Heater Core...

[Workin' Rig]

Turned my heat on and get steam outta the vents, any tricks on how to get this done on a AC equipped truck?

Also, how do i know if its a high output heater or regular?

HO heaters have a larger heater core.
That's it.

There are a few articles online that describe the r&r of a heater core with a/c .

This is for a 78 but it should be pretty similar

No high output heater option for A/C trucks that I'm aware of. Don't get an aluminum core, stick with the brass.

Whats wrong with the aluminum core?

The OE rubber gasket fits like crap and from what I've heard they don't heat very well. Here is an OE style brass core, these are getting harder and harder to find as all the manufacturers are changing over to aluminum.

Ignore the "without A/C" crap, it is the right core.

If money is an issue then go with an aluminum but be aware that the OE gasket is going to need cutting and is really going to suck once it is installed. I tried one of those aluminum cores and cut my gasket and tried to make it work. I finally gave up and searched my $$$ off to find a brass core which led me to the Mustang place.

None of the big companies are making them in brass anymore, they have all went with that Spectra pile of dung.

^ Makes me want to buy a brass heater core as a back up.

I have 2 new spare brass cores now Mark.

Buy brass if you can. I've replaced the aluminum POS 4 times this year in my 90.
Lifetime warranty, but who the hell likes taking the truck apart 4 times for the same thing

You may be able to repair the brass one, depending where it went bad
