97oldscutlas Posted May 3, 2012 Report Share Posted May 3, 2012 Hi all! I'm look for guidance if i can simply replace my current radiator with the largest size as all the sites say each size will work for my '97 olds cutlas. I've read on some post that going larger would require a different driver side fan, but each that i read wasn't a 3.1... Does anyone know if this is the case? If so, do you order the fan based on the radiator size? Thank you! Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted May 5, 2012 Report Share Posted May 5, 2012 You can use a 1 /38" thick radiator from: CUTLASS 94-95 6-207 (3.4L) GRAND PRIX 94-95 6-207 (3.4L) LUMINA CAR 94-95 1-3/8" thick MONTE CARLO 95 1-3/8" thick Without any mods.
