Where is the thermostat located on a 2001 Pontiac Grand Prix?
Follow the upper radiator hose from where it leaves the radiator to where it enters the engine block on top of the engine. This is where the thermostat will be located.
Where is thermostat gasket?
Pointy side up. You have a groove in your intake and that is for the thermostat to rest in and then the tope of your thermostat flange should be just about flush with the intake top. That’s there the gasket or o-ring rests.
Can you put a thermostat in wrong?
Potential consequences of improper installation could include: Electric shock. Blowing a circuit breaker. Damaging the thermostat unit, the electrical system or even the AC/furnace unit itself.
What happens if you put your thermostat in backwards?
Generally when the thermostat is installed backwards, the temperature sensitive spring mechanism is not in direct contact with the coolant until it opens.
What happens if you put a thermostat in upside down?
So if you put it in backwards, the water pump flow will push open the thermostat and cause it to take MUCH longer to heat up. When a thermostat is in correct orientation, there needs to be coolant flow, else the stat will be in dead zone and take longer to heat up.
Do you have to drain the radiator to change a thermostat?
With a normal top-mounted thermostat you need drain only part of the cooling system . Do not drain it while the engine is hot — you may be scalded. Drain the coolant from the radiator tap, or from the bottom hose, until it is below the level of the thermostat housing.
Can I replace thermostat without draining coolant?
You don’t need to drain all of the coolant, no. Just replace what falls out when you pull the hose off to do the thermostat. Air will get into the system when doing the thermostat, there’s really no way around it. You will need to bleed the cooling system when finished.
How do you change a thermostat without draining the system?
Actually, you can change the thermostat in some trucks without draining the radiator. Start with a cold engine. Release the radiator cap to bleed any residual pressure out the system. When you disconnect the hose from the thermostat, a little fluid will leak out, but not much.
How do you fill coolant after changing thermostat?
After replacing the thermostat, refill antifreeze. Leave the radiator cap off, and start the vehicle. Wait five minutes to allow all of the antifreeze to circulate throughout the engine. Turn off the engine, and allow the engine to cool.
Why is my truck temperature low?
Reasons the Temperature Gauge Reads Cold On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.
