Where is heater core temp sensor located on 2002 sable 3.0

SOURCE: where is the heater core

Hello- on most VW models the heater core - sometimes called a matrix - is buried deep in the dashboard area. It is renowned as being almost the most difficult thing to access as car makers start a production line by putting the heater core on a stand and then build everything else around it.

You would have to remove the steering wheel, then the dashboard... and I would check all other possible faults before trying to replace it. What are the symptoms which make you want to find it?

Let me know. Thanks, D.

Radiators do not "go out". They leak or they don't... that's it. You wasted money changing a radiator if you aren't loosing coolant. The thermostat (~$10) is all you needed to change.

Hi

The first thing to check is the coolant level and to insure the thermostat is working. Usually just putting in a new thermostat is the best thing to do. When you have already replaced it then make sure there are no air bubbles in the cooling system. Here's the procedure for bleeding the cooling system....

Loosen the air bleed bolt in the thermostat housing, then fill the radiator to the bottom of the filler neck with the coolant mixture. Tighten the bleed bolt as soon as coolant starts to run out in a steady stream without bubbles.

With the radiator cap off, start the engine and let it run until warmed up (radiator fan comes on at least twice). Then, if necessary, add more coolant mix to bring the level back up to the bottom of the filler neck.

Put the radiator cap on tightly, then run the engine again and check for leaks.

The next thing to check is the Heater Control Valve. With the heat selector on HOT, the valve should be open. Feel the heater hoses, they should be equally hot on both sides. If not, the valve is not opening and needs to be replaced.

If after this you still have no heat, you need to check the HVAC controls. There is a cable that goes from the temperature selector switch to an air mix door. Check to see that it is still attached on both ends and not kinked. Its been seen many cables bend and distort at the air mix door.
