View 6 RepliesI have a 2010 GMC 3500 Savanah van with 6.0 motor. No heat in van. Engine operating temp is normal. Heater hose into core is hot. Hose coming out is barely warm. I am of course hoping for another explanation other then blocked heater core. The truck only has 45k miles. I am ready to backflush , but wondering if there can be any other explanation. A/C works normal.

View 8 RepliesI have a 2000 F-150 5.4L 4x4. I am currently deployed and my wife has the truck. Just yesterday she told me my heater core went out again the only way she knows this is its the 4th time in just over a year. What would cause a heater core to go out so many times in a short period? What should I have my wife do? I do not want to get rid of my truck and I wont be back for another few months.

That is, coolant always circulate through the core, there is no "valve" that turns it on or off.
The HOT / COLD dial opens and closes a door (vacuum operated) that allow air to enter the heater core area?
I thought the air will be flushed out from the heater core over time. Heater works ok, but can hear a sloshing sound.
Does pressing the rubber heater hoses going to the firewall? Other methods? Take coolant tank cap off once in a while?
I drained all the coolant from the radiator and engine. After I fill up and bleed the air from the system. I'm very sure no air inside the engine. The next day I found have air gurgling inside the heater core. Look like have a small leak but I check all the engine, host and radiator no leaks. The last think to think is heater core and heater core host. How can I check both parts? If they leak. How hard to change? Can I DIY?

View 8 RepliesWe have a 2006 PT Cruiser. Within a year the Dodge dealer has replaced the heater core five times. They say it's a defective part each time, but I'm not so sure. Usually the core gets a leak after the car has been driven, then parked for a few minutes. When we restart it the heater core blows sending antifreeze vapor out the heater vents.
View 2 RepliesI just put a heater core in a friends passat that was running just fine, drove it into the shop. I pulled the dash and replaced the heater core and put it all back together. Everything works, starter turns over and all but wont fire. I went over everything numerous times to find anything unplugged but all looks fine. Says something about an airbag fault when you turn on the key. Would this prevent startup? what can I do?
View 6 RepliesMy commute into the office was more difficult than usual because of the fumes pouring out of the vents. I have a 1997 F-150 5.4 V8. should I remove both in and out hoses from the firewall and connect them with a plastic fitting not to risk breaking the aluminum fittings on the motor?(There is an advanced a mile away) OR is it possible for me to remove the in hose from the firewall and remove the out hose from the motor, and run the in hose directly into the motor. Are the fittings the same and can I do that with limited time and tools?
View 8 RepliesI am working on a friends Neon and he been having an issue with constant overheating even through he has replaced the thermostat, the radiator, water pump and related hoses. However, he is missing the cap to the coolant tank and his heater core hoses are blocked, both incoming and outgoing. Could the blocked hoses be causes it to over heat?

View 6 RepliesThe two hoses from the engine to the heater core plumbing at the firewall came off. The plastic piping the hoses attached to became brittle and weak from engine vibration. I tried threading 1/4" pipe threads then installing pipe nipple to which I attached heater hoses from engine-worked for a while then failed. There is very little room to work with between firewall and the engine. I'm curious to see how plastic piping goes to heater core.

View 5 RepliesThe heater on my 2001 ford F150 is not heating. The blower is working, the inlet hose is hot, the outlet hose is cold. Removal of hoses confirms that there is very limited flow through the heater core. I flushed it but got only minimal improvement. However when I back flush (reversing the flow through the core) the flow is great. Here's the question: Can I reverse the flow through the heater core on a permanent basis? It seems this would give the needed flow of hot fluid through the core to allow heating. Is there a problem with doing this?
