Heater core *sigh*

Just noticed the dreaded coolant dripping on my passenger seat carpet. Not a good sign with winter coming soon. I'm trying to decide if I take the whole damn dash apart or just pay someone to do it. The benefit of pulling it apart myself is that I could respray my dash like I have been wanting to do.

Mine wasn't too bad, but I didn't pull the dash out completely. Heater cores suck.

Re: Heater core *sigh*

If your car didn't come with A/C it is a fairly easy procedure.
If it did then removal of most of the dash is going to be necessary.

When you replace it buy the best one you can get, because you sure won't want to do it again.

I didn't drain mine, figured I'm not replacing it so there is no need to drain.

It's generally good practice to change the ac evaporator coil along with the heater core. That way you don't have to do the process over again if the old ac coil goes out.

The heater core placement must have been one of the biggest design flaws in these cars...unless Ford thought they would last forever.
