Hi! Yes its doable though this requires experience. As a novice I strongly suggest that you get a copy of HAYNES or CHILLTONS manual to guide you. This will be available on the local bookstore or auto parts store. Hope this helps and thank you for using FixYa!

How to replace heater core on 2009 dodge journey


Heater cores can be very challenging and time consuming to access. I suggest you don't even start until you have a good shop manual for that model, a 1/4 inch drive ratchet with short and long extensions and 1 or 2 u joints and lots of patience working in tight areas

Antifreeze leaking on inside passenger side of 1994 GMC suburban


It sounds like you probably have a leak in your heater core. Replacing a heater core can be a difficult job. If you decide want to try it I suggest you get a shop manual to help you out. I can give you a relatively easy temporary fix that will stop the leak until you have more time to fix it or you can take it into a shop to have it done. The down side is this fix will temporally disable your heater. Wait for the engine to cool. Open the engine compartment and look all the way in the back between the engine and the firewall. Find the 2 heater hoses that pass through the firewall. They should be about 1 inch in diameter. Undo the hose clamps and disconnect them from the firewall. Get a short piece of metal tubing about the thickness of the inner diameter of the hoses. Use this metal tubing to connect the heater hoses together and clamp them using the two hose clamps. Now the antifreeze that would normally circulate through your heater core will instead circulate through this loop and not enter the passenger compartment. If you can't find a short piece of metal tubing to do this fix you can completely remove one of the heater hoses. Then take the other heater hose and connect it to location near the engine where you disconnected the first hose. Save the first hose so you can hook it up later when you do the more permanent fix. Make sure to position all hoses such that they aren't resting on any hot surfaces. I hope this advice helps you out.

If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.

  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

Does a replacement of the heater core diagram exist? how do i replace the heater core. I have a mechanical background.


Most Jeeps require removal of the dash board to accomlish a heater core replacement. It isn,t really hard to do, but is a hundred times more difficult if you don't have access to A/C evac/recharge equipment. The service manuals give step-by-step instructions, usually with pictures, on how to do this. If you want GOOD, RELIABLE information on your particuler model, you can purchase a one year, single vehicle subscription of AllData for $26.95. Click the link below to go to AllData.

It's not free, but it is the same information used by professional shops and costs a lot less than paying shop labor. (The usual labor time for replacing heater cores in most Jeeps is 6 to 7 hours.)

Only drivers side heat is blowing cool air, passanger side is working fine. are there two different heating untis for this car since it has two separate controls? could it be a sensor or a flap? flap...


No there is one heating unit that has a flap that is controlled by the passenger side vs. driver side cooler or hotter knob or setting, if it's like my Cadillac. It's called a blend door. There is only one heater core that feeds the two separate sides.

Will have to pull the dash, and inspect the vacuum lines and cables.

Replacment of heater core on 01 chevy S-10


Have replaced my heater core in my 2001 regular cab 4wd in december 2009. Had to pull the complete dash including the complete metal dash behind the dash that you see. Also had to remove the right passenger side inner fender well to acess the remaining two bolts that hold the heater core cover to the firewall. Its an insane job to do but the repair shop books call for 9 1/2 hrs to do the job. I'm not an expert but this is what it takes.
