Truck doesn't heat while idling

Could be low on antifreeze. The heater core is the highest spot in the cooling system and it may develop an air pocket. Another possibility is the thermostat is stuck partially open and doesn't let the engine warm correctly, watch your temp gauge on the dash and see if it comes up to the middle like it should while idling. If it doesn't, it may need replacement.

How To Replace A Heater Core 1995 Olds Aurora

Start inside the vehicle on the drivers side, remove the drivers side bottom dashboard plastic panels, you'll need to pop out the switches on either side of the steering column to access the 10mm bolts that hold the plastic panel, and steel panel under it. Working directly in front of the console above the floor, by the firewall, will be a black plastic cover on top of another black plastic cover. They are held in by 5.5 mm screws. Once both panels are removed, you will finally see the heater core. There are 2 straps that hold the heater core in place. Remove the 5.5 mm screws that hold the straps to the housing. Now, from under the hood, around the center of the firewall, there will be a rectanglar shaped vacuum box mounted on top of a relay bracket, remove to 3 10mm nuts to move vacuum box and relay bracket out of the way to access the heater core hoses. It may help to, from the inside, push the heater core forward thru the firewall, and then from under the hood, cut the aluminum tubes a inch or so from the heater hoses, a long sharp edge flat blade screwdriver might help. You can do this from inside the car, but watch for anti freeze. Remove the hog ring clamps, vice grips might help, in removing them. Use alot of WD-40, by spraying between the hose and the tubing, use a thin screwdriver between the hose and tubing to break the seal of the rubber hose to the tubing. Remove the 2 tubing pieces from the heater hoses. You are ready to reassemble. I'd replace the clamps with some worm gear clamps, alot easier to deal with.

2003 mercury sable blows cool air when heater is turned on.

Most likely it is a clogged heater core. Have your heater core reverse flushed or your blend door is stuck open.

I need to replace my heater core

The heater core is located above the gas pedal on the drivers side. You have to remove the gas pedal assembly first. Next there is a plastic cover over the heater core tubes held with a screw. Finally release the clamp holding the two aluminum in/out tubes to the core. Push the tubes slightly forward and out of the way. With a little effore it will slide out and the replacement can slide back in.

Hope this helps, James Booth

My heater on my 2001 mercury sable isn't working.. It will blow warm air for about 2 minutes and then goes cold again

I had the same problem with my sable. You need a heater blend door. The one on your car is stuck and wore out. The replacement part costs about fifty-two dollars, labor will be more like about one hundred dollars if you take it to a dealership.good Luck
