Heat quits and becomes cold once truck reaches

Heat quits and becomes cold once truck goes over 210. I have circulation, new waterpump, antifreeze. Temp used to run at 210 now running at 230/240 consistantly and that's when the heat starts blowing cold.

    Im not losing any fluid and at this point have not checked the thermostat. I was thinking that might be the problem but weather hasn't permited me to get under the hood. Mainly looking for some clarification on whether the thermostat was the problem since I do start out with heat. As soon as I get a clear day to check it though I will. Thanks.

    are you losing any fluid? And did you check your thermostat to make sure it isn't frozen open?

My heater works fine and blower works fine as long as the truck is moving, but if stopped or stop and go for more than 10 seconds the air goes cold. Ideas?


could be low on antifreeze. at a higher rpm it will produce heat. but at an idle it cannot circulate the antifreeze properly. check it and fill to proper level. hope this corrects your problem.

Rad. has small hole in it. nearly over heated this morn, could only get one gallon of anti-freeze, it was two more gallons low. would this cause the heater not to heat??


Yes! When a car runs low on antifreeze, problems occur. When antifreeze levels get low enough, a car begins exhibiting enough signs that prompt its owner to have it checked.


Low antifreeze in a car engine typically causes its heat to quit functioning. This symptom is normally only noticed during the cold months, when a driver relies on the heat to be comfortable in her vehicle.

Ive got a 98 chevy k1500 with a 5.7 vortec the heater blows out cold air.. and the temp gauge goes sporadic going to 260 back down to 120 then stays steady at 210 then back to 260 then back down... ive...


You may two problems and one symptom. you may have a blend door problem that is not allowing air to circulate threw the heater core. also you may have a bad connection or weak coolant temp sensor showing you erratic readings and it may have nothing with the heat in the vehicle. you need to eliminate or separate the one of the the problems to diagnose your one symptom.

95 Ford is making a thumping sound and the car smells of antifreeze after warmed up. Makes same noise after car is parked and shut off. I suspect it is a bad water pump.


Good Evening, What sounds like is happening could range from a thermostat being stuck shut or a waterpump not circulating the water and your getting the air hammer of the water boiling in your car. First thing to check is your antifreeze level when cold to be sure it is full. Once you know it is full check the thermostat because it is an easier thing to check then suspect the waterpump if the thermostat is not stuck shut. Let me know how it goes.

02 stratus with the 3.0 liter in it, noticed the heat was getting weak, then changed the thermostat and now theres no heat and the coolant level is full, please help


New thermostat may be faulty. May be stuck open. Remove rad cap and with rad full and eng cold - start vehicle. The coolant should not circulate until eng reaches design temp of thermostat. Let me know if this helps you.

1996 cavalier overheating. I changed thermostat but seems like its not opening. Lower hose is cold but fan turns on. any ideas


Your next test should be checking the health of the waterpump. Even with a bubble in the cooling system, the bubble should not take up residence in the waterpump cavity and should pump some. Look for activity in the radiator after things have heated up. Do you see any circulation? If not, the vanes might have rotted off (rare problem). Before doing anything else, try to thoroughly clean the system, and replace the fluid with just water for further testing. I don't know how well the car has been cared for, so if nothing has been done to the cooling system since it was new, try taking the bottom hose off and look for sludge that has gathered there. Clean. Short of all that, disassemble the waterpump and look at it. After you've found the problem, of course replace the straight water with a mixture of water and the good stuff. (No straight antifreeze. More is not better because antifreeze is designed to work with water. Straight antifreeze has poor thermal conductance.) Good luck.

1993 voyager New themastat, new water valve, have heat sitting still, in motion cold air, can stop and rev. up motor get heat again. Suspect autozone (made in china) waterpump.


the problem might be the water pump but unlikely unless your engine temperture gage spikes, the problem might be your heatercore. it is a small radiator in your car to heat up the air, they become clogged but dribre in your antifreeze, you should try cleaning it out first before replaceing anything

2002 Chev Cavalier 2.2L Engine overheating


Did you let engine run from cold after refill, with rad cap off & heater on (not defrost) until the engine reached operating temperature and rad fan came on a few times? If not, try it, you may just have an air lock, provided your sure thermostat is correct one & back in correct way. Rev engine slightly every once in a while and hold it there for approx 10-20 seconds to help burp the air out & increase circulation to heater.
