its not that hard,it took me about 4 hrs to remove and install a new one you do not need to remove the dash,just a little tight to get a socket in there a number 7 socket is all you need. good luck
If one is rusted you might as well replace them all and that requires removal of the engine
You have to drop the steering column and pull the dash. Then after locating the heater core case below windshield you have to cut out a piece with a Dremel. After replacing the heater core you have fun putting everything back together..(use plastic weld to seal the case back up).in other words don't do it yourself it is a huge pain.
my 86 is about the same and i took out the screws of the glove box and started on the dash board screws then loosened the bolts on fire wall which is the heater core back, the bolts on the right i had to cut off with a mider saw very rusty. take off the cable under the hood left side and pull heater core box out disemble and put in a new core for 26 dollars and redoo.
Heater core should be behind glove box. Remove glove box and screws( approx. 8) that holds cover in place. Pop hood and look for two hot water lines running into firewall at that location(passenger side) Remove lines by loosening hose clamps(advisable to replace) Remove heater core from inside and replace.
Sounds like 1: the heater core was never fixed or 2: the coolant system wasn't filled and purged properly. if the car is loosing coolant and overheating i would check the heater core. if its low on coolant or has air in the coolant lines you wont get any heat either.
NOT AN EASY JOB all of the av ducts have to come out from under the eash. Get a manual on your car and it should have pictures.
No. Only the right rear pulls.
86
Yes.
It sure will, as long as the engines are the same
I have an 86 and it has the A200R4 trans. If you have an overdrive position on your shifting column then that is what you have, if you only have a 3 speed then you probably have a turbo 350.
take the fan out and behind the fan there should be a chip.
