Hello,
Well i was actually working on one of these today. It was an 84 though, not sure if it would be the same, but here goes.
First - i took off the bottom panel on the pasengers side. about to screws.
Second - You have to take off the glovebox. start by taking off the striker on top with a 10mm you can also sue a scredriver but they might be too tight and you just might strip it. then there are 4 screws on the actual glove box. after those are taken out the glovebox is off.
Third - take off the harnesses near the computer. ther shopuld be there lined verticaly in a plug housing type of thing. theres a top one then empty slot then black one then another white one. after unpluging remove the female ends of this harnes from the housing and remove the housing. that little housing take a little room but gives enough space to take out the far right component.
Fourth - far right component needs to be removed first. unplug the harnesses that are hooked to it a. there are thre bolts 2 at the botom and one up too(this is when you nee to be laying on the seat upside down or just take out the seat more comfortable)
Fifth - AC Unit. unplug about 3 or 4 small harnesses and there are only 2 scres one at the bottom and one at top. Remember to disconrct ac lines from engine bay side and make sure that there is no freon in there.
Sixth - The fun begins with the heater unit. removal of the radio is in order.
a. remove the radio bezzel by unscreing for screws 2 at top and 2 hidden by the ashtray.
b. the the radio itself ther are four screws. 2 are looking at you at the bottom of the sterio unit(10mm) and to are up top facing down. then desconect the harnesses off the radio and now your cookin.
c. The heater core is held by for screws. 1 on each end of the heating unit and 2 behind where the radio was. (remember to unhook heater hoses, have fun) now remove some of the vents there the ones that give you the room to take out the heating unit. soe vents do have screws you need to find in order to remove. now slide the heater torwards the rear of the car and slide over to passenger side and slip through where the glove box was. your done HAVE FUN I KNOW I DID.
to reinstall do everythig backwards. if you have further questions contact me at my e-mail which is nvmy95delsol@Yahoo.com i will be glad to answer them
To change the heater core in a 1986 Toyota Supra, first disconnect the battery and drain the coolant. Remove the dashboard and climate control assembly to access the heater core housing. Disconnect the heater core hoses from the firewall, then unbolt and remove the heater core itself. Install the new heater core, reassemble the housing, dashboard, and reconnect the hoses, ensuring to refill the coolant before testing the system.
It's in the heater core housing.

Reconnect all components, refill the coolant, and check for leaks.

how to change heater core in 98 suburban
To change out the heater-core in a 1986 F-150, you must access the old heater-core through the glove box. You must remove the glove box by removing the screws that hold it in. Once this is accomplished, you must loosen the clamps on the hoses that are connected to the old heater-core unit. Then remove the hoses from the old heater-core and slide the old heater-core out through the opening where the glove box use to be. Install the new one using these instructions in reverse! Presto...installed! Mechanic Man
