How to Remove a Thermostat on a 1990 Lincoln Town Car 302 Engine

A thermostat is a device that regulates the flow of coolant through an engine. It is usually located in the upper radiator hose or in the intake manifold. A faulty thermostat can cause an engine to overheat or run too cold. If you are experiencing problems with your engine, it is important to check the thermostat.

To remove the thermostat on a 1990 Lincoln Town Car 302 engine, you will need the following tools:

• Socket wrench
• 1/2-inch socket
• Pliers
• New thermostat

Once you have gathered your tools, you can follow these steps to remove the thermostat.

Step 1: Disconnect the negative battery terminal

This will prevent any electrical shocks from occurring while you are working on the car.

Step 2: Locate the thermostat

The thermostat is usually located in the upper radiator hose or in the intake manifold. On a 1990 Lincoln Town Car 302 engine, the thermostat is located in the intake manifold.

Step 3: Remove the bolts that hold the thermostat housing in place

There are two bolts that hold the thermostat housing in place. Use a socket wrench and a 1/2-inch socket to remove the bolts.

Step 4: Lift off the thermostat housing

Once the bolts are removed, you can lift off the thermostat housing. Be careful not to spill any coolant.

Step 5: Remove the old thermostat

The old thermostat is held in place by a spring clip. Use a pair of pliers to remove the spring clip. Once the spring clip is removed, you can lift out the old thermostat.

Step 6: Install the new thermostat

Insert the new thermostat into the thermostat housing. Make sure that the thermostat is oriented correctly. The spring clip should be on the top of the thermostat.

Step 7: Replace the thermostat housing

Place the thermostat housing back onto the intake manifold. Make sure that the gasket is in place. Tighten the bolts that hold the thermostat housing in place.

Step 8: Reconnect the negative battery terminal

Once the thermostat is installed, you can reconnect the negative battery terminal.

Step 9: Check for leaks

Start the engine and let it idle for a few minutes. Check for any leaks around the thermostat housing. If you see any leaks, tighten the bolts that hold the thermostat housing in place.
