Try pumping the brakes 3 or 4 times with the truck running in 'park'.

SOURCE: no heat in 97 mercury villager

your heater core may be getting blocked up, or the thermostat may be stuck open at times. you have a few options here, option 1 and 2 cost about the same, option 1: have the thermostat replaced just so you know its working properly, a 97 will most likely not have a telltale way of knowing if the thermostat is bad or going bad. option 2. have the cooling system flushed at a shop. this will try to clear out and debris in the cooling system that may be blocking passages or the heater core. option 3 is the most expensive. have the heater core replaced, the heater core is what provides heat to the hvac system in the dash. a few other things to check would be vacuum lines/actuator/temperature door on your hvac system.

SOURCE: 2000 chevy silverado normal operating temp 210 ,

With the truck running at operating temperature, squeeze your upper radiator hose. You may have to check it a couple times allowing time for your thermostat to open. Are you able to compress the hose a little when you squeeze it or does it remain stiff/solid? Your thermostat may be stuck open or even stuck closed.

Cheverolet 2500hd truck thermostat stuck closed


I think it's the hot water valve also, at least check it by feeling the hoses that go from the heater to the engine,
If hoses are hot, then its ok. it's a sign that hot water is circulating
and you should go ahead and drain the coolant and see if it's dirty, or has stop leak, and refill the radiator with fresh coolant, be sure to pour in as slow as you can. be patient
now at least you changed your coolant, and no air pockets trapped in the system. go from there. if it's the hot water valve you can look it up on you tube.

My 2008 dodge ram temp gauge goes from normal to high ,check gauge lite comes on in a few minutes temp gauge goes back to normal but heater will only blow cold air I,ll shut heater off wait a few minutes...


Souds like it's way low on coolant. The heater will blow cold air when the cooling system is so low that there is no water (coolant) running through the heater core. Then the thermostat opens, it trys to be normal but the system is low so it gets too hot in just a few minutes. If its that low, there must be a leak somwhere.

The temp gauge on my 2008 ram 1500 jumps from normal temp to hot checked engine the temp is fine my heater them puts out cold air and I have no heat if I shut heater off and wait a few minutes temp gauge...


It probably low on coolant. The heater will blow cold when there is not enough water (coolant) to keep the heater core full. Check the radiator (not the overflow reservoir) when it's cool.

2006 chevy silverado 2500hd truck heats up to operating temp while in parking lot blower works well but truck will not blow any hot air until truck is driving at at least 15 to 20 mph. fuses good think...


If I understand you correctly, your temp gauge shows correct operating temperature, your blower fan blows air that you can feel with your hand from the right floor or dash outlet, but that air doesn't feel warm until you are moving?

If so, several possibilities come to mind. One is that your coolant level is low. Even though your temp gauge reads in the right range, the coolant level could be low enough that it doesn't reach the heater core until there is enough engine RPM to create more pressure from the water pump and force what coolant is there toward the heater core. Another possibility is that your heater controls are not able to do their job. A stuck flapper in the duct or a malfunction with the temperature control system could be causing the problem, and at 15-20 MPH there is enough air coming through the outside air vents to provide some heat.

I'd check the coolant level first, though. The other possibilities are more far-fetched.

05 Silverado, overheats when in 4-wheel drive under strain. Fixed once(so I thought) by replacing the water pump and thermostat. Happened a few months later. Again, 4-wheel, under strain. Wound up...


Instrument cluster - GM had problems with a part inside the cluster , Stepper motor , These faulty step motors caused the gauges to act erratically . 2003 to 2006 ! ALL GM vehicles . Just replaced a cavalier instrument cluster for what customer thought was a over heating problem .The fans come on low speed when engine temp. reaches 220 degress
The PCM commands the low speed cooling fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 104.25°C (220°F).
• A/C refrigerant pressure exceeds 1447 kPa (210 psi).
• After the vehicle is shut OFF if the engine coolant temperature at key-off is greater than 101°C (214°F) the low speed fans will run for a minimum of 60 seconds After 60 seconds, if the coolant temperature drops below 101°C (214°F) the fans will shut OFF. The fans will automatically shut OFF after 3 min. regardless of coolant temperature.
The PCM commands the high speed fans ON under the following conditions:
• Engine coolant temperature exceeds approximately 107.2°C (225°F).
• A/C refrigerant pressure exceeds approximately 1824 kPa (265 psi).
• When certain DTCs set.
At idle and very low vehicle speeds the cooling fans are only allowed to increase in speed if required. This insures idle stability by preventing the fans from cycling between high and low speed.

Engine Coolant Hot Message Noticed AC was blowing hot and looked at instrument panel and saw message above. Drove short ways and an individual tried to loosen cap, of course hot coolant went everywhere....


I wouldn't think it would be the water pump mostly because they will either start to get noisy, pour coolant out of the seep hole or completely seize all of which you would probably notice. My guess would be that you have air in the system that may be causing the thermostat to remain closed or possibly a bad radiator cap and/or faulty fan clutch (usually when they "fail" they stay engaged all the time but it is worth inspecting. I was taught to ALWAYS drill a small bypass hole in the rim of ANY thermostat I replace. It helps to gradually open the thermostat during warm up and if the thermostat fails to open, there is still a passage for coolant to flow. This is a must for any GM vehicle.
