1st and 2nd Gen Radiators

[93CutlassSupreme]

Can anyone verify that 1st and 2nd gen radiators are the same, non LQ1 or anything weird like that.

 

For example, the Oreilly Auto Parts website says a 1993 Cutlass Supreme LH0 and 1997 Grand Prix L36 use the same radiator.

 

 

Thank you.

They all interchange easy enough (aside from the 3.5 intrigue) best one to get is from an lq1 car, they have roughly a 1" core depending on car and engine you mite hav swap lower hose to line up perfectly hope this helps

Hollander isn't always right.

No, but my copy seems to be more correct than most for some reason. Mine shows that the blower motor to my van is 1990-96 U van only, the junkyard tells me that Cadillac Eldorado fits and it's way different.

[93CutlassSupreme]

Thank you.

 

I understand there are some cooling capacity differences, but it looks like they physically interchange. Now I don't have to buy a radiator.

[ManicMechanic]

There ya go...If it fits, use it!

I recall being told this interchange exists, though you may have to change the fans and radiator hold downs. I have been meaning to find out if I can substitute 94+ LQ1 radiators into earlier cars....

Through my jy research should b bolt in

If you ever do need a radiator from O'reilly, ask them to price match 1-800-radiator. That's their supplier.

I have an 89 GP radiator in my 96, the fitting for the tranny cooler were wrong but the radiator seemed thicker than my leaky stock one.
