A defective thermostat can cause the engine to overheat. It can also cause the engine to not reach full operating temperature if the thermostat is stuck open. It is possible this could set the check engine light.
It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.It could cause the check engine light to come on with a code concerning cooling system/thermostat performance.
I would suspect the thermostat is stuck open. Replace the thermostat.
check the water pump
doubt that a t-stat would cause a car to shut down and restart when cold check for an ignition module proublem
The thermostat would be the first thing I would check.
you may have an overcooling problem. check your thermostat and temperature switch. the thermostat regulates fluid in and out of the radiator, and the switch tells the fans to come on to cool the engine.
Check the engine thermostat. Its probably stuck open.
A fuse does not cause the check engine light to come on. Modern cars have a bunch of little sensors. Each one can set off the check engine light. You can hook your car up to a computer and check it out to find out which one it is. You can even hook up a wire and a little bulb and count the number of flashes. You can check it out. The number of flashes can tell you what is wrong. For example, on some chevrolets 015 is a sensor right above the thermostat. If that one goes off, it might be time to change the thermostat.
Yes it can.
Check coolant level Perhaps thermostat is sticking and needs replacement
It is possible. A more likely cause is the gas cap was replaced incorrectly or left off after getting gas
The actual removal of the thermostat will not cause this condition but if you possibly disconnected a vacuum hose white changing the thermostat, WOULD cause that problem. Check all of the vacuum hoses to make sure they are connected and tight.
