Where is the thermostat on the engine?
Locating the thermostat In most cars the thermostat is placed under a housing near the water pump on the cylinder head ; the housing is connected directly to the top radiator hose . In a few cars the thermostat is housed near the bottom hose. Test the thermostat quickly by starting the engine from cold.
Where is the thermostat located on my car?
Typically, where this hose meets the engine is going to be the point where the thermostat is located on your vehicle. Most of the time you can just eyeball the engine and clearly see this hose. It can get a little bit harrier on front wheel drive vehicles where there is no room to see.
What happens when the thermostat on a car is closed?
The thermostat in your car is responsible for controlling the amount of coolant released into your engine. When your car first starts up, the thermostat is closed and does not allow coolant into the engine until it is warmed up.
How can you tell if your car thermostat is stuck?
To quickly tell if your thermostat is stuck, watch the flow of coolant through your radiator. For a more accurate test, measure the temperatures of the engine and the hose leading to the radiators to see if they’re similar.
How can I tell if my thermostat is open or closed?
Take the thermostat out of the pot to see if it’s opened. Pull the thermostat out of the water with your tongs and set it on paper towels to dry it off. As the thermostat heats up, the spring should compress and the center ring will separate from the outer ring to make a gap in the middle.
Where is the thermostat located on a car?
Locating the thermostat on a car isn’t difficult. Find the upper hose on your radiator and follow it to the engine. The end of the hose will be attached to the thermostat housing – the housing really sticks out and is quite obvious once you’ve seen it on a few different engines.
How does the thermostat control the temperature of the engine?
An engine’s thermostat regulates the temperature of the engine by controlling coolant flow. The coolant does exactly what you imagine—it cools the engine down. The engine thermostat can open and close. When it’s open, the coolant flows through, lowering the temperature of the 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.
How to determine if a car’s engine thermostat is stuck?
Remove the thermostat housing. Remove the thermostat. Locate and write down the temperature stamped on the lip of the thermostat. Fill a pot with cold water and a thermometer and place on a stove burner. Place the thermostat into the cold water. Turn the burner on. Watch the thermometer.
