I need to replace my heater core in a 1985 El Camino

SOURCE: need to replace heater core
The heater core in 1985 was still accessed from the engine compartment. After you drain the cooling system, disconnect the heater hoses. They should be 2 different sizes so take note of which one goes where. Unplug the electrical from the case and then unbolt it. Pull it off and replace the heater core.
If you have A/C then it is a little more complicated. After you remove the heater hoses there is a retaining bracket and ground strap that have to come off first. Then take off the rubber seal and screen. The right wiper arm needs to come off next followed by the diagnostic connector, high blower relay and thermostatic switch. Now you can unplug the electrical from the case and the top cover and screen and take the heater core out.
Once you have it back together, when you go to bleed the air out of the system, make sure the heater is turned on maximum heat and the fan is on high. This will ensure that coolant goes through the new heater core. Hope this helps.
