Sounds like a few things it could be; A; is the water pump working properly, B: is the thermostat working properly (does the car come up to operating temperature around 195 degrees and remain there) C: is there any chance that maybe you are low on coolant/antifreeze, check both radiator and overflow container. D: Last of all is there any chance you may have installed the wrong head gasket or had it up side down? (if all else checks out i would assume that this is your problem.) NEED TO ASK YOURSELF WHAT CAUSED THE HEAD GASKET TO GO IN THE FIRST PLACE, BECAUSE IF YOU DON'T RESOLVE THAT ISSUE THAN IT WILL ONLY BE A MATTER OF TIME BEFORE IT HAPPENS AGAIN. Hope this helps

Maybe it's your thermostat. Take it out and put it boiling hot water and see if it opens or not.

SOURCE: 93 ford festiva heater only blows cold air.

The heater only blows HOT air when set on defrost or floor settings. If you have the lever set for vent, only cold air will come out. Check to make sure you set the controls to floor or defrost. This is standard for all Festiva's.

SOURCE: heap of white smoke on startup but not always

White smoke usually occurs when there is not enough heat to burn the fuel. The unburned fuel particles go out the tailpipe and typically produce a rich fuel smell. It's not unusual to see white smoke in the exhaust during cold weather until the engine warms up.

Faulty glow plugs or control module can cause white smoke on engine start up.

Low engine cranking speed may also produce white smoke.

If white smoke is still visible after the engine has warmed up, the engine may have one or more bad injectors, retarded injection timing or a worn injection pump.

Low compression or air in the fuel system can also be a source of white smoke.

SOURCE: heater blows cold air. I have replaced thermostat,

Not an expert by any means, but i know my ranger.. I had a small leak at the top of my radiator that still cooled the engine but didnt have enough pressure to get to the heater. The heater hoses travel up over the engine and just were not gettin anything to my heater core. That or make sure the heater control valve is operating.

How to burp a 2009 Pontiac G6 GT 3..5L V6


Many modern cooling systems are best filled using a vacuum filler - a new fangled tool that sucks all the air and remaining coolant from the cooling and heater system and then allows atmospheric pressure to force coolant into every corner of the system.

The traditional method of bleeding the cooling system is to disconnect the heater hose from the cold or return side where it connects to the engine (engine running at a fast idle, heater switched to hot) and be ready to reconnect as soon as coolant flows.
Other hoses sometimes also need to be bled and sometimes removing the temperature sensor can also help.

The air lock is primarily caused by the traditional thermostat jiggle pin being deleted though sometimes this function is replaced by the degassing system.
In the case of a really stubborn air lock or a recurring air lock it is worth checking for a degassing blockage.

Lost all coolant fulid smoke coming from bonnet no over heating puddle of fulid I filled it up again started car left for 5 mins only slight drip hitting floor so I attended 2 drive home


You have a split in a hose, or a loose hose, a cracked block, a loose freeze plug, a loose block heater, or a failed cylinder head gasket.. When the coolant heats up it expands, and pressurizes the system, the small drips soon becomes a spray. You just have to find where it is coming from. Do it in daylight with a good flashlight with the car on your driveway.

Also, you know there are two places to add coolant, the radiator, thermostat housing or cooling system itself and also the coolant reservoir.

Heater slow in warming and blows cold air after warm air. Gauge has started fluctuating.


Check for low coolant level. If coolant level ok, possible headgasket failure and further diagnostics will be required to confirm a headgasket failure

Why 1995 gmc vandura only blow hot air while driving but sitting still cold air


Low coolant level.... restriction in heater core or vacuum problem with hot/cold blend door would be what to look at. Worst case scenerio would be headgasket issue but unlikely

My 1999 ford windstar is only blowing cold air and no heat


possable problems:

1. coolant leak (level too low to fill heater core)
2. headgasket leak forcing the coolant out of the overflow.
3. stuck thermostat.
4. bad water pump. if the impelers are broken, coolant wont flow.
5. HVAC malfunction. system may think you selected cold or is unable to move diverter. maybe a fuse,solenoid or vaccum leak? (hvac controler uses vaccume controled soleniods)
6. airlock. if you have resently changed your coolant, you may need to repeatedly squeeze the heater core hose to help force out the air.

I have new headgaskets and thermastat no heat in car and still over heating on my 99 subaru outback


If everything was done just right the problem might be air trapped i the system. Add the coolant slowly while running and feel the heater hoses. Sometimes just mild pressure on the heater hoses will push out the remaining air. Don't forget to open radiator bleed screw on passenger side. Makes it much easier. Good luck and have a great day.

Engine overheats when heater pipes connected


I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

Coolant leakage from above where the radiator hose enters the intake. Cannot determine exact location of leak because of all the wires etc at air intake. Is there a heater hose or some other connection...


this windstart come wiht some metal heater lines hard to see you might need a mirror, and a flash light, also when the van is cold and the coolant full go with another car to autozone, and they have a loan tool service, get a presure tester for the coolant, and create some presure to it while you look for the leak, be sure not to add more tha 15 psi.
