Water pumps

[RogueJeepr]

Are any of you running a flowcooler hi flow water pump ?
Whats your experience with them.
I've read 1,000 different threads on the whole XJ cooling system , pumps, fan clutches, ect.

I'd like to know as well. People seem to love or hate them. I've heard better things about the hesco pump

No complaints performance wise with mine, however my cooling system was designed and built right from the start. I don't have comparison data to offer.

My complaint is their false advertising or deception I should say. The pump is not theirs nor made, manufactured, casted, yada, yada, yada......in America. The pumps are casted in Korea or Thailand for GMB Corp, the same chit you'd buy at Oreillys. Depends on currency strength month to month I'm sure. Flowcooler simply exchanges the OE impeller with their fancy colored billet wheel.

The issue I have is the deception and sketchy bearings and seals.

In short you're buying an overpriced gypo cheese dick generic foreign pump with some bling slapped on by a deceptive California business.

RogueJeeper What are you trying to accomplish/cure? Perhaps we can help.

I installed one with the stroker last year.

No complaints yet. I don't know that helped. I have a manual transmission, so no transmission fluid to cool, but I do have a engine oil cooler that puts a little extra demand on the cooling system. I Still have the factory two fans. It seems I have to run the Napa HD fan clutch in the summer too keep temps bellow 210 while crawling. (but I have other issues that have been discussed elsewhere)

Im just going through my whole cooling system and ordering parts these next few days.
The only time I have overheated is going up very steep grades towing my teardrop on hot days. Once the heater gets turned on it returns to normal.
I'll be getting new.
Radiator-----------O.E. 1 core Napa
Pump--------------- undecided
Thermostat------195 hi flow, unless I find a 190.
GC clutch fan-----Napa

Already have some hood spacers. I can return to stock in the winter.

Is your jeep auto?I have the pump you mention And I like it. Mine leaked for a little bit the first little while but stopped. Guess that's normal. I never got hot running at EJS this year. I see you are also getting a new radiator. Is something g wrong with the one you have?

 

[Omgbecki]

Oh. I'm guessing you have a XJ. Never mine the radiator question. I was wondering if you might be interested in a used aluminum 2 core out of my TJ because I'm looking for a next to nothing stock one but as far as I know that won't work for you. I'd still get the pump if I had to do it again.

Go with a 2 or 3 core radiator and you will be better off... the single core will not cool as much as a dual core.

 

[RogueJeepr]

While looking at GC fan clutches. I found the HD clutch and also found this severe duty clutch.

Severe duty.

I've read alot about that debate. It's seems some of those had switched back to the O.E. single core.

I am willing to bet it is for heating purposes. I love my set up. Never hits 210 unless I have the AC on blast and in the city. But in my situation I want to run a electric fan and my rad is too thick.

 

[Tonkaman]

When I was having issues with my bike over heating the only thing that finally made a huge difference was switching coolant to Evans. That stuff is expensive but so so effective!

I know it's not what you asked but think about it.

In the TJ world, I have yet to see any radiator work better for the factory 4.0 than the factory plastic tank radiator. Pirate and other forums are littered with threads of guys switching to aluminum multi cores and not getting anything out of it or actually losing cooling ability.

My factory radiator has been weeping a little bit for a long time, like, for about 80,000 miles. I just top it up once in awhile. When it's time to do the water pump I'll do the rad too. But I'm going to use factory parts for both.

Mine's been dripping every now and then. Today I saw a few drops a minute.

Just came back from Napa.
With parts !!!

Now I just need a thermostat.

I kinda wondered about the 2 core option. It was for a right hand drive but the only visual difference I could see was the trans line's are on the passenger side. Seems like there's room. Oh and it's a 1/2" taller.
Looking back, I'll always wonder.

The Napa 272310 (only from Napa) is what everyone said was the one to use. I haven't heard anything on the 272314. I have the 310 and it moves more air than the OEM.

As for radiator I know that everyone has tried everything with them and it seems hard to beat the OEM style radiator, I seem to remember that single core with a high flow pump and tstat was supposed to be better, but I can't recall for sure. Stick with the 195 tstat, the EEC is programmed to run with that, if the engine doesn't get up to temperature the fuel mix will not be correct, and motor won't run as efficient as it could. (If anyone wants to argue with me about that start a new thread, with EFI you can't just "pull the tstat for more power")

I am surprised that I don't have one of the fancy 3 electric fan setups yet... http://www.4wheelparts.com/eSearch.aspx?Ntk=primary&Ntt=flex-a-lite

Already have some hood spacers. I can return to stock in the winter.

The internet says that will cause the hood to NOT crumple in a wreck. I don't think that the plastic cowl would be enough to make it crumple, and with the hood spaced up the bolts just snapping and the hood decapitating the driver.

Did you come across any of this. It seems every time someone spaces their hood someone who claims to be an EMT has seen a hood go through a windshield because it was spaced up.

Nathan

 

[RogueJeepr]

Yeah , those darn EMT's.[emoji1]

When I asked about the 314 , they said was unavailable. Maybe just wasn't in stock, not sure.
I was hoping to compare the 2.

Well. I just ordered the flow cooler water pump.
I'll give it a try. I have the Napa pump as a spare just in case.
Also gonna clean out my a/c condenser before the new stuff goes back in.

(sorry for the mild thread hi-jack...)

Yesterday I made a joke about not having a three electric fan setup in my xj. Mainly because the flex-a-lite setup is $1000.

Anyway I came across Dirtbound Offroad setup for $500 (out of stock)
http://www.dirtboundoffroad.com/electric-fan-conversion-kit.html

But they sell the shroud and you can assemble your own kit for about $500. The thing that really got me excited is this fan controller they have;

http://www.dirtboundoffroad.com/electronic-fan-controller-70-amp.html

the specific thing that got me really excited about the fan controller is that you can have it run when you shut off the motor for a set time, which would help with my "heat soak" thing.

So at some point I'll probably be doing this.

My only real hesitation is that I have seen a few used ones for sale on 4x4 forums, if they are so great why are people selling them right?

After doing that research Google popped this radiator into my news feed...
https://www.mishimoto.com/engineering/2017/07/jeep-xj-cherokee-radiator-part-1/

On sale for $320!

I have so many hoses and wires running around the sides of my radiator it may not work for me.
