Heater core replacement

[rix66]

Hey guys! I need to replace the heater core in my 66 Belvedere. Can it be done without removing the dash? I'm old and fat (ugly too) and I can't get into the tight spots like I used to. Did this on a 64 Dart, and tore up the cowl intake hoses Thanks for the help !

Take the ft seat out. Remove pass side door sill plate and kick panel makes it A LOT easier.
Does not require dash removal

When you get your new core check the in an out pipes length. I bought one put it in and the pipes were only a 1/2" out of firewall. Remove it and had the radiator shop where I bought it switch pipes.

I had a local radiator shop fix mine.
Keep the original if possible.

I bought a heater core from RockAuto that didn't really fit inside the box to start with. At least it was cheap.

It was this one More Information for FOUR SEASONS 90500

FWIW the factory unit that came out would drop straight in without even a rub.

It seems most radiators/cores are aluminum now.

I have an 88 S10 I bought a new heater core for it, aluminum, didn't fit very well, not impressed.
Learned my lesson.

Same truck, new radiator is plastic/aluminum combo.
Took original copper/brass radiator to same place.
It will out last the truck.

62 Valiant, heater core failed, took it to same place.
They fixed it without recoring it, $40 cash.
