    I'm trying to figure out where the heater core lines are so I can flush system?

  • brody_hummer Dec 23, 2008

    the air that comes out is like between cold and warm. i think my temp gauge is workin but not real sure. cars not been overheating.there is a little change in the temp but not much at all. coolant lvls are rite and its been like this for a while. not really checked the hoses to the heater core... pretty sure they are fine bc ive not had ne antif. leaking.

    is the temp gauge reading correctly, when you switch from hot too cold first do you feel any change in the temp? secoand do you hear a door opening our closeing?

    Is coolant level in rad up to where it should be? Any warm air at all? Did this just happen recently, or has it been that way for quite a while? Hoses going to & from heater core at firewall both hot to touch when engine up to operating temperature?

It could be a low coolant level or stuck thermostat or maybe even a clogged line you can try changing the thermostat or getting your radiator flushed out at like jiffylube or a place like that

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air

If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

My 99 chevrolet monte carlo z34 heat is not that hot and air works for defrost but not dash vents?

check radiator fluid level it take hot radiator fluid to pass through the heater core to produce the heat in your car VIA the fan. also check or replace your thermostat it could be bad and stuck in an open position thus radiator fluid not getting hot, no hot fluid no hot air
the other problem sounds like a duct hose under you dash has come loose locate and reattach.

I just replaced my 3.4 liter motor in my 2004 monte carlo and I need to figure out why the other motor over heated and blew a head gasket. Before I replaced the motor the heater was blowing cold air and...

a little tip is to "vent" the topmost hot hose whith the engine running to clear any trapped air in system.....loosen the clip,whilst under pressure,wear rubber bloves cos it bloody hot.......

Heater went out

If the fan is still blowing air through the vents, but the air won't get hot, you probably have one of a few problems. 1. Your coolant level is low. Top it off. 2. Your Thermostat is stuck open. Replace it. 3. You have a leak or clog in your heater core or the lines leading to or from it. Replace them. Good Luck.

Heater Blows cold air

You could have a blocked heater core. Check for two heater hoses running into the firewall in the back of your engine. They should be together and about 5/8" in diameter. If one is hot and the other is cooler then your heater core is blocked. Unhook both hoses and use a garden hose to back flush. Be sure to catch the coolant and dispose of it properly.
