Is there anything else I should replace while doing the heater core?

[Moto Mike]

Greetings,
Just ordered a oem heater core for a 05 LJ (5073180AB). I will be doing the swap myself and was wondering if there should be any thing else that might need to be addressed/replaced/lubricated in there since I only want to do this one time.
Blower motor, switch and resistor seem to ok now. But we all know how that will play out: fail in minus 20 degree weather.

Thanks.

I would replace the evaporator and the foam seals between the firewall and the HVAC box as well.

AC evaporator? It's right there next to the heater core. You'd have to have the AC evacuated though, so maybe more expense than needed.

Where did you find an OEM heater core?

Don't you need to do that anyway to remove the HVAC?

Mopar Wholesale parts. 213.12 plus shipping. My HAVC is not hooked up. I decided not to reinstall at this time (after my 5.3 swap) because I feel I do not need it where I live since my top is from spring thru fall.

When I had my HVAC box apart, I cleaned it out really well and put a little white lithium grease on all the pivot points for the movable doors that direct air and any other related movable part I could find.
