Engine/Transmission (1998.5 - 2002) fuel cooler switch

[KKunz]

Does any one know where to get a thermostat type switch that kicks on at 120 degrees and off at like 80? I’m building a fuel cooler with a fan and I want to have the fan kick on when the fuel gets to hot but I don’t want the fan to run all the time

What size and type(brand) of cooler are you planing to use and where do you plan to mount cooler as not to get damaged? What about a 80* or 90* snapdisk to turn fan on/off ? I was planing to mount one close to the relocated LP. JoeZ

I’m looking at a dual circuit cooler from summit with fan I was hoping to mount it in front of the radiator but I’m not sure it I will have enough room. I have a winch bumper that I built It has 2 6 inch light mounts in it so I should have room in the bumper if needed. 80*-90* would work great

Grainger has some called Snap-Disc Controls. Some of the thermostats are adjustable and some not. I guess you could Gooogle Snap-Disc and see what pops up. The dual circuit cooler what are you using the second circuit for? JoeZ

A little off subject but,



I've played around a lot with fuel coolers and suggest that coolers going into the VP44 are not as effective as fuel coolers comming out of the VP44 (probably because the fuel is hotter and therefore the cooler more effective). The DC concept that the tank is a heat sink is totally BS.



I also mounted a H7B in the drivers side rear wheel well pocket with a fan and see that there is not enough free air even with a 1k cfm fan. The coolers need to be out in free flowing air and a lot of it. I have tried to water mist the coolers and find that concept is marginal.



Good luck

Snap Disc

I got some snap discs from this guy for my biodiesel processor, he only has them down to 120º F but they are priced right.

dual circuit cooler is for hot fuel into the vp44 and hotter fuel going out of the vp44. I hope the hotter fuel will not be to close to the fuel going in a raise the in temp

I don't see why you can't tap into one of the freon lines from AC to cool the VP44, after all you would most likely be using your AC when you need the cooling effect anyway. Just my thoughts, Rick
