SOURCE: heater core replacement

It's one of the easiest cores to replace that I have encountered. Disconnect heater hoses at firewall. Probably doesn't matter about hose placement, but I always mark them just in case. To remove the fiber cover under dash, take a flat blade screwdriver and pry out the center pin of the expansion clips that hold it in place. There are four 5/16 head screws that hold the bottom/drain tray cover. Core will pull through the firewall and then down. You may have to silicone/glue or replace the foam seal strips on the new core. Before you install the core, check the distance between the inlet and outlet tubes to ensure they match the openings in the firewall. This saves time. It helps if you have someone on the outside to guide you when stabbing the tubes through the firewall. Replace bottom cover. You may have to hold one of the tubes when reinstalling the first hose to the core. Replace any lost coolant and check for leaks prior to reinstalling the fiber cover. If the cover seal is in good condition, any leak should drain through the firewall, otherwise it may leak inside cab. .

SOURCE: 2002 DODGE 2WD HEATER CORE REPLACEMENT

first off, disconnect your battery for at least 30 min before touching any plugs or harnesses. next, bleed your A/C and disconnect the quick connects that go inside the firewall. drain your coolant, and disconnect hoses from firewall. note a certain bolt with nut on it that is going to the inside of the firewall, you'll need to take that off when you get to the airbox inside the truck which houses your heater core. next, take off the pillar handles next to the windshield, then pop off the plastic dash panel with defroster vents. there are a few bolts up there that need to be taken out all the way across. next, take off your glove box. remove plastic below the drink carrier. there are 2 bolts there on left and right once you remove the plastic. there's a yellow or red AirBag plug which you may or may not need to disconnect later. next, drop down the whole steering wheel column. 4 bolts I believe. look up under there on both sides, you will see a 2inch piece of tubing that goes from each side of the truck. your dash and everything you see in front of you is connected to that tube. find on each side of the truck where that tube is mounted to the body with brackets. There are 2-3 bolts on each side I think. When you get those out, and the steering wheel is sitting in the seat or on the floor, the whole dash and panel should tilt and lay on the seats. there are wires from your a/c controls and radio which you'll have to disconnect and some various other wires as well. I also think you'll have to disconnect a harness plug with bolt in it on the drivers side. (white) after you've done all that and don't have the dash and panel in a bind with wire hangups you can now get to the air box. I don't remember how many bolts, but don't forget the one in the engine bay going to it also. get the box unbolted, then roll it up, remove 2 clips holding the heater core in, replace heater core and do this whole process backwards. Hopefully you didn't lose any screws or bolts. charge your a/c, replace coolant, make sure all plugs are connected before connecting power. Should save you $400-$500 in labor.

Flush heater core on 2009 ford ranger


if your just doing the heater core you can clamp off the heater hoses to the core, disconnect them from the heater core and run water through it both ways. if its real bad connect spare hoses to the heater core spigots and pour CLR into the core until it is full(coming out other hose) block off hose so the core is filled and let sit. then flush out again until water runs clear. if this won`t clear it then it will have to be replaced.

2002 Ford Ranger Extended Cab Heater Core Replacement


Not an easy job. Drop the steering column and remove the dash first. Then remove the plenum. Core is between the plenum and fire wall. Get a manual. Your saving hundreds doing it your self. 30 dollars for a manual is worth it.

Are the heater core hoses hot? If so then you will need to replace the air temperature control blend door and its electric actuator. If this is the problem you can speed the repair time (10 hours) by using a kit called a Heaterbeater. You can buy the kits on eBay.

Heater core


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.
Heater Housing
  • 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.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.
