Aftermarket mechanical cooling fan question.

[Ry' N Jen]

I am wondering if anybody knows if there is an aftermarket mechanical cooling fan that will bolt to the viscous fan clutch?

Thanks guy's

Havn't heard of one. You having trouble with your fan Ry?

No, just adding the heavy duty engine cooling to the Heep.

a friend of mine installed one on his ranger. He got an adapter from summitracing.com that screws on to the pump. Then, allowing the bolt on of a flex fan, etc.

The OE plastic one is very light and pulls massive air.The CRD guy's are swapping out there metal ones for the gas version for better cooling.

I'll check and see if I can get a new one from a dealership...

Bought mine online from one of the mopar parts sites, $65.

You can get a Hayden heavy duty viscous fan clutch from O'Reillys for about $50.

Here's the link to the Hayden site, P/N 2736, heavy duty fan clutch for a 2004 KJ 3.7 L V6 -

Here's the webpage from OReilly's, about $56 -

Check the shaft on your water pump - should already be threaded to accept the fan clutch - just remove the plastic cover and screw it on.

When you order the OE plastic fan blade, might want to order the 4 bolts that mount it to the clutch as well - rather rare combo of length and thread size to find in a hardware or auto parts store.

I'll vouch for that - the OE plastic fan and a Hayden severe duty clutch move a TON of air when it's engaged - opening the hood on that diesel after a good run on a hot day, it's like getting a blast furnance in your face.

A friend in Charlotte, Ranger1, reported his EGT cooldown times were cut in half after doing this mod.

I'm with Ryan on this one. Which plastic fan, Troy - the standard cooling fan or the one for the HD cooling system?

I can't find the HD plastic fan on any of the online Mopar sites so I need to confirm that's the one you're talking about.

One of my planned mods is getting something close to the HD cooling system (prolly without the HD shroud) and also running the trans cooler lines into the '02 in-tank rad cooler, then back out to the standalone cooler then back to the ******.

So any help on the plastic fan would be great! :happy160:

There is only one gas KJ plastic fan,it's just part of the HD cooling package,not a HD fan.

You will need to proper shroud also or there is no point adding the mechanical fan.The new shroud also requires a new electric fan also.The electric fan is the main cooling fan on the gas KJ and must be retained.

Here's a link to the thread over in the CRD section, where we've been discussing this mod. Post #21 by Lancer, top of page 3, has the latest P/N for the plastic 11 bladed fan.

I haven't had the chance to check on the plastic fan blade yet...
Been flat on my back unable to move.
I did get the HD Hayden fan clutch BTW.
Fortunate for us our KJ has the HD cooling fan shroud fitted so it's just a matter of fitting the fan clutch and fan and we'll have plenty of cooling finally!

Thanks all

When I'm not a 100% gimped I work on my classic Mini...
Talk about a tight squeeze when it comes to getting your hands in one of those engine compartments!
