Question:
I just had a new heater core installed because I had a coolant leak in my 2000 Sunfire. Before the car went in the heater was working perfectly. After the repair, I can only get warm air from the heater, it is not nearly as hot as it used to be.or not nearly as hot as our other car or my neighbours.
The garage that installed it, claims the heat is normal, but it is definately not. After some research, the only explanation I have found is there could be some air in the line. Any suggestions??

Does any1 knows how to change the sensors (radioter) in a 1999 ford countor?
Could be one of the air deflectors in the heater box. If they weren't lined back up properly it could be letting cold fresh air in instead of re-circulating the warm air in the car. It can be a real pain in the *** to get those right these days. Especailly if they had to seperate the heater boxes into halves to get the core out. I've had to do this before and it's very had to get all that stuff to line back up and work properly again.Is just the battery fried, what else could be wrong?
EDIT: Whatever you do don't do as ca_surveyor said and disconnect the heater hoses from the water pump while the engine is hot and has been running. This would cause a massive release of steam and pressure and would burn you severely! If you want to check the flow, put the clear loop hose on first and run the engine up to operating temp and observe the water flow. Then, after the engine has cooled, move the clear hose to the output side of the heater core and plumb the other side of the core as it was before and test the flow again. You will want to be sure to get a clear hose that is rated for the atleast 200+ degrees. The water at operating temp will be atleast that .
Why won't my high beams go off even when I turn off the engine on my 97 ford crown vic?
Again,
Good Luck
I have a 1994 Chevy Silverado, I need a new catalytic converter to pass smog does anyone know...?
i would guess one of two things.did they change the thermostat? if so it may be of a lower temp range and that could be the problem or they could have the two hoses switched backwards lots of people dont realize that there is a difference ...thats the 2 things i would check.vapor lock , take the rad cap off and start the engine run it for a while and check the heater is it as hot as before , then repace rad cap and go driving
Switching From Conventional Oil to Synthetic?
OK.. sounds like you need to check your flow.. if you can find some transparent plastic pipe this will make it easier if not its going to get messy .. try the followingI'm taking my car to a garage tomorrow..there is oil in the antifreeze . How did that happen??
Fill up your radiator and run the car for a few minutes to get the thermostat open.
disconnect the input and out put lines from the water pump and connect the clear plastic jumper pipe. If not then attach a piece of garden hose to the output and place it on the ground where you can see it discharge.
Start the car and look at the hose. You should see a strong flow of fluid..
How do I find out if my car has SEALED BEAM HEADLIGHTS or not?
stop the car --- if you used garden hose put water back in the radiator.
Will you still be able to drive a car without a wheel cylinder?
If there was no real pressure (it should be almost like a garden hose), check the thermostat. If it is open then your water pump is out.
If there was pressure, connect the input to the heater core and put the garden hose on the output again, placing the end where you can see it.
Will you really feel a difference in handing after adding a strut bar?
Start the car. Same (high) pressure coming out as you saw going in? If yes then the flow is good. If no then the core has a blockage.
98 Jimmy battery or alternator problem?
Either way, shut down the engine, reconnect everything and top off the radiator.
Next question .. do you have the same air pressure as before. At HIGH pressure you should have a good wind coming out of the vents. if not, then you have some blocked vents on the core.
If any of these are problems take this info back to the garage.\
Who knows something about the new "flex fuel"?
good luck...
