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. .

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.

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.

The thermostat could be stuck open.I would flush the coolant system with prestone super flush then replace the thermostat just in case the heater core is partly clogged.

How to replace heater core on 1990 ford ranger


Remove the glove box door. Behind the glove box there will be a big plastic panel that contains the evaporator and the heater core. The heater core will be copper. That is the one you need to remove. Do not try to disconnect the aluminum one. That is for your AC. Remove the two heater hoses on the outside of the firewall that connect to the heater core and it will slide right out.
