93CutlassSupreme Posted September 19, 2013 Report Share Posted September 19, 2013 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.

l67ss Posted September 19, 2013 Report Share Posted September 19, 2013 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 Quote Link to comment Share on other sites More sharing options...

White93z34 Posted September 19, 2013 Report Share Posted September 19, 2013 Hollander isn't always right. Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted September 19, 2013 Report Share Posted September 19, 2013 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 Posted September 19, 2013 Author Report Share Posted September 19, 2013 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 Posted September 19, 2013 Report Share Posted September 19, 2013 There ya go...If it fits, use it! Quote Link to comment Share on other sites More sharing options...
Crazy K Posted September 19, 2013 Report Share Posted September 19, 2013 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.... Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted September 21, 2013 Report Share Posted September 21, 2013 If you ever do need a radiator from O'reilly, ask them to price match 1-800-radiator. That's their supplier. Quote Link to comment Share on other sites More sharing options...
Imp558 Posted September 30, 2013 Report Share Posted September 30, 2013 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. Quote Link to comment Share on other sites More sharing options...
