Does anybody have any experience, good or bad, regarding Flow Kooler water pumps?

I'm thinking of installing one of these when I replace the radiator this spring. I'm going with a DeWitt's aluminum direct fit radiator.

Any opinions on Flow Kooler?

 

First I heard of Flow Kooler, I see that summit carries them. If it were me and I was going to the expense of installing the Dewitts Aluminum Direct Fit radiator, I would use the best aluminum pump:

I am using the Moroso aluminum pump, bought it before I knew about the Stewarts.

 

Thanks, B71. I checked out the Stewart website. Would you recommend using the Stage 1 or Stage 2 version?

 

I used one in my 1996 Jeep with 5.2 engine and it made a big difference.There was a large temp decrease in just changing the waterpump

 

I put a Flow Kooler on my SB and it has worked fine. Only one problem, it was a short pump, but I never measured it. Seems it may not have been a Corvette specific pump as I ordered because I had all kinds of belt alignment issues putting everything back together. Besides that, it has been great!

 

I have a Flow Kooler pump in my '72 for years and it is great. Temp stays low and the pump is reliable. I would recommend it.

 

I did something similar to what you are doing. I installed a Dewitt Direct Fit aluminum radiator and a Stewart HP aluminum pump and T-Stat and filled it with Evans NPG+ coolant. I haven't got the engine above 186F since I did it. That was 4 years ago

 

FloKooler pump dropped the temp on a friend's Trans Am by 25 degrees. No other changes.

 

b71 hit the nail on the head - either Stage 1 or Stage 2 Stewart. They're very well built and last - I had one on an engine for 180K before it finally gave up the ghost. This was on a serpentine belt system, so it had plenty of side load from the belt.

 

I can't say what I think of this vendor on the forum That is putting it nicely.

All they are doing is refurbishing old pumps and installing a wider impeller to get higher flow. It's a good sound idea, that is if you get a pump from them that doesn't have a problem.

I used to have a custom blue metal flake motor. I buy a new FKooler cast pump and I polished it up because of the ruff casting flashing and paint it blue to match my motor. I reinstall the pump and fire up the motor. The thing is dripping anti-freeze out the snout because the seal is bad when they rebuilt it. I had to have my Vette running - right now! So I called them up and they gave me the run around about without a return they coudn't send me another pump. Mistake #2 on my part, I agreed to buy another pump and they agreed to credit my card when they got the bad one back.

So there I am polishing and grinding the second pump. With paint and reinstalled. 2-3 weeks go by and my Visa bill arrives with two pumps and shipping cost. So I call flow kooler and they lady tells me that since I painted the pump they could not refund my money. So I got pissed and they did not refund my money, but they did send another one. So I have a brand new one sitting in a box and my Blue one still on my old 355 ci on a motor stand in a plastic bag.

 

Customer Service in America, ain't it just great?
