HD cooling system

[tpd310228]

when i bought my jeep i was told it has a heavy duty cooling system or something in it. i have no idea what it looks like but my friend said it had to do with the fan thats installed on it... here's the pics of mine (just got back from the lake still gotta get all the mud out)

You do not have HD cooling,you have the shroud/electric fan parts but are missing the secondary mechanical fan attached to the waterpump.

does not having it make much of a difference compared to having one?

Less towing ability,only 3500lbs compared to 5000lbs.No back up cooling fan when the main electric fan stops working from being packed full of mud(noticed dirty engine bay).

[tpd310228]

does anybody have a part number or the name of the fan or something?

 

[tpd310228]

That is just the clutch part,you'd need the actual plastic to mount to it also.

Keep an eye out in junkyards, I have scored the mechanical fan and shroud. WJ's used the same p/n electric fan as the HD cooling KJ's.

Having the HD cooling also makes a big difference when off roading.
Well worth having.

I'll save you the work. Here's the nylon viscous fan from MoparPartsAmerica.com


And here's a thread showing the install & parts needed (though you already have the shroud - the hardest part to find!)

The Hayden viscous clutch can be found at SummitRacing.com or nearly any other parts store - including O'Reilly's, etc.

This one time I'm going to have to disagree with you Ry,well just about the mechanical fan part of the HD cooling.

When I MOAB earlier this year my KJ without the mechanical fan was running cooler then USAFCOP's KJ with the mechanical fan.He had a new fan clutch and radiator also as they were replaced during his SFA swap.I was running 10-15 degrees cooler and both of us have the updated cooling fan relay.

I only added a huge AUX trans cooler,in addition to the in-radiator trans cooler, and functional hood vents.

Early this month when I was wheeling it was in the low 60s (so not that warm outside) and at one point when I stopped to grab a drink (and get rid of a previous beverage :cheers: ) I leaned on my hood. Damn thing was HOT - though the gauges were all reading normal. Fans were doing their job moving the hot air through the rad.

My first thought went to the pic of your Gila monster driving into a creek and the hood vents showing nicely. Think I might invest in a set of those Run Cool vents.

They work and they do look good at the same time.

I'm thinking of doing my original idea.

Or use the vents I have and the ones I just made.
