Why is new thermostat leaking?
If it is coming from the thermostat location in the housing, it could simply be a thermostat gasket/O-ring leaking. If the leak is coming from any of the hoses, the leaking hose and clamp will need to be replaced. A cooling system pressure test would uncover the leak location.
What happens when your engine thermostat is stuck?
A thermostat that’s stuck open will circulate coolant through the radiator at all times, even during cold starts. As a result, the engine may never reach full normal operating temperature, and the coolant temperature gauge may hover at a point that’s colder than usual.
What happens to coolant when the thermostat is opened?
As the thermostat opens, the flow of coolant is gradually diverted into the radiator instead. Thermostats have a temperature “rating” (such as 180 or 190 degrees Fahrenheit) which is the temperature at which the thermostat begins to open. It will reach the fully open point approximately 15 to 20 degrees higher.
Why is my water pump and thermostat not working?
The radiator, water pump, and thermostat are definite possibilities, but there are a few others that are possible also. A faulty cooling fan is the first thing that comes to mind, but it could also be a head gasket issue, clogged coolant passages inside the engine, or faulty radiator hoses.
How can I get the thermostat out of my car?
The thick black hose runs from the side of your radiator and attaches to the top or side of your engine block with a tube clamp. Use a screwdriver to loosen the nut on the tube clamp and then pull the hose off of the engine. Set the end of the hose aside for now so you can access the thermostat housing on your engine.

What to do when your car thermostat is out?
Reattach the radiator hose and hose clamp. Lower the vehicle and refill the cooling system. Start the engine and monitor the coolant level, being sure to get out any air bubbles. To ensure air is removed from the system, run the engine for about 10 minutes with the heat on.

What to do if coolant comes out of radiator?
You can warm the car up with the hood open and wait to see where coolant comes out. Be careful not to get sprayed with hot coolant though. If your so inclined, you can rent a cooling system pressure tester from your local auto parts store. You connect it to the radiator filler neck and pump pressure into the cooling system.
