Default Step by Step Heater Core Replacement on a 73

Hello gang, It's been getting cold out there and even in So Cal, it's gettin a bit chilly!! To the point that my wife doesn't want to ride in my 73 without the heater working. So here we go. I just replaced my leaking heater with a new one and I took a lot of pictures and wrote up a step by step showing just what I did. Now I used to be a mechanic in several auto shops in the younger years but now I only like to tinker with my own cars so I am pretty good around the shop. The total time it took me to R&R the heater core was almost 3.5 hours. Here is what was done.













































































It's all done now except for the 2 heater hoses that should be here on Thursday. I do hope this will give some insight for other readers that want to tackle this job.

Excellent write up. I will print this off in case I need to replace my '73 heater core. What heater core did you buy?

I ordered one from Corvette Central. My ride has A/C so it made the R&R a little bit harder.

Hey, Thanks guys for the nice words. I hate changing a radiator cap on a Toyota Prius but I love to do this kind of work on my 73.

I think it took me more time to write the post then to change the heater core.

Default Much thanks!

Much Thanks for documenting this!

(I recognize all of the parts from having done this job. Much thanks too for the tip on getting the a/c control out by rotating the bracket clockwise. I had a lot of trouble getting that a/c control out.)

Oddly, my name is Scott and I also own a '73 and live in California. Small World!

You should do it. It looks like a lot of work but it does go pretty smoothly.
