It could be that the thermostat in the top of the radiator is jammed shut.

The thermostat prevents water circulation while the engine is cold and opens when the engine reaches its working temperature. If the thermostat fails, the the radiator cannot cool the engine.

Try replacing the thermostat, it shouldn't be very expensive.

1994 vw golf 1.9 overheating


First question is what constitutes "overheating".
Since the car has been parked for years, the thermostat could be sticking closed.
The cooling system could have air pockets and need to be bled.
The water pump may be corroded inside and not pumping enough volume.
If the gauge goes above half way, the fans should start up. But half way should be more or less normal, not hot yet.
I would look at flow problems first, beginning with removing the thermostat and driving it without one for a few days. Also check and see if there is a process to bleed the cooling system of air.

I have no heat in my 2002 Tahoe. Could it be the Thermostat or the Heater Core? I really can't afford to take it to a dealership or a mechanic right now. Would like to do the work myself


When your driving down the road what does your temp gauge read? If it is in the normal place, about the middle, than the thermostat is working. The next thing to check is the coolant level. Make sure the overflow and the radiator are full. If the radiator gets low enough the first thing to stop working is the heat. If both of those are full than feel the hoses going to the heater core. They should both feel hot with the engine fully warmed up. If one is cold and one is hot than the heater core is plugged. Back flushing the heater may bring it back to life. Check those out first. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

I have a really strange problem with my Nissan 2006 Pathfinder. The heater will not heat up and blow out hot air as long as the vehicle is sitting idling. When I want to defrost the windshield on frosty...


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps y

It sounds normal, but perhaps the radiator is a little small. Make sure the core is clean by blowing it out with compressed air (from the engine side) to clear out bugs and other debris. Make sure the overflow/reserve tank is at the proper level. Check the coolant level in the radiator when engine cold--it should be right at the top of the filler. These are all preventive, not a cure for anything.

1986 Pontiac Trans Am Overheating


Its overheating when you go up long hills because the engine is not getting adaquete air in the system. The radiator is angled to get optimal air a certain way. It may overheat but you shouldn't start seeing smoke.
