of the thermostat.
