I have a 1992 gmc sierra with a 350 rocket 5.7L automatic 4x4 truck. I just replaced the thermostat and made sure the anti freeze was full. But it still won't throw heat. And after I replaced the...


It's running cooler because the thermostat is opening too soon. As far as the heat goes, let it warm up to operating temperature, turn on the heat full blast and feel the temperature of the hoses going to the core.
1- both cool- engine not reaching operating temperature or the system needs to be bled of air
2- one noticeably cooler than the other- clogged core; you could try backflushing, or replace it.
3- both equally hot to the touch, where you can barely touch them- everything is good on the liquid end- look at your blend door in the heater box.

Heater isnt blowing warm air in 2003 grand caravan


Assuming the radiator is full of coolant, you are describing a faulty thermostat. The thermostat is closed when the engine is cold to restrict coolant flow until it warms up.

I have a 1994 Dodge intrepid 3.3 engine Just have New Radiator, Water Pump and Therma stat placed in car. However the Car kept leaking Fluid out of The coolant tank. My mechanic fixed that by Pressurising...


1) Your car should have a thermostat regardless of what your mechanic says. Fuel injected vehicles run better and more efficient at proper temperatures. So re-install thermostat properly before step 2.
2) Did the mechanic make sure the heater was on high temperature and blower on when he re-filled the cooling system?
Maybe not. So start engine when cool and rad cap off. Fill rad about an inch from the top and let the engine run up to normal operating temperature and keep an eye on coolant level in rad and keep it topped up as it's running. Rev the engine slightly for 5 seconds or so every once in a while to help with flow and pressure to make sure coolant is getting to and through heater core. Keep observing flow in rad to make sure it's good, when thermostat opens. You won't see much movement until thermostat opens at normal operating temperature, then you should see flow in rad and shortly after, rad fan should come on.Leave rad cap off and heater on until the rad fan comes on and off 3 or 4 times to make sure all air is out of the system. Then, make sure rad is topped up, put rad cap back on and fill return bottle to proper level. If that doesn't cure your overheating, then something was done wrong, or you have a possible head gasket problem but proper diagnosis should be done by a competent mechanic. What was the car doing initially to warrant these repairs, overheating?

Heater puts out heat only briefly then blows cold


Check that the coolant level in the radiator is full. Check that the engine has a working thermostat and is reaching temperature. Often if the thermostat is faulty or has been removed the heated will warm whilst at the trafic lights then cool off as the car is driven. The heater core on an older vehicle especially if it has not had coolant in it at some time can become blocked. You could pull the heater hoses off and back flow the core with a hose to flush it. Also check that the heater tap and vent flaps are working properly. If this has been helpfull please vote Jeff

In cold weather it take forever for the heater to warm the car, I can start it then let it run for a half an hour and then drive 30 miles and still is not warm enough


Could be a faulty thermostat not letting the engine come up to proper temperature...also low fluid level could cause fluid to not circulate through the heater core.
Verify operation of thermostat, verify coolant level.
More info would be a help.
Take care.

Heater only blows luke warm air even after driving it for half hour. 1994 isuzu rodeo


Have you changed your themostat to a winter temperature range. If so it may be faulty - stuck open. Remove rad cap when cold and start eng. - (be sure rad is full) water should not start to circulate in rad until thermostat opens at its designed temperture setting as seen through rad opening.

No heat air is blowing cold


First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced.
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is worm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest to flush the heater core.

Heater blows cold air from top vents after running for 1.3 hours


Sounds like you may be able to fix it by flushing your antifreeze and back flushing the heater core. Some car owners cheep out and put stop leak into the antifreeze, others dont change there antifreeze at all. Both are mistakes.
