Engine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.
try a radiator cap......or you have a head gasket leak.
it can..rain has NOTHING to do with your radiator or the thermostat
possible radiator resrtiction

first check to make sure your fan comes on. if it does then there are several things that could be wrong. first do you have enough water/antifreeze in the radiatior. check to make sure you have no leaks. then replace the thermostat located in the top radiator belt housing connected to the motor. if it still overheats try replacing the water pump. if it still overheats after that check your oil to see if theres water in it if there is you blew a head gasket
There is a sensor that shuts your engine down when it overheats you should check your coolant level, check the coolant fan, check your thermostat to see if it is open,check to see if your radiator is plugged or restricted, check radiator cap, check to see if any hoses are collapsed, and check system airbound.
Yes, if the radiator is clogged and the engine overheats. The main cause of head gasket failure is the engine overheating.
Blown head gasket?
it means it is time to get a new one
The cooling system is closed, and unlike NASCAR there is no fail safe way for fluid to escape if it overheats. instead the pressure will force the fluid through the weakest point in the system. Usually where the hoses meet the radiator or the block are where you will first notice the gas escaping
Could be bad fan relay?Could be a plugged or restricted radiatorCould be a bad radiator capCould be a bad thermostat
check the heater core stopped up radiator
clogged radiator or bad water pump
put a new one in
I belive it might
your electric radiator fan might not be working,check fan fuses
depending on how much it overheats.... you can blow a head gasket...warp your heads ... crack your radiator..
car overheats and produces steam/smoke. may crack engine block or head.
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
Be care-full my radiator blew up and burnt me. I replaced Radiator, thermostat, and water pump. Timing belt is in the way so I replaced it too. OK Now
Cooling lines from transmission to radiator?
Consider replacing your radiator cap . .
