Your description sounds like the thermostat is faulty. If the thermostat is stuck closed, there will be no heat for the interior. New thermostat's are occasionally bad, it has happened to me. The coolant is leaking from what tube? You can verify the thermostat operation, but unfortunately you must remove it from the engine (but with your symptoms that is the most logical failure). Put it into room temperature water in a pot on the stove. Heat the water and check the temperature at which it opens. This is a near foolproof check, but some thermostats are hard to tell when they open. You might have to pull it out of the water (use care it will be hot) to observe the open condition. In general 180-190 degrees F will be the temperature (water boils at sea level at 212 F) at which the thing is nearly fully open. But that depends on your exact version. The temperature is stamped on some them. For further advice read through the previous posts on overheating or thermostat replacement. Your description sounds like the thermostat is faulty.

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.

your thermostat is closed. needs to be replaced. inexpensive part but can save your engine from overheating.

Waterpump, thermostat, radiator, radiator hoses.

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.

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 is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.

If you have replaced the water pump then flush the radiator with CLR also check to see if the fan is working properly.

I had replaced the water pump and radiator. This had continued to overheat but not as bad. After replacing the head gasket it was finally fixed. I was able to answer my own question only after replacement.

Well ive had the same priblem. We have got new radiator and cap. Then replaced thermostat then water pump. No more problems.

User Avatar

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

User Avatar

After 10 years radiator may be plugged or restricted - try to flush or boil out May need replacement

the thermostat will be under the THERMOSTAT HOUSING, which is where the TOP radiator hose fits on ie(radiator to thermostat housing) this keeps the engine at an OPTIMUM temperature BUT can be A cause of OVERHEATING IF malfunctioning

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.

Check the fan clutch, it may not be working properly.

low radiator fluid or a possible bad thermostat.

A Nissan Frontier may be overheating because the radiator is cracked. A thermostat failure can also cause it to overheat.

Cooling fan not working? Thermostat not opening? Plugged radiator? Water pump not working? Defective radiator cap? you have to bleed the thermostat

User Avatar

clogged radiator, advanced timing, worn water pump, dragging brakes, etc. Usually, the thermostat isn't the real cause of overheating.
