You have an overheating problem it's not the radiator or the thermostat?
You say it's not the radiator, but when coolant in radiators is not flushed out at service intervals, corrosion can occur inside the radiator, diminishing coolant flow. This would present as overheating, especially in the summer months. Radiator flush/cleaing services are sold at Jiffy-Lube, etc, but you can get the same chemical packets at Pep Boys, NAPA, etc. Good Luck Also: check to see if you have water coming in your passenger side. Check the floor for wetness, and if it smells like antifreeze. This is your heater core gone bad Defective water pump, fan, fan clutch if equipped, fan thermal relay.
You replaced the thermostat in your 2001 Chevy venture but the van is still overheating the top radiator hose is hard and hot to the touch like the thermostat is not opening up please advise?
How can you tell wheather the radiator or the thermostat is not working because my car has a very serious problem with it overheating?
Why would the radiator fan continue to run after the engine stops after the thermostat was replaced on a 2002 Nissan Altima?
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it…
I'm not a mechanic but, I had to replace my radiator to fix the overheating problem on my 1994. That was the last thing I replaced after replacing the water pump, thermostat, and replaced my fan with a clutch fan. have not had anymore problems with it overheating once the radiator was replaced. Flush the coolant first then replace the radiator. Hope this helps.
If the Toyota Celica VVTI is not blowing hot air through the heater, but the engine is overheating, there could be a problem with the radiator being plugged up. Sediment sometimes builds up in the radiator that can clog thermostats. Another problem might be the thermostat sticking or the water pump is leaking.
1997 sebring convertable that overheats even when the thermostat taken out Need to turn hot air on high to cool it Can anyone please tell you what problem you should be looking for?
The most common cause of overheating is a thermostat stuck in the closed position. However, other causes are: faulty water pump, clogged radiator, clogged hose(s), coolant leak or a broken drive belt. I had a 1987 legend with around 160K that was overheating. Antifreeze would boil out of the overflow. I changed my radiator and it fixed the problem.
