'72 Supreme U code w/auto, A/C, heavy duty cooling and internal tranny cooler...what radiator, how many rows, and is there a cross reference for a part number?

Thanks,
Dave

 

I believe you left off a critical portion of the image - The Chart Legend.

 

You got me there Norm, but the legend doesn't answer my questions 🤔

 

If I am reading the Legend Chart Usage correctly, if you have the L75 Engine and you have the Y72 Option, you have completely satisfied the first option & the ZN3025132 radiator is used - regardless of any other options to the right on the same line. If you have the L75 Engine, but you do not have the Y72 option continue reading to the right (on the same line). If you have the C60 AC option the ZR3025794 radiator is used, if you have the C61 AC option, then the OC4037015 radiator is used. If you have neither the Y72 option, nor the C60/C61 option but you do have the M40 transmission, then the CU4035247 radiator is used. If you have none of the previously stated options on the L75 engine contained on the same line (no Y72, no C60/C61, no M40) & you had the standard transmission (last column) then the CW3025246 radiator is used. At least that's how I read the chart.

 

Dave, I can't speak to the number of rows and any cross-reference part numbers, sorry.

 

Agreed sir, but how do we know if the ZN3025132 is 3 or 4 core?

 

Gotcha... hopefully someone else will chime in on this.

 

Sawzall?

 

Dave, I must play golf (tee time 8:30am). Have a look at this thread.
