Change your thermostat.
You may have the thermostat in backwards. The spring side of the thermostat faces into the engine.
You have not bleed the air out of the system after you installed the t-stat, causing the heater not to work and the engine to overheat. Use a coolant filler that screws into the radiator and get the air out
There are several things that can cause your 1992 Mitsubishi Eclipse to overheat. A malfunctioning water pump or a blown head gasket should be the next things that are checked.
thermostat is more than likely stuck shut from the overheat. Have to be changed.
Sell It!!!!!
check the thermostat housing isn't broken where the thermostat pin pushes on the plastic housing fault with polo's
water pump
If the rad. has never been changed I would look there. Also, not knowing the history, did the car overheat before ? Why did you change the thermostat ? Is it possible that it never overheated before, but since the new thermostat it does now. Then possibly the new thermostat is defective. OR, it did overheat before and someone told you to change the thermostat, and it still overheats ? AT idle ? On the road, city or hi-way ? Again have the rad. checked. Sometimes even if the rad. looks good, it could be the main problem. Also, if it overheats on the hi-way only, it is possible the cooling fins on the rad. tend to bend and close and not let air through. If you give me more info on my Msg. board, we can find the problem. Good luck. Hope this all helps to find the problem. Also, be sure to mix your prestone at least 50/50. Or 60 prestone 40 water. This helps for cooling.
Type your answer here... IF WE CHANGED ONLY COOLING FAN THEN IT WILL BE OVERHEAT BECAUSE WE DON'T CHANGE OR FLUSHING OF RADIATOR. WE CAN REMOVE THERMOSTAT VALVE ALSO MAY BE HOSE PIPE WILL BE BEND
My 2001 Nissan frontier 3.3 v6 engine is overheating. I changed the thermostat but it still overheats.
Change the thermostat. lol. Simple but the water pump wont work if the thermostat is stuck closed. Good luck. Kyle
