I will be replacing my mechanical fan with the electric fan from a 90-95 ford taurus fan in my 91 cherokee 4.0.
Main reason is to beter cool the engine at slow trail speeds in California's 95 degree plus weather. Last summer on some trails I would see 220+ coolent temps. Plus the possible small mpg/ power increase.
I've a read few write ups and will be as detailed as I can doing this one.
First off is I decided not to go the junkyard route I got my fan off eBay for like 78$. Man this fan is huge and pretty heavy.
Also purchased 2 60 amp relays, 210 on 195 off temp switch and a switch for the fan all off eBay.
The fan on the switch should light up green when on I need figure out how it works still tho.
This jeep is my daily driver and I will be doing all the wiring first. Plan so far is to have the fan run on low off the coolent temp switch and have high switched Manually when needed.
So I basicly will have, auto/off/ high
I wired up this fan to the battery when I got it and I'm impressed with how much air it will move.
I will also be focusing on directing cool air through the radiator.
Hope to start the wiring this week.
I also allready have a die hard AGM battery and upgraded grand cherokee 136 amp alternator.
