Heater box - paint the inside?
Got some time on my hands so thought I'd take my OEM heater box apart and rebuild it. It came apart pretty simply and looks like a no-brainer reassembly. On the diaphragm's that direct the air flow is a foam gasket/seal. It's badly deteriorated and needs to be replaced. For all you guys that have already done this, what did you replace it with? Thanks!

Re: Heater diaphragm gasket/foam - what to use?
Purchased a kit from LMC Truck. Check heater components/cooling section in their catalog. Part #43-1054.

Re: Heater box - paint the inside?
Now that I have my heater disassembled and my new gaskets ordered (thanks Lenny!) , the inside only had mild surface rust. I've wire brushed the metal parts and the decision is whether or not to paint the inside. Thoughts anyone?

Re: Heater box - paint the inside?
On the inside that doesn't show I used rust reformer by Rust-Oleum on mine. It is sold at auto parts stores and Wally World. There r other brands of it also.sargentrs wrote:Now that I have my heater disassembled and my new gaskets ordered (thanks Lenny!) , the inside only had mild surface rust.

Re: Heater box - paint the inside?
I cleaned mine up and sprayed it with Rustoleum Self-Etching primer.
While the box was apart, I was able to trim/adjust the flappers a bit to make sure it got full fan power to the defrost ducts, seems to help a bit.

Re: Heater box - paint the inside?
Thanks guys! When ya'll put yours back together, did you rivet the back on or use screws or bolts/nuts?

Re: Heater box - paint the inside?
I used the screws I removed and where there were no screws I used rivets.

Re: Heater box - paint the inside?
Thanks lenny! I may just go back with bolts/nylon lock nuts. I may have drilled out the rivets with too big a bit.
