hey guys i just had to replace my heater core and auto zone oreillys and advanced auto all tried to sell me an aluminum heater core that wasnt the right one even tho the part number was right

i got lucky and called napa/auto tire and parts store and they had a copper one that fit in the factory spot

just a heads up

GOOD TO KNOW!!!!!!!!!! My heater core literally just went, thanks for the post - beyond ironic... haha

Just Curious What Was The Make And Model Number.

I might need a new core from napa...that gonna be a job.

The general one that doesn't fit is
Part number 399083

The napa part number is 6603284

Just for the record napa s part does have the bad part number on it also but it's a secondary number

The napa number fits !

Is this it

That One Is Aluminum, 88gtadan Said The One He Used Was Copper.

OP, do you know the manufacture brand on the core you got? thx

According to napa that is the number I used and on mine showed aluminum on the box but part was copper ( looked identical to mine out of car) I think the pics are just generic aluminum on all pics But YES napa part number is correct
