How to change out a heater core in a 1996 Mustang Coupe?

Answer 1

I believe it is similar to the placement in a camaro. To find your heater core, look under your hood for a silver canister with silver lines running into the firewall into the interior. I am betting it is located behind the passenger side glove box. Should be about 3 nuts to remove glove box and use a flashlight to see how to unbolt heater core.

Answer 2

If it is leaking coolant it needs changed. If not leaking don't change. Go get a CHILTONS or HAYNES repair manual if you need to change it. Lot of heater cores changed for wrong reasons.
