I may have to replace the heater core on my 1990 Celebrity. Done from under the hood, or inside the car, under the dash? How difficult is this?

View 8 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 RepliesI have a 2008 Hyundai Santa Fe . Since January 2013 I have had the heater core replaced 3 times. The repair shop has done the last 2 at no charge to me. The dealership ran a diagnostic and could find no reason for the repeated heater core failures. I feel there has to be something going on with the car that is causing the heater cores to keep failing. When the original one started leaking I had around 70,000 miles on my car. I bought it new.

View 5 RepliesHave a '02 f150 and thinking the heater core slowly dieing. Have noticed for several weeks a nice line of water leaking onto the passenger side floor. Do you have to take off the entire dash to get to it? Will be doing replacement myself as the dealer or shop would probably kill me on labor.

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 3 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.
