Hi guys, new here. I was just wondering if anyone knew, or can tell me where I can find out what tempature the fan clutch engages at on a '93 Dakota with a 318? The clutch is going out and I'm wanting to install an E-fan, but I would need to know the temp the fan should cut on at, so I can set it up properly. Thanks...

Really the choice is up to you at what it turns on at. It depends on your driving, towing, and the weather you're normally in. I would probably have it turn on at 190-195 and cut out at 180.


On my Durango mine turns on at about 195-200 and it works well even in the 100+ weather, but the 4.7 is a totally different monster.

 

Thanks man. I belive my truck has a towing package. It has both trans and oil coolers as well as a power steering cooler. The truck normaly runs cool, and the fan doesn't seem to kick on too often. Is it possiable that it's equiped with a higher capacity radiator?

I just wasn't sure if I needed the fan to kick in every time the thermostat opened, or if I needed to let the radiator do it's job for a little while?

 

Assuming you have the 180 T-stat, there's no reason for the fan to turn on right away. Let the coolant flow through the block, etc.


The only time to worry is if the temp hangs around 210-215+ for too long.

 

Alright. I'll probably set it up to cut on around 190-200ish. If the coolant on the cool side of the radiator (botom) is pushing higher than that then I'll assume the radiator isn't able to exchange the heat on it's own, and there fore would need help from the fan. If you think about it, under normal operation in cool weather, the thermostat will allow the coolant to get up to the rated tempature, then open. If there is enough cool airflow over the radiator, the coolant tempature should never exceed that tempature. Humph... I think 190 will be safe...
