1681CI 1963-1977 Small Block Ford cast iron 5-9/16" water pumpSmall block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller, an increased vane count and a reduced casting to impeller vane clearance. 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

Small block Ford running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller, an increased vane count and a reduced casting-to-impeller vane clearance.  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 Ford 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!

Color: Upgrade-apricot, Size: 15.6 Inch, Color: Upgrade-apricot, Size: 15.6 Inch
Perfect for work! I use it for laptop, charger and few items necessary at work. I have a few blocks to walk from parking to work location and this bag has replaced last backpack and purse. Much easier to carry one item than two or more. Plus, it has enough room if you need to use it for clothes and toiletries (road-trip) or carry-on.

Size up
While I like the concept, it’s not true to size. I cut the tag off thinking this fit well, as I wear 38G in most HSIA bras, I found that throughout the day this rode up and gave me “quad-breast.” It also broke the skin on my back where the anti-slip rubber was on the band. It has potential, maybe if you size up with band and cup.
