Hi,

In your Model :-

The automotive thermostat is a temperature controlled on and off valve.When the temperature rises to a predetermined temperature, thethermostat opens up to allow the engine coolant to flow through thecylinder block and the radiator. This flow is crucial to maintainoptimum operating temperature for fuel efficiency, enhanceddriveability, and engine protection. The coolant flow is reduced whenthe engine is cold, and the flow is increased when the engine is hot.Contrary to popular opinion, operating the vehicle without thethermostat doesn't make the engine run cooler. It will actually runhotter because there isn't a thermostat to slow the coolant flow. Thismeans the coolant doesn't stay in the radiator long enough to dissipateits heat.

TO TEST THERMOSTAT

There are several ways to test the opening temperature of a thermostat.
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.
• Heat the water.
• When the thermostat valve barely begins to open, read thethermometer. This is the opening temperature of this particularthermostat.
• 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 facetoward the radiator. Regardless of the markings, the sensored end mustalways be installed toward the engine.
• When replacing the thermostat, also replace the gasket that sealsthe thermostat in place and is positioned between the water outletcasting and the engine block.

Positioning a thermostat into an engine.

• Generally, these gaskets are made of a composition fiber materialand are die-cut to match the thermostat opening and mounting boltconfiguration of the water outlet.
• Thermostat gaskets generally come with or without an adhesivebacking. The adhesive backing of gaskets holds the thermostat securelycentered in the mounting flange, leaving both hands of the technicianfree to align and bolt the thermostat securely in place.

TO REPLACE THERMOSTAT

CAUTION
If the radiator is filled to thetop with coolant and the engine is run without the radiator cap inplace, the coolant will expand and spill over as the engine warms up.

• 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 thehousing and the mounting surface on the engine. If the gasket remainson either of the surfaces, there will probably bea coolant leak afterreassembly. Some engines use a rubber O-ring to seal a thermostathousing.
• 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. The temperature bulb faces the block.
• When replacing a thermostat, be sure that the thermostat fits intothe groove in the block or outlet housing. If the thermostat isinstalled upside down, the engine will overheat.
• Install the gasket.
• Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
• When the engine has reached operating temperature make sure the thermostat opens.
• You should be able to see coolant circulating within the radiator.
• Another way of checking thermostat operation is to feel the top ofthe radiator hose or use a thermometer or multimeter with a temperatureprobe to confirm that the coolant is warming up.
• If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.

NOTEWhen a paper gasket is used and the recess is inthe thermostat housing, it is a good practice to position thethermostat into the recess and glue the gasket to hold it in place. Ifit falls out of its groove during installation, the outlet housing canbe cracked or a coolant leak will result. Before tightening the wateroutlet housing, try to rock it back and forth to be sure it is flush.Housings are often cracked during this step.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
