If your seeing hi temps and you're at slow speed or under a load then you may need more coolant flow and balanced circulation. Flowkooler designed a high flow water pump 1677 HP for these conditions.

This water pump has dual ports for the Hummer's with a 6.5L diesel that run a little warmer. If your seeing hi temps and you're at slow speed or under a load then you may need more coolant flow and balanced circulation. 

Flowkooler designed a high flow water pump 1677-HP for these conditions.  It has a CNC machined billet impeller with increased vane count and a reduced casting-to-impeller vane clearance.  It achieves greater flow rates, higher head pressure and a more balanced and 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 diesel 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.
