Heavy Duty Cooling???

    I have a 1975 CJ 5 with a 258 I6. How do I know if it has H.D. cooling or not??? I'm looking to put in a fan shroud and they give the option. It hasn't had one since I bought it, but I think it could use one.
    Thanks

    I'm not certain. but it may mean the difference between a 2 and 3-row radiator. It could also mean a fan shroud or a different fan. Even if your Jeep didn't have heavy duty cooling, the shroud will still fit.

    jpflat2a what's that noise?

    yep, what Tim said
    typical HD cooling back then from factory was maybe a larger 3 row, higher number of blades on the fan (5 vs 7), shroud, and a fan clutch
