dasbulliwagen Posted September 16, 2012 Share Posted September 16, 2012 I adapted one from a Jeep Grand Cherokee WJ 99-04. I used 2- 2.8 V6 fan shrouds cut and epoxied onto the fan unit to fit over the radiator. Ive noticed too, but havent tried a fan setup from a PTcruiser. It is about the right size for the 2.5-2.8 radiator. You will also need to get a fan controller that has an adjustable temperature switch to turn the fan on and off. Some controllers have a soft start built into them so that when the fan comes on, there isnt a huge amp pull on the electrical system. These controllers can cost anywhere from $40 on up depending on what you get and can be bought from any speed shop, Summit, Jegs, etc. The benefit to this is to lessen the drag on the engines rotation. It takes a few horsepower to turn the fan all the time, thus eliminating that drag will free up a little power. Link to comment Share on other sites More sharing options...
88whitemanche Posted September 17, 2012 Author Share Posted September 17, 2012 Yeah that pics looks real nice...i mean aslong as it cools because I was at the drive through on friday and I was waiting for a while and the jeep just.startef heating up I have a new thermostat new waterpump new radiator and new antifreeze and my fan clutch is in great shape...idk wouldnt understand wjy it would heat up like that....but when I'm driving the temp drops tremendously...amd just got a new sensor....have u guys heard about the ford tauris fan being in the jeep?

NotMatt Posted September 17, 2012 Share Posted September 17, 2012 Do you have a fan shroud on the factory mechanical fan? If everything is in good working order and you have a fan shroud, you really shouldn't have problems with the stock setup. I can tell you one thing for sure, the electric fans you get at the parts store (Hyaden, flex-a-lite, others)... be very careful and read the specs fully... most of them aren't designed as a mechanical fan replacement, just to be run in addition as a pusher in front of your rad. The 16" Hayden curved blade fan is only 1500 CFM, and it is NOT enough to cool down a stock 4.0 in a wrangler by itself (trust me, I tried). The smaller ones that are a better fit for the location of your stock mechanical fan are going to be under 1250 CFM. For a good idea of the limitations of this type of fan, I read somewhere that you generally need a BARE MINIMUM of 2500 CFM from an electric fan to cool a small, stock V8 (302, 305, 350, etc). If it were me, I would figure out what's wrong with your cooling system. Are you SURE your fan clutch is good? Do you have a shroud on the mechanical fan? Is your radiator and/or condensor clogged with debris? The stock setup with the mechanical fan and OEM auxillary electric fan is a very good setup that you should be able to leave idling all day and not have it overheat... so if it's doing that, something is wrong.

88whitemanche Posted September 17, 2012 Author Share Posted September 17, 2012 Ni I don't have a fan shroud at the moment...i was thinking about grabbing one from the junkyard well the inly one that has a comanche in miami but I was sooo pissed at an failed attempt of loosening yhe bench seat nut I got pissed and left...forgot to grab the coolant overflow tank and fan shroud...also I was in about a foot of water attempting this Link to comment Share on other sites More sharing options...
88whitemanche Posted September 17, 2012 Author Share Posted September 17, 2012 Does the fan shroud make that much of a difference? Link to comment Share on other sites More sharing options...
Jeep Driver Posted September 17, 2012 Share Posted September 17, 2012 Yes. Shroud is a MUST HAVE. Link to comment Share on other sites More sharing options...
88whitemanche Posted September 18, 2012 Author Share Posted September 18, 2012 Ok ill grab one this weekend from that comanche....thanks Link to comment Share on other sites More sharing options...
Jeep Driver Posted September 18, 2012 Share Posted September 18, 2012 The shrould directs or forces the pull of air through the raditator, otherwise the fan will pull air from around the fan itself thus losing the majority of it's efficiency.

It is about the right size for the 2.5-2.8 radiator. Interesting. I'll have to look into this the next time I hit up the P&Ps. I believe most of the time there's at least 1 PT cruiser, and a handful of WJ's there. Also, that is one clean engine bay! Makes me jealous every time I see it, Murph. :yes: Link to comment Share on other sites More sharing options...
88whitemanche Posted September 30, 2012 Author Share Posted September 30, 2012 So I ended up getting the fan shroud and huge difference in cooling even in bumper to bumper traffic didnt even get close to 200 degree barely getting over the 100 mark Link to comment Share on other sites More sharing options...
