Where is the thermostat located on an IDI?

Once the engine warms up, the gate opens, and the coolant forms a continuous loop through the radiator, keeping the block at a safe running temperature. The t-stat resides in the “Thermostat Housing” (big surprise there), which sits atop the front of the IDI engine. The top of the housing connects to the “upper radiator hose.”

How does the thermostat work in a car?

The thermostat functions as a gatekeeper for the coolant in an engine. It has a mechanical gate that opens when it reaches a specific temperature, ranging from 190 to 195 def F . Once the engine warms up, the gate opens, and the coolant forms a continuous loop through the radiator, keeping the block at a safe running temperature.

Can a faulty thermostat cause an IDI to run erratically?

On these old engines, it’s not uncommon to encounter an erratic temperature gauge. Nine times out of ten, this is the result of a faulty thermostat (t-stat). This is probably one of the simplest repair jobs for the average IDI owner, and all it takes is some basic everyday tools and some cleaners to fix.

Where is the T-stat located on an IDI engine?

The t-stat resides in the “Thermostat Housing” (big surprise there), which sits atop the front of the IDI engine. The top of the housing connects to the “upper radiator hose.” The t-stat is the last stage in a complicated cycle of coolant in the IDI engine.

Where does the thermostat housing meet the radiator?

The thermostat housing is right where the radiator hose meets the engine housing. It looks like half of a metal baseball. When the thermostat becomes stuck, it is reasonable to simply replace it. Also, when the thermostat housing is removed, the housing gasket should be replaced even if you’re just checking it.

What to do when your engine thermostat is stuck?

When an engine is cold, the thermostat should be closed, thus bypassing the radiator. Warm (not hot!) engine test: Open hood and remove radiator cap. Start engine. Observe coolant action. It should be swirling vigorously. When an engine is warm, the thermostat is in the open position.

Why is the engine thermostat in the closed position?

The flow of coolant does not cycle through the radiator unless it is hot and needs to be cooled. When an engine is cold, the radiator fluid is cold, so the thermostat is in the closed position. When the engine starts up, and the coolant warms.
