Question about 1999 Ford Ranger SuperCab
What are the steps to replace the heater core on a 1999 ford ranger xlt?
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. .
