Heater Core Swap 1961 Apache

[par4tom]

After 7 months, several hundred hours and many false starts, I finally got the L48 350 running. New MSD ignition, Street Avenger Carb from Holley and new intake manifold. Pretty much everything on this engine is new...

So...I fire it up, seal all the leaks for fuel lines, water lines etc...and I think I'm home free.

Then I look down at my feet, there is this stream of coolant running across the garage floor out down the drive.

So, I shut everything down and look inside the cab to see a fresh rush of coolant raining out of the heater core.

Now, I'm not surprised too much (it was the original heater core and hadn't been used in 20 years) and honestly the rust that had been falling out gave me room for pause anyway.

Can anyone here give me a link to swapping out the standard heater core in a 61 Chevy. It looks like a few bolts around the box, maybe a couple of larger bolts holding it in place...any secrets to switching this out? (I ordered a new one from LMC for $69 and it should be here by Friday...Fresno CA time!

Thank you...

If your heater core is under the glovebox, like the one in my '63, then you are pretty much on it with your description of how to remove it.

Here is mine I removed from my 1962. Hold on to your core. I had to use the old side tanks on the new one because of pipe routing.

LV,
Thanks for the help. You were spot on with those photos. Took me less than 10 minutes to unbolt and pull out. Pretty simple with your input...
Best,
Tom
