1) Water Pumps built to beat the heat

 Water Pumps are designed 3nd built to combat engine overheating associated with higher performance and load applications.
 JWA Water Pumps feature a precision ground, heavy duty steel bearing that ís completely sealed and lubed for life. A specially modified high performance impeller maintains maximum volumetric flow of coolant throughout the engine.

Additional features of JWA water Pumps are:
Increase pump pressure and flow
Eliminates steam pockets trapped inside the engine block
Reduces engine temperature faster than standard water pumps
Incredibly efficient, Built to survive.
Features every performance enthusiast can appreciate. The clear choice for true high performance water pumps.
2) Cooling System Overview
Radiator
The radiator is responsible for transferal of heat from the circulating coolant to the air passing through it. Heated coolant flows into the top of the radiator from the engine. The coolant is passed through a series of tubes and fins that effectively dissipate the heat in the coolant
Radiator Cap
Modem radiator caps are actually pressure valves that are responsible for increasing and regulating pressure in the coolant system. Increasing the coolant system pressure raises the boiling point of the coolant. For every additional pound of atmospheric pressure the coolant boiling point increases 3 deg. F.
3) How to tell if a water pump is defective
1 .Check for shaft seal failure by carefully inspecting the water pump weep hole When a water pump is new. some seepage is normal in the initial hours of operation as the seal seats Other than that, any leakage that occurs is due to seal failure and the pump needs replacement. There may be tell tale trails of rust calcium and coolant deposits on the water pump housing with the weep hole as the origin.
2. Detect a worn water pump bearing by checking for side-to-side play at the shaft. There should be no perceptible play as you apply hand pressure to the shaft. Accelerated bearing wear is characterized by screeching or rumbling noses coming from the waiter pump housing. If any of these conditions exist, the bearing is worn out and the pump should be replaced
