    Have any of you tried a severe duty fan clutch? I'm trying to find one for my 1979 Camaro 350 V8. So far I'm only finding the standard and heavy duty fan clutchs.

    HD will be pretty noisy so I’m thinking severe will be twice as loud. You don’t really need a HD or severe unless your in the desert.

    It gets very hot where I'm at. The engine is struggling to stay cool with the ac on. I have a heavy duty clutch on it already. I recently put a severe duty on my 79 Trans Am so want to do the same to the camaro.

    Been 84F here lately and I have a Harrison 4 core rad, stock clutch fan with a 180* stat and it doesn’t go much above 180* in my 70 Z28.

    But.... Yours doesn’t have an A/C condenser dumping heat in front of the radiator and that’s when the O/P is having heat issues.

    The heavy duty clutch should help.

    Mine runs a bit warm (with A/C on) if I get stuck in stop and go traffic.
    But my A/C isn’t working now. :(

    That's both good and bad. Good for the engine, bad for the driver.

    If you are having the same weather we are having, A/C would be nice. It has been in the upper 90s here most days for a week or so now, and when we get some thunderstorms with that, the humidity gets really stupid.

    Had an 85 Corvette some years ago and it had an extra electric pusher fan in front of the condenser/radiator to move some added air. Might try something like that?

    Temps in the 90s and dew points in the 70s.
    (Higher dew points actually cool the car better due to the heavy air moving through the radiator to absorb more heat.)

    I haven't driven the Camaro in this jungle heat because I'm waiting for a new radiator hose from Jegs. :(

    I switched the clutch in my monte carlo to a “normal” clutch last fall. It had a noisy HD on on there that cooled the car great but was really loud. I have since noticed with 90 degrees and AC on, the temp rises some, and the AC isnt as cold. HD one going back on for the balance of the summer tomorrow.

    It gets over 100 degrees here at times during the summer. I'm hoping the severe duty fan clutch plus a 180 degree thermostat will help cool it back down. I'm not concerned about the noise as long as it works.
