Hard water, and calcium can build up insite the hoses and get released in chungs during the flush process. These pieces can get caught in the thermostat and cause it to fail. You can try removing the thermostat or just replace it as it is an in-expensive part. You might consider re-flushing the radiator as more calcium might hit the thermostat after replacing it.
The 1999 Cadillac thermostat can be found on the front of the engine. The thermostat will be inside of the thermostat housing. You can follow the top radiator hose directly to the thermostat housing.
The thermostat on a 2001 Cadillac SLS is located in the radiator. To access it, remove the upper hose assembly after draining the radiator halfway.
By the thermostat
Engine end of the upper radiator hose
Low coolant? Radiator probably needs flushing and/or replacing after 40 years. Bad thermostat? System airbound? Water pump not circulating coolant? Hoses collapsing? Bad radiator cap?
Usually in housing at engine end of top radiator hose
Make sure the radiator is full of water, don't just check the overflow tank, but do make sure the car is cold before removing the radiator cap. Also the thermostat could be frozen closed or you could have a failed water pump. Try replacing the thermostat and flushing the cooling system first. Don't forget to buy a thermostat gasket when purchasing the thermostat.
Drain the radiator. disconnect the top radiator hose from the engine. Remove the water inlet that the hose was hooked to. The thermostat is in the housing. Replace the gasket when replacing the thermostat.
Usually at engine end of upper radiator hose in housing
Probably at the engine end of the upper radiator hose
near the thermostat housing
It's overheating when driven because there is much more heat to dissipate than when it is just idling. Your radiator might need back flushing or your thermostat needs replacing. Change the stat first, then flush the radiator.
located n housing at end of upper radiator hose.
The first step in how one can replace a thermostat in a 2001 Cadillac DeVille is to remove the housing which surrounds the old thermostat. The radiator hose will need to be removed and drained and then the thermostat can be removed. Remove the old thermostat gasket and then insert the new thermostat as well as the new gasket. Attach the radiator hose and place the drained fluid back into the radiator filler cap.
Very possibly. You can check a spark plug and see if they are wet or you can see if there is gasoline in the coolant liquid.
Follow the upper radiator hose from the radiator to the engine and at the engine you will find a housing with the thermostat inside. When replacing it make sure the spring goes toward the engine.
The cost varies widely depending on the make and year of the vehicle.
check your thermostat to see if its opening.
Your radiator cap is made of metal and rubber. The metal and rubber are reacting to the rust in your radiator. Rust and oxidation in your radiator will deteriorate the cap at an accelerated rate. I suggest flushing the cooling system and replacing the coolant and cap. If it persists after that you might have a heat problem that is cooking the rubber right off the radiator cap. If this is the case you should check your thermostat and heating Coil.
Follow the upper radiator hose from the radiator to the engine. Where it meets the engine there is the thermostat in the housing. Make sure you install the spring TOWARD the engine when replacing it. GoodluckJOe
Follow the upper radiator hose from the radiator to the engine and there you will find a housing with the thermsstat inside. When replacing the thermostat make sure the spring goes toward the engine.
Follow the top radiator hose down to the water outlet on the engine. It is in the outlet.
It is located at the engine end of the upper radiator hose. Take the thermostat housing off. When replacing the thermostat make sure the spring goes toward the engine. It is not the upper radiator hose...it is the lower one..
You need to burp the radiator and cooling system.
