A
heater core transfers heat from a 1994 Ford Ranger's engine to the
passenger compartment by running hot radiator coolant through a
serpentine of tubing. Air blows past the hot fins of the heater core
and into the truck cab.
2.
Attach a 3/8-inch interior diameter hose to the drain outlet on the
bottom rear corner of the radiator on the driver's side, and place
the bottom end in a resealable plastic container. Turn the drain
valve (located above the drain outlet) counterclockwise with a pair
of pliers. Drain the engine coolant into the resealable container,
then close the valve by turning it clockwise. Remove the hose from
the outlet.
3.
Loosen the hose clamps on the radiator hoses where they attach to
the heater core on the firewall. Remove the hoses.
4.
Unscrew the screws holding the underdash cover in place on the
driver's side of the passenger compartment. Remove the underdash
cover. 5.
Unscrew the four screws on the cylindrical heater core access cover
and remove it. Remove the heater core by pulling it down and toward
the rear of the vehicle.
Replace the unit with a new heater core.
6.
Reinstall the heater core access cover and screw in the retaining
screws. Replace the underdash cover and screw it into place.
7.
Replace the radiator hoses on the heater core in the engine
compartment. Tighten the hose clamps. Add coolant until the level is
between the minimum and maximum marks on the reservoir.
8.
Replace the battery cable and start the engine. Check the system for
leaks.
The hoses running to and from the
heater core must be removed from the engine compartment, but the
core itself is accessed from inside the passenger compartment, on
the driver's side next to the center console.
1. Turn off the
engine, open the hood and remove the battery cable from the negative
terminal. Make sure the engine is cool.
