In the morning you start your car, the thermostat has been removed as per recommendations with fitting a EWP and not having a standard water pump, and therefore there is nothing to stop the flow of coolant through the motor.Instead of the water flowing at a speed related to the engine revs thoughthe EWP is allowing only a small flow of coolant through. Your car is now up to operating temperature, the thermostat slowly opens, and coolant begins to flow. Your car gets up to operating temperature and the EWP continues to monitor what flow of coolant is required to keep the engine at that temperature.You hit a traffic jam or a heap of traffic lights, your car continues to idle but there is little air flowing through the radiator to cool the coolant, your temperature starts to rise. The coolant is flowing as slow as possible also due to the lower engine revs. You hit a traffic jam or a heap of traffic lights, your car continues to idle but there is little air flowing through the radiator to cool the coolant, but the EWP continues to monitor the engines temperature and adjusts the flow of the coolant to suit. The EWP is adjusting the flow so that it is going slower than the standard water pump could flow or higher than it could flow at extreme revs or anywhere in between as is needed. At this stage if you also used DC Thermatic Fans you would also have a flow of air through the radiator equivalent or better than driving on a highway at speed, even though you are stopped You finally get home with your overheated motor and shut it off, there is now no flow and the coolant rapidly fails to do anything as it sits still in the motor and begins to heat up, now rather than cooling your motor it is maintaining the heat that is in it. You get home with your motor that is still sitting at ideal operating temperature and switch it off. Now if you use an item like a turbo timer you can have the EWP to continue to operate and cool the motor, avoiding any heat soak, after a few minutes (however many you have it set to) the EWP shuts off and your motor is left in a much better condition, not only did it not overheat, it was also allowed to cool past the point where the other motor could have.You go for a long drive and notice the car overheats easily even at speed on the highway, most likely your thermostat has failed and no coolant is flowing, time to pull over and pull it out and replace it (if you have a spare in the car and a gasket) or go into a mechanics and hope they can fix it without bankrupting you. Your thermostat has failed, luckily it's sitting on a shelf at home since and you no longer need it, the EWP alters the flow as needed, you no longer have to trust such an unreliable mechanical device as a thermostat to adjust the flow. You take the thermostat out so that the car stays as cool as possible. Themotor now has no restrictions to coolant flow which isn't as good as it sounds. It means slower warming up, and a coolant flow that is solely based on engine revs, even when cold. A cold motor is also less fuel efficient.You take the thermostat out (as required when using the EWP alone).The coolant flows very slowly when warming up, much like if the thermostat was still there, but is not dependant upon engine revs but rather the conditions the engine is going through.
