The FK water pump is a stock unit with a plate (impeler) riveted to the stock impeler. Is that plate "bolted" on worth an extra $50-60? I dont think so, a stock water pump will keep a 4.0 cool just fine.

A quality rad can be had for under $300. Looks into a CSF 2 or 3 core all metal unit.

I ran an FK water pump and aluminum radiator from www.alumrad.com for years on my 96. That setup, a new fan clutch, and an 195* OE t-stat fixed my overheating problems once and for all. That radiator is great for the price. Nice folks at the shop, too.

x2. In fact I recommend NOT getting the flowkooler pump and just using a quality stock one. Some have had issues with the plate separating from the impeller blades of the pump and thats not really something you want bouncing around in there. Spend the money on a 3 core CSF radiator from DPG Offroad. Dirk is a great guy to deal with and stands behind the products he sells. The radiator was one of the best mods I've done.

Yes the rad will fit.

Sounds like a nice setup. You should have no problems keeping her cool now.

Glad to hear that you're not getting a Flowkooler. I had one on my first XJ back in '06 and I thought it was the koolest thing in the world. Until the plate separated from the impeller and it ground to a sudden and complete stop. Luckily, I heard it and realized that the pump was no longer working as the temp gauge maxed out. I was able to pull over immediately and fix it on the side of the highway.

There it is in the foreground. Didn't take a pic of the damaged pump.

I have one and it is a GNB pump with the plate pop riveted to the impeller. If you get one and want to be sure put a few spot welds on the plate. Not really sure how much difference it makes, but Hesco makes a pump with a milled aluminum impeller and they claim it is better than the Flowmaster with no worries about the plate coming loose. Expensive though.

Flowkooler's flow improvement is mostly at low engine speeds like idle and in traffic.

I installed a Flow Cooler pump in my 2006 wrangler 4.0. The impeller is anodized aluminum with the hat milled as a solid unit so there are no rivets holding a plate on. I relaced the thermostat with high flow 180 degree model, ported the awfully restrictive thermostat housing and replaced the lower radiator hose as cheap insurance. I'v had the jeep for five years and it always ran at 210, now it runs at 190 which for me is great. I think Flow Cooler has improved their product. I would not have purchased a pop riveted impeller either but I will recommend their improved model to anyone. I paid $94 bucks for a superior product made in the Golden State, not China or even Mexico, but it would have been at least the same price for OEM at the dealership.

Other issues; I watched a dude on U-tube use a large pipe wrench with hammer and with a few dainty counter clockwise blows the clutch fan flew off. Bull! I attempted the same feat but the wrench is too big and the fan was on there pretty tight. I went and purchased a fan wrench (36mm) from autozone and had to loosen 2 of the pully bolts out so that I could use a square section breaker bar to hold fast the pully allowing fan removal. Still the video was helpful and made the job easier.

-Radiator flush first to get rid of all the crud and rust in the system.
-Do yourself a favor and change out the thermostat, its cheap and easy with all the stuff removed for the pump, same goes for the lower hose.
-After putting everything back together i filled it up with new collant only to find it was leaking at the thermo housing. After changing the gasket three times found that the orginal housing had a hair line crack, which makes me wonder if there was really anything wrong with the orginal pump. Hmmmm. So to keep it short use plain water after doing your maintenance first to check for leaks with the fan and shroud out of the way. If no leaks are present drain the very cloudy water and then refill with the collant to save some bucks.
-The orginal lower radiator hose had a steel spring for support inside the hose. The replacement did not so I used vicegrips to tighten clockwise (load) the spring to remove it and reinstall it into the new hose.
-I don't know if it was needed but I teflon taped the pump and thermostat housing mounting bolts.
-Also used teflon tape on heater tube and therm sensor on the housing.
-I used a strap wrench to hold fast the fan pully when installing the 1/2" mounting bolts.

I installed one last week. I would definitely buy one again. Appears to be one of the highest quality water pumps I ever bought. The pump it replaced had a plastic impeller...what there was left of it.
