heater cores.
they should be placed in the designer's butt.
Why not make them easy to get to via the front panel?
Ever want to be an automotive designer?
First challenge is to make everything harder to get at.
It's the dealer, he needs to make money after he sells you the car.
I've found out quite as while ago, if you use the heater, just once in a while, it will flush out ther dead water and not rust.
Caddy, use to have a system that always had the heater core, running. Even with the A/C on. To remove moistier ftrom the cooled A/C air.
Never had my caddy heater core leak.
