Making a list for everything needed for installing a new heater core
Hello everyone. The heater core on my 1998 Cherokee Classic is leaking and needs to be replaced. I am making a list for everything I should replace while I'm in there and what tools I will need. Here is what I have so far:
- Heater Core (duh)
- A/C Evaporator (plus A/C discharge)
- Blower Motor
- Weatherstripping (double-sided sticky)
Do I need any specialized tools? What else in there should I replace?

...and filtered water (don't use tap water).
Not only drain your engine's coolant, completely flush it out and replace with new. Coolant becomes acidic over time (due to the sensors) . If you're installing an aluminum core, you especially NEED to put in new coolant.
Is your current blower motor bad? If not, I would keep it.

I'm going with a copper core, but the coolant will be flushed regardless. I'll add filtered water to the list.
It's working as of right now, but since it's over 20 years old, it's bound to fail eventually.
Not old enough for beer yet... I'll go buy some soda instead lol.

Distilled water and not filtered. Got it.
Most definitely... I'll take a picture each step of the way so everything goes back together right.
