I recently installed a new heater core in a 1991 G10 van. I removed the heater fan housing, the heater core hoses, then the compartment came out. After removing the campartment has to be taken apart to replace the core. Alot of work but not all that hard.

How do you change a heater core on a 1992 Chevy Corsica?

If it is like my 1990 Chevy Corsica, I removed the black plastic cover under the center of the dashboard (below the radio etc.) Then remove the screws for the black plastic drip pan; you may need to pull straight away from the fire wall since that is where the drip tube exits. Then remove heater core bracket and screws. [I removed my core to replace the core's cracked hardplastic tubes that also pass through the firewall, with hose and clamps.] {I also removed the glove box to give a little more light and space to crawl under the dash.}

Pull the top off of the black box on the passenger side of truck under the hood. Remove the two heater hoses. Remove the old heater core. Reverse the process. Top off the radiator with antifreeze and check again after a test drive. Enjoy the heat.


How do you change the heater core in a 1993 Oldsmobile Cutlass Supreme?

You must rock the engine foreward to remove the heater hoses. To do this you need to remove the bolts holding the torque struts to the engine. use a prybar and pull the engine foreward far enough to insert the long bolt you removed from the strut through the loop hole on the strut. This will hold the engine. Then you need to remove the sound insulators under the dash board. There is a black HVAC box under the dash, Look for the center floor vent outlet under the dash and remove it. Then You will be able to access a big square cover on the HVAC box. There is something like 8 screws that hold the cover to the box. Once the cover is removed You will find the heater core and the a/c evaporator (looks like a heater core but a little bigger). There is a plate that retains the heater core in the box. The plate is secured by a couple of bolts. remove those bolts, remove the plate, then remove the heater core. When installing new heater core, use petroleum jelly or some kind of grease like white lithium and apply it to the heater hose necks on the heater core to aide installation of heater hoses.

How do you change a heater core on a 1992 Ford Ranger?

You need to remove the black cover under the dash (passenger side). Remove the two hoses/clamps from the engine side of the heater core, which is against the firewall. After removing the black cover (held down by a few screws), carefully remove the old core, being careful not to spill any remaining fluid from the old core. Obtain a Ford heater core from the dealer (precise fit, better than most aftermarket ones). This job is easier than most heater core replacements as you do NOT have to remove the dash or glove box to access this black cover. answer u do need to remove glov box to access the heater core cover to remove glove box is as easy as removing the ash tray there is one screw to remove then glove box will lift out. then continue as first answer said
