I have been looking on Rock Auto for a new heater core and noticed that the AC Delco core and the Spectra Premium core pictures show the pipes in different positions. The part #'s match, but they look different and there is a $47.00 difference. The Spectra has a note about "variable pipe positioning......". Does this mean that the pipes will swivel to the position as shown on the ACD core? The ACD positions appear to be correct for my core, which is still installed. The same Spectra core shows up on Amazon, and they state it is a correct fit, but the tubes look like they are in the wrong position.

So does anyone out there have any experience with this situation, cuz I could use the extra $47 for next Blazer repair?

 

I just installed the TYC heater core from RA. It is even a few bucks cheaper. The pipes on that one did swivel to help align them properly. It said this in the installation sheet enclosed in the box. The Spectra is probably similar.

 

Thanks for the feedback. I feel better about ordering it now.
Did you remove the whole dash or just pull it back & down. How did it go??

 

I pulled the dash. I was replacing the entire dash ***'y at the same time. I have read others have done this by just tilting the dash down, but I can't, for the life of me, figure out how. I dropped the steering column which was pretty easy. I also removed inner fender to access the lower bolts from the engine comp't side too. I didn't want to cut the HVAC housing tabs like so many write-ups recommend. It was quite the job really, but would be so much easier now that I have done it once. I hope I don't have to.
