My radiator started leaking and with 154k on the odometer I want to replace the water pump while im in there. I was going to go OEM but Ive heard some people say if you have the extra cash get a flowkooler pump. So I have a few questions. How does it pump 2x the amount of coolant at idle and the normal amount above 3500rpm? Is it reliable? Is it worht the extra money? I dont mind spending the extra cash if its a good reliable product and will keep my motor alittle cooler when im in traffic and on side streets. Any additional input for this pump would be appreciated.

 

I dont personally have one but a lot of people do and they love em

 

Yea ive heard theyre great. Im gonna put one one when i put a a 180 degree t stat and high flow housing

 

Do not buy a flowkooler! It is the same as a stock one only they welded a metal disc to it so can act like a hesco water pump. The disc will rub on the number 1 cylinder.

 

I'll disagree with this. I run a flowcooler and have no issues at all. Only thing that happened was I run cooler.

 

I have read about the impeller seperating in some reviews. Would a stock pump and a better radiator be better for cooling the motor down? Im not having overheating issue but while I'm in there I figure improve the system some way.

 

also I was thinking of my mechanical fan. Do you think I would see a bigger difference in cooling if I did a zj fan clutch or scrapped it and put in a ford taurus electric fan. I read the taurus fan can save gas and help relieve stress on the motor but there is some extra wiring and possible alternator up grade. which is better?

 

been running a flow kooler for over a year and had no problems one thing suggested make sure all fittings and clamps are tight and get a new radiator cap thats either 19 or 21 lb. if not you will find out just how well it is sealed. i helped a buddy do the taurus cooling fan swap and he was not impressed. im running a triple 8 set up and only get warm when crawling through the rocks when its 100+ outside

 

Ok I just ordered a 2 row radiator. I'm still on the fence for a pump. Think the flowkooler pump along with a 2 row rad would be over kill for a DD? or should I just run with the 2 row with a new oem water pump?

 

You own a jeep, overkill is not a word when that happens....

 

Haha sooooooo true!

 

I drive mine everyday as well you will only notice at most a 10 degree change in temp. Biggest improvement I have is when u do get her hot it cools down much faster.

 

Agreed, Overkill is shooting sparrows with deer slugs. The term does not apply to Jeeps.

 

Are you talking about the mark on the block behind the waterpump?

I think there is a mark back there on most of our blocks. I dont think ots caused by the waterpump.

 

You saying it looks like its rubbing, but its not? I wouldn't think it would, its a mass made part... A LOT of people run them and love them...
