Holiday 88 P-30 Heater INFO HELP !!!!

Noticed yesterday I am dripping antifreeze from my heating coil box on the front passenger side. I would quess that the coil froze at some point and a crack in the internal coil is dripping fluid. Can't take a chance of a rupture on the road have to repair it. Do not want to put sealant in radiator.

Anyone know the source/brand/model # of the non-Chevy heater box installed on these units by HR in 88 ?

Of course if anyone else has replaced or repaired on of these units, i would appreciate any info you can provide. Thanks in Advance!

Check Mill Supply Mill Supply | Home They have a lot of step van parts (The P-30 chassis is basically just a stretched step van). I bought a heater core from these people, and cut into the plastic surround housing with an electric soldering iron blade. Once the heater core was installed, I just closed up the seam with RTV.

Once you get the core out, you can take it to a radiator shop. It can be recored. If you need to drive the MH you can join the two heater hoses together with the appropriate connector. No heat of course.
