Well My car I changed the head, and the head gasket. The gauge says the engine is overheating, but it is not true, the coolant is perfectly normal and no hose is inflating or whatsoever but the fan is always running.. You can blow your head or head gasket because the sensor is faulty ???!!!! Please I need an answer because I'm using my car for a couple of days even if it says its overheating ( It is not really overheating there probably is a faulty sensor.. ) but i'll stop using it if you can blow you head gasket because of a faulty sensor... !!!

Yes this has happened to me. The coolant temperature sensor tells the radiator fan when to turn on to cool the radiator. When this sensor is faulty your vehicle is overheating and it can cause a blown head gasket if not replaced. I hope this was helpful.

I have an 1998 Subaru Forester - it has overheated three times in five days. The coolant is full and new, the thermostat was replaced today. The old thermostat spring was fully extended, after replacing...


Subarus can be challenging to "burp" Sometimes it takes several attempts to get the air out of the system. The procedure is simple. Top off the radiator, squeeze the hose a few times to help get the air out, replace the cap and start the car. let it idle or drive slowly near home with the heat on high. once the temp gauge begins to rise, if there is no heat get the car back to the driveway before the temp gauge gets half way. Shut the engine off wait for it to cool, at least 10 minutes. Then check the radiator again. If there is still air top off again and repeat. After 3 or 4 attempts if there is still air and or the coolant reservoir seems to be filling, try replacing the radiator cap. If this doesn't solve the problem, It may be a head gasket.

Temp gauge goes up and down


first i would purchase a new radiator cap 15 lbs 16 lb capacity cost about $7..then you must let car cool completely...now check radiator coolant level.. top off if it needs it. Now install new cap..let car warm up normally and after it get to normal temp range or higher put hand on upper radiator hose..it should feel hot and when you squeeze it you should feel a slight back pressure..this will mean that the thermostat and water pump are working correctly. if not either the thermostat you purchased is defective or your pump may not be working properly.
when you use just water in an engine the boiling point becomes 212 when you add the correct amount of antifreeze, depending on where you live, the boiling point will go up to 240 degrees. Make sure you put in the correct amount of mix.50/50 will usually work well. sometimes when a gauge does max out like that it could just be trapped air. if after you checked all this out and no air is trapped in the system, i would think that you may have a bad temp sensor. let me know if this helped thanks.

1995 Mitsubishi Diamante is overheating. Oil pressure light came on - oil was low 2 quarts. Added oil, drove down the street, temp gauge went to Hot. Let car cool down. Drove home, check engine light came...


something is strange here thats for sure ,firstly take thermostat out and put it in a saucepan of water and boil it to see if opens .,check the oil light switch and pull the rubber boot cover back to see if any oil is behind it ??.-You are buying trouble with a car with such a high mileage on it ,never buy anything with more than 50,000 miles or you are just buying someones rubbish

1999 Volvo S70 Stalls at stop signs and traffic lights


These models had a problem with the electronic control modules, and this is what controls the idle speed. Sometimes they just need to be cleaned, but sometimes they are defective. Volvo has extended the warranty on some of them to 10 years or 200,000 miles if it is found to be defective.
