If you own a 1983-2006 Land Rover Defender with a carburated 3.5L engine with a "viscous" fan AKA fan clutch then you have probably have heard all of the reasons they overheat. Some blame the steel liners shifting within the aluminum block.  Some blame combustion gases in the the coolant and/or the crankcase system.  Others point to micro-cracks in the block, porosity in the block and a myriad of other reasons.  One customer called us to say that he noticed the temperature rising at a low idle and he discovered our pumps as a possible solution.  Unfortunately we did not have an impeller for this pump but he has convinced us to develop a hi flow impeller to increase the coolant flow rates to help mitigate the temperatures. 

Flowkooler High Flow pump impeller are CNC machined billet aluminum designed with an increased vane count and a reduced plate-to-impeller 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. 

Slow speed rock crawling means lower fluid flow and limited air flow.  A good radiator and a hi flow pump will keep your engine temperature down whether you're crawling in the hills near Birmingham or in the desert near Moab.

FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot 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.

Arm Saver
Style: Classic + 2pk Ball, Size: 26in
I loved this product as much as my dog! It saved my arm and the ball flew further than I could ever throw it myself. The rubber balls are very durable and are holding up very well for the ball chewer.

For medium sized dogs over 25 lb
Style: Classic + 2pk Ball, Size: 26in
The product is great, but for my little dog, it won't work. The balls that come with it are too large for her. I will give this out for free if the dog park for people who have medium sized dogs. Over 25 lb

Best dog throwing toy
Style: Classic + 2pk Ball, Size: 26in
Probably one of the best purchases I have made! The balls are far superior to any tennis ball. My dog likes to chew or bite down on the balls once she catches them and tennis balls ball apart. As to the actual thrower - the extra length on this one has helped me, I had back surgery and am not able to bend over I can reach the ball without too much difficulty. So to sum it up - best dog throwing toy I have purchase!
