The Stovebolt Site Forums The Parking Lot '60-'66 Trucks heater leaking anti freeze inside cab

Besides taking off the hoses and electrical, does the glove box or anything else have to be taken off to get to the heater core on a '62 c-10.

nope not that I'm aware of.

It depends.....

What type of heater do you have?

If it is the Thrift-Air heater, you can replace the core from under the hood. I did one a few years ago in a 1966 C-10, and it only took about a half hour

What Doug said. You should be able to get it done without having to go under the truck and stand flatfooted on the shop floor. Hardest part is getting the little bitty screws lined back up to hold the blower motor back n place. Try marking their locations with a marking pen for reference.

dunno if you have the same setup or not...

Something to check before you pull out your heater ...

I removed and installed the heater in my '54 three times before I figured out that it was leaking because my heater hoses were off-size. Water leaked where they joined the pipes to the core and ran down the pipes into the heater case, then onto the floor. The ID was larger than 5/8". I could easily tell when I poked my finger into one of the hoses, then did the same to a new hose. Dunno if the hose wallowed out over time or if it was always too large.

Good point... I had a similar issue with a water hose on my truck when I first got it.
