If you have the 2001-2006 GMC Chevy Big Blocks that haul you might be finding it runs a little hotter under a load.  We designed an impeller with an increased vane count and a reduced impeller vane clearance to take care of the problem.  It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids. 

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot Topkick or Kodiak engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

From 0-3,300 RPM…Nothing Beats a FlowKooler!

Exact item ordered, quick delivery
Size: 9.5, Color: Black Polished Full Grain
I ordered these black Cole Haan penny loafers for casual wear with jeans, khakies, and even business casual with slacks and a jacket. They've always worked perfectly for these uses. The Cole Haan version is the most versatile and still meets my sophisticated look criteria. I wear a 9 1/2 M with almost all other shoes. I have found Cole Haan to run slightly wider and slightly shorter. This fit will work with thin and no socks and a little loose in width. . I'd likely order a 10 N next time. I tend to forget this but it runs consistent with me for Cole Haan. 5 stars for the shoe and service. My bad on the slightly off fit.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

Really nice shoes
Size: 9, Color: Black Polished Full Grain
My husband enjoys wearing these shoes. Very classy looking. They fit well. They arrived quickly. He liked them so much he ordered another pair in a different color which have worked out just as well.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr
