- Open your car hood after your car has had some time to cool off.
- Find the thermostat.
- Remove the radiator cap.
- Have someone else start the car for you.
What will occur if the thermostat fails to open?
If the thermostat becomes stuck in the open position, there is continuous flow of coolant into the radiator causing the engine to run cold. Overcooled engines run inefficiently, which leads to increased fuel consumption and higher emission levels and engine parts enduring more wear.
How do I know if my thermostat is stuck closed?
If it is not flowing, wait until your engine warms up. The coolant should warm to the right temperature and begin to flow after 10 to 20 minutes. If it does not start to flow, but the temperature gauge on your dashboard rises, your thermostat is stuck closed.
Do thermostats fail open or closed?
All thermostats will fail in either a closed or open position; there is no such thing as a thermostat that will fail in a “safe” position. Although some brands may claim a thermostat fails in a safe position, it simply locks itself open while it is in a full stroke open position.
Is it OK to drive with a thermostat stuck open?
A vehicle can run just fine if the thermostat doesn’t open. It will run on the warm side, not past halfway, and heat the interior just fine. But, when the weather gets warmer outside that thermostat stuck closed will not be able to allow the reservoir water flow and the vehicle will begin to have overheating issues.
Will heater work if thermostat stuck closed?
If a thermostat was stuck open, the lower radiator hose would start warming up as soon as the engine is started. If a thermostat was stuck closed, there would be no flow even after the engine reached the operating temperature, and the lower radiator hose would remain cool.
When should a thermostat start to open?
approximately 200 degrees Fahrenheit
When the engine is cold, the coolant will not flow through the engine. As the temperature rises, however, the thermostat slowly begins to open. By the time the engine reaches approximately 200 degrees Fahrenheit, the thermostat will be open entirely.
What to do if thermostat is not working?
Why is my thermostat’s display blank?
- Replace the batteries (see the next question if this does not work)
- Flip the AC/Furnace switch on your circuit breaker to OFF then back ON.
- Reset the thermostat – this can be done by flipping the switch from OFF and Heat continuously.
Where is the radiator hose on an Acura Integra?
Follow the upper radiator hose from the radiator to the engine block if your Acura Integra was produced between 1986 and 1994. For models built between 1994 and 2001, follow the lower radiator hose. Locate the thermostat housing at the point where the radiator hose meets the engine block.
How do you change the thermostat on an Acura Integra?
In an Acura Integra, it may be necessary to remove the top of the intake manifold to better access these bolts. Take out the old thermostat. Take note of the position of the thermostat. Seat the new thermostat and gasket in the housing in the exact same position as the old one.
How do you remove an Acura Integra intake manifold?
Remove the clamp from that end of the hose and pull the hose off. Unbolt the two 10mm bolts on either side of the thermostat housing and remove the housing cover. In an Acura Integra, it may be necessary to remove the top of the intake manifold to better access these bolts.
Where to drain coolant from Acura Integra engine block?
Locate a plastic drain plug through that opening. Loosen the plug to drain the coolant from the radiator and hoses into an appropriate container. If the coolant is relatively new and clean, reuse it later. Follow the upper radiator hose from the radiator to the engine block if your Acura Integra was produced between 1986 and 1994.
