The Heat exchange occurs in the radiator and the ability of the radiator to dissipate the energy of the water flowing through it. To prove my point, go out and get in a traffic jam, watch as the heat builds in the coolant system and then when it is good and hot, rev your motor and see if the added coolant flow cools the system........it won't The only thing that will change the temperature is airflow over the radiator....not coolant passing through the inside. The slightest forward movement will bring the temps down almost 10°. If this were true, why do we have a water pump? Airflow through the radiator is very important. Airflow plus coolant flow equals good cooling. Our aurguement was just about coolant flow. We all know when things get hot the ECM turns on the fans and things cool down. Reving your engine only changes the flow unless you have an electric pump. On other older cars, reving the engine also increased the fan speed. You can turn the fans on by using the A/C or modify your fans so you can turn them on manually. I've been in stop and go traffic in 100 plus temps and with my fans on (manually) and my electric pump running, I've never gone over 210 degrees. I just have to remember to get out of the manual mode or I'll get a "Check engine soon" when I go over 35mph. I've been using distilled water and the green stuff since I installed the electric pump. |
