You need to check your heater core, and blower this are the most probable causes When you flush the coolant on this car, you are supposed to remove the thermostat first-another fine GM concept. IF the there is no volume blowing through the vents, it is a problem with the blower system, not the cooling system. IF it isn't hot but blows okay, it is the cooling system. There is a bleed procedure in this motor as well to remove air pockets. I'd try a t-stat first.
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
hello Can you tell me why the heater on my 2002 toyota yaris isnt working? Ive changed the thermostat,flushed out the radiator and also the heater matrix behind the dashboard is getting red hot as well
Check the fan clutch, it may not be working properly.
Yes your thermostat is working if it is drawing coolant after about ten minutes. It depends on the size of your motor to determine how long it should take to hit the right temp for the thermostat to open up so it can send coolant through the system. If it starts within ten minutes your thermostat is working fine
Lack of coolant, faulty thermostat, radiator fan not working...
Bad thermostat, fans not working or coming on when they are supposed to, bad waterpump, bad radiator or radiator cap.
Plugged radiator, Bad thermostat, water pump not working, radiator hoses collapsing and dont forget no oil
No. What affects engine overheating are: low or dirty coolant; add or flush then use new coolant. Defective engine thermostat; replace it.Plugged, dirty radiator; have it flushed/rodded.Electric cooling fans ( if equipped) not working; repair as needed.
Cooling fan not working? Thermostat not opening? Plugged radiator? Water pump not working? Defective radiator cap? you have to bleed the thermostat
How do you know it is overheating if you have taken the temperature gauge out? Facetiousness aside, it might be worth checking the thermostat switch that stops water circulating to the radiator when the engine is cold.
Bad thermostat? Radiator clogged? System "airbound" water pump not working? Low coolant level? Bad radiator cap?
possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point. possible plugged radiator, sticking thermostat, rad fan not working, temperature sensor not working, low coolant level. that's just a starting point.
