SOURCE: 96 ford crown vic over heating

it seems you have to seperate issues here. fiirst let's start withtthe over heating. you stated that you have replaced the pump,thermosta,fan,clutch,all the hoses, and core. now my question to you is did you route the belt so it's circulating like it should? is it steaming out from under the hood? to be quite honest the vehicle should not even be close to overheating after driving only 3 miles. there is a possibilty that you have a bad sending unit for the temp if it is not steaming out from under the hood. your upper radiator hose is hot this tells you that the thermostat is operating as it should. the fan should be turning clock wise as you are looking at it from the front of the vehicle.when you fill the system with coolant make sure that you have the heater on high and to the hot setting. check to make open sure you have plenty of coolant and that the radiator is free of dirt and bugs.. now as far as not having anyheat in the vehicle check the fuse for your climate control. look under the dash and make sure you hooked all the cables for your fresh air door and blend door. when you changed the core did you connect the hoses in the right place?after you have checked all the hoses and the coolant is as full as can be and the heat is turned on to max ,keep the radiator cap off and start the vehicle wait for it to get hot check the upper radiator hose to see when the thermo stat opens you should see that the coolant should go down in the radaitor. do these things and check back with me on the results...please rate this help...thanks

SOURCE: 97 f 150 runs hot for minutes then runs ok

It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

first, try sqeezing the hoses several times too get any air out of them. second, you may have put the thermostat in backwards, so it is not going to open and let the coolant flow thru.you could ruin your engine instead of your radiator. good luck

SOURCE: The heater only blows luke warm air. Just replaced

Hello...

One of 3 things could cause this, that I know. The thermostat has been installed backwards. The water pump broke soon after install. Due to it being a rebuilt one. And a small clog in the heater core. All of these things are easy to fix.

Good Luck...

You just might have an air lock. Try bleeding the system from the heater hose at the firewall. Losen one hose a little, and at operating temp. open slightly to let air out. You will lose some coolant, but just refill the rad. Now, both hoses should get hot.

I only get like warm air on floor but no heat anywhere else. 2001 ford f150


Either your heater blend door is failing, your core is plugged, or you have poor coolant circulation. checking the temp of both heater hoses will rule out the core usually. (Warm engine, heater ON, both hoses should be HOT and near same temperature). If 1 hose is hot and the other cold, your core may be plugged. If both hoses are HOT, and still no heat inside, your heater box is likely not directing the warm air properly on the interior. If neither hose is hot or warm, and heater is ON, your heater control valve should be checked to make sure it is flowing coolant to the heater.

If all THAT seems to pass (heater valve definitely open) an d still low or not heat inside and both hoses the same, your water pump may not be making enough flow to feed the engine and the heater. Typically if this is the problem, holding the engineat high rev (3000+) for 5-10 minutes will cause the heater to warm up mostly, and then dropping the RPM to 1000 or 1500 you will feel it cool off rapidly. If that is the case, you will need cooling system repairs.

Check the thermostat. It's almost like a "float" that allows coolant to pass through a hose. If it gets stuck, you have heating issues. Since yours seems to fluctuate, I'd bet it's a thermostat about to go. Fortunately, it's easy to fix and inexpensive.

1993 ford escort heater blowing cool


heater core cloged, get car hot check heaterhose going into heatercore should be two inch thick hoses going into the heatercore, underhood against firewall pasenger side, after hot while running heater on, chech to see if both hoses r hot, if one is cold,that means there is a restriction in the heatercore, sometimes on older cars there is a external valve run by a vaccume hose, or cable, thats fixed in with the heater hoses , sometimes this valve jams and can be manually switched.

Check your heater hoses..If one is hot and the other is cool or luke warm,,then the heater core is clogged..I know its hard to get to ,,but if its clogged sometimes you can take the hoses off,,and run a garden hose through it and flush it out..

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

Are you sure that the spring side of the thermostat is toured the engine/ look for a bleeder near the top highest spot in a line or hose that may be able to release the air it may even be near the water pump side.on some water pumps for the ford's the pumps will bolt on and look almost the same but the fins on the impeller are the opposite.clock wise instead of counter clock wise or vice vars. you my wont to check with your parts supply store to see if that is possible.hope this helps give you some ideas.feel free to ask again if you would like any further assistance.thank you for asking fixya .

No heat in my 97 dakota noticed when motor is warm both of the radiator hoses are cold what is causing this


good day, heater core/coil is leaking antifreeze and needs to be replaced. The heater core works in conjunction with your engine's cooling system. The function of the cooling system is to remove heat from the engine, and it does this for the most part by sending the heated anti-freeze to the radiator located in the front of the car. The position of the radiator allows outside air to blow across the radiator thus cooling the anti-freeze. The anti-freeze is then sent back to the engine. Hot anti-freeze is circulated throughout the cooling system by the radiator and heater hoses. Think of the heater core as a small radiator located inside the dashboard of your vehicle. hope this helps, have a nice day.

sounds like you have a actuator problem or the heater core may be stoped up check and make sure actuator is moving if not replace

make sure both heater core hoses are hot to touch at operating temp if both are not hot replace heater core

and of course check your coolant/antifreeze and insure it is full no water no heat

Heater blows cold air


With the car warmed up,feel the heater hoses,are they both warm/hot near the firewall in the engine compartment?If they are both warm/hot,then the heater core should have circulation through it and it may be a "blend door" issue in the heater a/c assembly.If they are not warm/hot then the heater core could be dirty and plugged up and needs to be flushed.
If the above does not help,a drain and vacuum of the cooling system and vacuum refill will remove any trapped air.
Sometimes,clamping off the top rad hose and holding the engine rpm at 2000 rpm will force trapped air out of the heater core.(Watch temp gauge when trying this)
Lastly,a NEW thermostat doesn't mean its working correctly.
