Thanks for choosing FixYa and welcome to the site. The thermostat is the most common issue with overheating. This is just a recap of other issues that can cause overheating. Be sure to check your coolant level and make sure you are not leaking coolant in the engine compartment. You may need to buy a new coolant cap. Make sure your fans are working properly. If they are not, check the fuse for the fans. Make sure your radiator is not leaking and working properly. Make sure there ae no damaged hoses or missing clamps. If all this checks out, it may be your water pump. If you have any questions, just let me know. Thanks for using FixYa.

As long as there aren't any leaks, I suspect you haven't got cooling system completely full. Air in system will cause it to overheat. Run car up to normal operating temp with radiator cap off and add coolant.

Temp gauge stays cold


If the thermostat is bad (i.e. stuck open at all times), this would allow coolant to circulate in the engine even when it is below the desired operating temperature. This leads to OVERcooling of the engine. You can either replace the thermostat as a first step or remove it and test it -- closed when cold, open when heated above 190-200F.

99 mercury cougar v6 2.5L, temp gauge is reading hot after thermostat change why? is it a air bubble or is it a bad temp. sending unit? any other ideas? please help


May be a defective thermostat or place in the wrong direction. If it's properly installed, might want to check the fan operation which may be producing the overheating.
If fan is good, one way to remove air in the coolant system is to run vehicle while all heaters on. take extra coolant and stop along the way to top off if needed. While driving, keep listening for the fan to begin running when vehicle reaches high temperatures.
If you continue to experience overheating, may want to take to a local known repair shop for further troubleshooting.

I have a 92 accord LX. I have replaced the Radiator and the hoses, thermostat and fan switch. Car is still reading hot in a matter of 5 to 10 mins of running. Fluids are topped off. I am not sure why it is...


If you have no air in the system, cooling fans & water pump are working properly, and you didn't install the thermostat backwards, you could have a head gasket problem. Also, make sure the gauge is reading correctly, and the engine is actually hot & the gauge is not giving you a false reading.
If you installed the thermostat upside down, it will not open to allow coolant to circulate. This 5-10 minute time frame you give points to a water pump or thermostat.
I hope this helps.

My 99 ford f150 pu can sit for 30 to 40 min warming up to operating temp then I leave for work and go aproximatley 15 to 20 miles and loose heater then the engine over heats. After a few min it boils over...


Change the thermostat. The thermostat might be opening too late to circulate. From doing so the coolant is just sitting there getting hotter and hotter which would cause overheating until the stuck thermostat decides to open. I would bring the car to a safe temperature and feel the radiator hoses if one is hot and the other isn't? You have a thermostat problem. Easy fix and cheap. I wouldn't run the vehicle too long until you fix it.

99 Firebird still overheating after repairs and antifreeze


overheating is most likely a bad thermostat, but the coolant loss is a second big concern. Does the exhaust look like steam? You could have a cracked block and the coolant is leaking into the engine. Also check the oil for contamination.
