Thermostat possibly installed upside down. Also a possible clogged radiator. we have had the same problems. replaced water pump thermo 3 times flushed sys twice repaired radiator,replaced hoses even left thermo out and still overheating help me too PLEASE!!!!! If you replaced the head gasket, it may not be installed in properly. I.E. coolant passages blocked by gasket. Could be air locked. I had this problem with a 1995 Grand Am. Get yourself a repair manual and follow the entire procedure to bleed all air in the cooling system. Some vehicles have a bleeder valve between the water pump and thermostat housing.
Was the gasket replaced? Have you checked the hose and the heater core. Is everything tightened down?
Replace the coolant, thermostat, turn off the A/c, in emergencies drive with the heater on, increase the air flow through the radiator, have your radiator checked for blockage.
This question is not complete. . Need to know if you've replaced radiator, thermostat, hoses etc. Are you asking this question *after* yo checked the thermostat, changed, added or drained the system?
have the water pump checked
thermostat probably stuck open needs to be checked or replaced
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.
is it just residue from where the gasket is gone?, if not there is a possibility that the head is cracked, was the head checked to make sure it was not warped? and pressure tested?, also you might have an additional problem, radiator blockage,thermostat stuck or if its the k series the dreaded ballbearing problem, each of these could cause the gasket to go again
Have you checked for leaks? also the cooling fan may not be working.
you need to remove the fan the thermostat and the thermostat housing, and the water pump pully and belt. Also you will need to remove the radiator hoses, these should be checked for any holes and replaced if needed.
If you have an old ISUZU Trooper, the radiator thermostat may be not working. Therefore, it will not let cool water from the radiator into the hot engine, even if the radiator is full. Have the thermostat checked and replaced, if necessary. Good Luck
We don't know what relay you are referring to. Check your thermostat and radiator fan. Fluch out your cooling system.
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
