Find out where you're leaking. Anything that causes the coolant to leak out is cause for concern. Fill the radiator. Leave the radiator cap off and start the engine. Watch for bubbles. If there are quite a few bubbles and the coolant wants to blow out even before the engine gets warm, you might have a head gasket problem.
Is your fan coming on?
Inoperative radiator fans, bad water pump, failed headgasket?
It's very possible.
The top radiator hose is above the thermostat. If the top radiator hose is hot, the thermostat is opening. The thermostat is not the problem. Perhaps the radiator is clogged up or the water pump is bad. Look elsewhere.
Have flushed complete cooling system replaced water pump radiator thermostat clutch fan added 2gal straight anti freeze then filled to capacity with water and truck is still over heating. What else could possibly be wrong
If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.
radiator fan, head gasket,
cooling system needs flushed out and a new thermostat installed, also if the radiator is still original it probably needs replaced or rodded out.
Could be a collapsed lower radiator hose, perhaps a bad thermostat.
did you check the radiator or the head gasket?
you must be a wierdo.stupid.
first, make certain the thermostat is not installed backwards, if still hot then remove a radiator hose and see if coolant is discharged with pressure behind it(this checks the water pump); it is also a good idea to flush the cooling system; make sure there is not debris in front of the radiator; beyond all this you may just have to have a professional diagnose it
first of all, do you have the right thermostat? ie: winter, summer. if so i would get the radiator checked, it may be getting pluged.
Coolant at proper level? System air bound and needs to be purged? Water pump not circulating coolant? Defective thermostat? Collapsed radiator hose?
flush the radiator
i would have replaced water pump long before replacing radiator. also check engine oil to see if it has engine coolant mixed in.if it has then the problem is more likely to be a bad head gasket
possiable head gasket
my 1993 Toyota Camry radiator had a hole in it it was overheating. I replaced the radiator. The car is still overheating where is the thermostat located. First, drain your coolant from the radiator. Find your lower radiator hose and follow it to the metal housing. This is the thermostat housing. Remove the 2 nuts with a 10mm wrench. Remove the thermostat and replace with new one and new gasket. Re-install and re-fill your radiator with new coolant. Drive the car with heater running. Allow the engine to cool and top off the radiator. Add coolant to the reservoir to halfway between Full and Low.
It sounds like the thermostat was installed backwards, and is opening/closing based on temperatures from the radiator side and not the engine side.
dose the electric fan run if not check the relay if it runs check the water pump
I would suspect the thermostat is the culprit. Replace the thermostat. definately replace the thermostat, get a new gasket and all. Also, start the car cold and see if the inlet hose to the radiator warms up evenly. if it gets really hot on the engine side of the hose and is still cool by the radiator that means that there is no flow and either the thermo is installed wrong or something is clogged
im having the same problem with my 1994 I've replaced the heater core,thermostat,radiator,i checked the coolant, and it's not over heating or nothing and still no heat lol
Clogged radiator, bad water pump, defective fan or fan thermal relay.
== try changing the thermostat. Make sure system is not air bound Replace radiator cap Make sure hoses are not collapsing under pressure
Check the timing.
