Heater Core

[Snort]

I just replaced the heater core in my 94. I bought two different cores, the first one had a loose pipe, the second one from a different supplier seemed fine. However both of the replacement cores seemed to have at least one less row of tubes/fins than the OG one that came out. Is this just the normal course of events where the replacement parts are lower quality than the OG parts, or are there two different sizes of heater cores available, standard and HD?

Well, if you find out there is an extra special HD heater core, then sign me up! I know radiators are 1 or 2 row.

Maybe not more rows, but perhaps wider rows on the factory one I took out. The tubes were flush on one side and set away from the core frame on the other. On the replacement, the tubes were inset from the frame on both sides. Perhaps only 10-15% loss of surface area overall.

Oem parts usually are gonna be of better quality and fit then aftermarket non upgrade type parts. You just gotta do your research thru the pick of them to find one thats the closest
