would a NOS heater core from 68 fit a 1964 olds f85 deluxe? The only ones listed that are compatible are 98 and delta 88. just curious if it is a different heater core.

 

Hollander says they are different.

 

1964-67 A-body cars are common. 1968-72 A-body cars are common. 68 does not fit 64. B/C body car fitment is irrelevant to A-body cars.

 

Boy, I don't know about that. Below are figures from the 1964 and 1968 chassis service manuals showing the heater core for the Cutlass lines.


Here's Figure 14-35 on page 14-12 of the 1964 Olds Chassis Service Manual:





Here's Figure 1-21 on page 1-8 of the '68 CSM:




These images are identical, right down to the little "swooshie" thing at the bottom of the photo.

 

Tell em where to find the manuals these pix came from DAN!!!

 

You're right! My bad.

They're accessible at wildaboutcars.com. Free to join!

 

I wonder, though, if Olds didn't just get a little lazy and reuse older images in the later manuals because they were "good enough." Here's another Figure from the '68 manual (Figure 1-20). The right side of the core in this image doesn't look quite the same as what you would expect it to look like from Figure 1-21, which is just below and is actually the same image used in every CSM from 1964 through 1969.

 

Well - I've had both -- and probably have a 67 and a 68 laying at the shop. would have to look at them and compare. My first thought is that they are the same except for that one of them has both inlet and outlet tubes straight and the other has the lower tube curved upward for clearance behind the block??

 

That'd be my guess. In that upper photo above (Figure 1-20), while it's not especially easy to see, it does look like the lower tube is curved slightly leftward if not upward as well.

 

YES! Thats it -- heres a link to a good pic of it:

FYI, this sort of question is easily answered by looking at the RockAuto catalog. For non-A/C configurations, here's 64-67:



Here's 68-72:



The A/C configurations are similarly different.

 

Bottom line here is that YES they are different - but it appears the only difference is that the lower tube is straight on your 64 and the 68-72 has a curve in the lower tube that would not make a bit of difference in your application. the curve would be just fine or it could easily be cut and soldered -- its copper just like water pipe. All of this is concerning an NON_A/C appliation -- Air cars are different all together.


All that being said --- brand new ones are availabe for about 50 bux. and new ones arent "rotten" on the inside! I have never put an old one back in a resto project! Cant imagine the thought of new carpet soaked with anti-freeze from a leaky heater core!! ugh!!

 

Rockauto?! Gee whiz. The usual case is that the auto parts suppliers have suspect application info, not the CSM. The last place I'd expect inaccuracy would be a factory service manual. If I can't trust my Olds CSM, my universe will collapse!

 

Wow Joe --- I musta got up early this morning --- cant believe i was just a tad ahead of you with the parts catalog pic -- you did better than me thaough -- i just added the link and you took the time to copy the pic --
Anyway i think we are all on the same page - and as i said above, i would never put a 40 year old one back into a car whether if fits or not!!!

 

The last time I did my heater core I removed the straight piped core and installed the curved pipe. The reason is I could not find a straight piped one in the time frame of my repair. The 2 cores are physically the same size. The curved pipe takes a bit of effort, an extra set of hands, and the proper cuss words to install.

 

LOL!! Not if you cut about 1" off the end of it!! Oh how nicely it slips through then! and plenty of room left for the hose!! Yeah! ya'all dont need that bulge on the end either . the hose clamps work just fine. But you can also use a flaring tool and get a bit of a bulge back on it if you wish!!
