What happens when car temperature goes down?
If the temps are going down when travelling at speed, this means the thermostat is allowing too much coolant from the radiator into the engine and allowing the temps to decrease, which is actually not a good thing.
What would cause the temperature gauge to go cold to hot?
What would cause the temperature gauge to go cold to hot When driving the car the temperature gage goes to normal temp then to cold then back to normal or hot an this continues happens when you are driving it My car has 1300000 miles. My car has an automatic transmission.
Why does my car have a low coolant temperature?
Consistently low coolant temperatures could only mean one thing; fortunately, the required parts are fairly cheap and easy to install. An engine’s cooling system starts in its water jacket, which consists of a system of empty chambers placed around the cylinders and in the cylinder heads.
What should I do if my car thermostat goes down?
The thermostat valve should be shut; if it’s open even a little, then chuck the thermostat and buy a new one. Replacement thermostats come in varying temperature ranges, and you can typically go up or down 10 degrees to fine-tune engine temperature for the application.
Why is the temperature gauge on my car not working?
Check a wiring diagram of your car to measure the wiring correctly. The next problem is a faulty temperature gauge. However, most temperature gauges are integrated with the instrument cluster on modern cars. In some cases, you can replace the temperature gauge or repair any bad solderings if you find any.
What to do when temperature gauge goes to high?
Q: Temperature gauge goes to high when car is stopped. This can be checked by warming the vehicle up until the thermostat is open, driving the vehicle for a few blocks to get some air flowing through it, stop, turn the motor off and feel the radiator with your hand. Be careful the cooling fan doesn’t turn on.
What does intermittent mean on car temperature gauge?
The code indicates that a wire from the engine coolant temperature sensor, is shorting to ground, or open, somewhere. Of course, “intermittent” means: sometimes. The engine computer, in response, turns on the engine cooling fans, to lower the reported hot engine coolant temperature.
Is it good to check your car temp while driving?
Whether the temperature gauge is telling you the coolant is cool, normal, or hot, it’s always a good idea to keep your eye on it while driving. Any number of things can change the temperature of your vehicle almost instantly.
