So Fix it

How Replace the Thermostat in a 2001 F150

The thermostat in the Ford F150 uses a mechanical spring to close the gap between the water inlet and the intake manifold. This restricts the flow of coolant to help bring the engine temperature to suitable levels. When the temperature reaches 180 degrees, the thermostat opens up and allows more coolant through the engine. When the thermostat stops working, it will fail to regulate engine temperatures. This could cause serious damage to your engine block and engine heads.

Instructions

1

Follow the top radiator hose from the F105s radiator to where the hose connects to the thermostat housing on the engine. Remove the hose from the housing by loosening the radiator hose clamp with a pair of pliers and pulling the hose off the housing.

2

Remove the two bolts that secure the housing to the Fords engine. Lift up on the housing.

3

Pull the thermostat out of the intake manifold. Place a rag in the hole to prevent debris from getting into the hole while you clean the surface.

4

Scrape the old gasket material off the intake manifold and off the bottom of the thermostat housing with a metal scraper or wire brush.

5

Pull the rag out of the hole and replace it with the new thermostat. The end with the spring goes into the intake manifold.

6

Place a bead of RTV gasket sealer around the mating surface of the thermostat housing.

7

Place the housing on the intake manifold and bolt it into place.

8

Slide the radiator hose onto the thermostat housing and secure it with the hose clamp.
