What type of system do you have? Heat pump? With or without supplemental electric strip heat? Warm air furnace? Need to know in order to help.
To test a home thermostat, you can turn on the heating or cooling system and set the thermostat to the desired temperature. Wait for a few minutes to see if the system turns on and starts heating or cooling the room. You can also use a separate thermometer to check if the temperature matches the setting on the thermostat. If the system does not turn on or the temperature does not match, the thermostat may need to be calibrated or replaced.
ask your service station to do a compression test. I had the same problem and replaced all sensors and thermostat but after the test it was found out that there was a crack in the housing holding the thermostat
To test your thermostat, you can turn on your heating or cooling system and set the temperature to a level that is different from the current room temperature. Then, wait a few minutes to see if the system turns on or off as expected. You can also use a thermometer to check if the temperature matches the setting on the thermostat. If the system does not respond or the temperature does not change, your thermostat may not be functioning properly.
A car running hot after it has been started could be blown head gaskets. The thermostat may also need to be replaced.
To test your thermostat, you can adjust the temperature setting to a level different from the current room temperature. Wait a few minutes to see if the heating or cooling system turns on as expected. You can also use a separate thermometer to compare the room temperature with the thermostat reading. If the system responds correctly and the temperature readings match, your thermostat is likely functioning properly.
Replacing a thermostat on a 1989 Audi 100 should take an estimated 15 minutes. First you will need to disconnect the radiator hose by taking off the two clamps. Then you will remove the two bolts holding the housing in place. After the bolts are removed, the old thermostat can be taken out and replaced with a new one.
Had this happen once. Found out the thermostat was'nt opening. Replaced it and everything worked fine. Watch your heat gauge, if after a few minutes of the engine running and the gauge goes from nothing to hot imediatly instead of gradully, you;ve probably got a bad thermostat.
You may want to consider replacing the thermostat.
Yes your thermostat is working if it is drawing coolant after about ten minutes. It depends on the size of your motor to determine how long it should take to hit the right temp for the thermostat to open up so it can send coolant through the system. If it starts within ten minutes your thermostat is working fine
It would also depend on how cold is cold, 35 degrees F below freezing or 35 degrees F above freezing.
Bad cooling fan or thermal relay. Bad water pump, clogged radiator.
It could be that you are low on coolant, but if that is not the case, your thermostat may be stuck open. After the vehicle has been running for about 15 minutes, put your hand on the top of the radiator. If it is not too hot to touch, your thermostat should probably be replaced.
