ClassicJJ Posted May 17, 2014 Share Posted May 17, 2014 I'm out in AZ and I'm running an all stock 350 with HEI backed up by a 200 4r and soon to have 3:73 gears. I drive my monte daily but it seems to run in the 200 to 210 range when it comes to temperature and i want to cool it down alot! It has a new ac-delco water pump and someone had put a 3 cor radiator. I plan on upgrading the radiator but I was hoping someone on here who also lived in the desert could share a good experience they may of had with one. please give me all types of cooling input! thank you!

footballubet Posted May 17, 2014 Share Posted May 17, 2014 If you are running the stock radiator shroud/tunnel you could install an electric fan and it would be hidden. Does it have a clutch fan? Maybe it's not operating properly? Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted May 17, 2014 Share Posted May 17, 2014 let's start with easy things first! Â what thermostat do you have in it? 180, 195??? Quote Link to comment Share on other sites More sharing options...
ClassicJJ Posted May 17, 2014 Author Share Posted May 17, 2014 its not a clutch fan its all there though such as shroud/tunnel and i feel like its a 195 thermostat. Quote Link to comment Share on other sites More sharing options...
Mike 57 Posted May 17, 2014 Share Posted May 17, 2014 How does the fan fit in the shroud? Pictures would be good. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted May 17, 2014 Share Posted May 17, 2014 put a 180 or a 160 stat in it first and see what it does  really 200-210 isn't that bad, my 454 runs best at 190+ Quote Link to comment Share on other sites More sharing options...

Sam (Bones) Posted May 18, 2014 Share Posted May 18, 2014 that should have a clutch fan  start with a thermostat IMO Quote Link to comment Share on other sites More sharing options...
ClassicJJ Posted May 18, 2014 Author Share Posted May 18, 2014 ok if it is a clutch fan how do i go about fixing it? or telling if its not working right? Quote Link to comment Share on other sites More sharing options...
502ci Posted May 18, 2014 Share Posted May 18, 2014 I think the easiest test would be to try and spin it while the car is off and if there is resistance (as it won't make a full revolution) that is a good sign it is good. Also after the car has been driven for a while (warmed up) and you shut it off the fan should maybe spin twice and stop...if it keeps free wheeling it probably is bad.

Murphy Posted May 18, 2014 Share Posted May 18, 2014 JJ, I flushed my system real well, I disconnected the bottom rad hose to make sure I got all the crap out due the car was sitting for many yrs. I also installed a 180 thermostat, my 350 runs fine in 100 degree temps. Quote Link to comment Share on other sites More sharing options...

ClassicJJ Posted May 18, 2014 Author Share Posted May 18, 2014 Its as warm as can be now and the fan wont stop free spinning so thats a bad sign right? Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted May 18, 2014 Share Posted May 18, 2014 correct, replace the clutch Quote Link to comment Share on other sites More sharing options...
wallaby Posted May 18, 2014 Share Posted May 18, 2014 There are several options for a fan clutch. The original unit is a heavy-duty thermal clutch. There is also a standard-duty thermal, and a severe-duty thermal. There is even a "non-thermal" clutch, but it senses engine speed instead of temperature and is used only for light duty applications. Â The standard duty thermal is a simple budget-friendly unit that costs less, but allows some slippage...the engaged fan runs about 60% of shaft speed. (robs less HP from the engine, but pulls less air). Â The heavy-duty thermal is more robust and allows less slippage; The engaged fan turns at about 80% of shaft speed. (requires more engine power to rotate, but pulls much more air). The heavy-duty is recommended for large displacement vehicles with AC. Â Lastly is the severe-duty thermal which has the same operating specs as the heavy-duty, but is much larger and uses ball bearings instead of bushings internally. These are designed primarily for trucks. Â Here is some further info: Hayden clutch page Quote Link to comment Share on other sites More sharing options...
ClassicJJ Posted May 18, 2014 Author Share Posted May 18, 2014 I feel like I may go with the severe duty fan clutch. Which one would you guys recommend? Quote Link to comment Share on other sites More sharing options...
wallaby Posted May 19, 2014 Share Posted May 19, 2014 Severe is top-of-the-line. I just checked with Summit, and the severe is only $10 more then the heavy duty. Knowing that, I think I'd opt for the severe. Quote Link to comment Share on other sites More sharing options...
