My Ford Escape runs hot in the Texas heat (102 degrees) pulling a small trailer. I want to add a heater radiator to increase the total volume of coolant and the total radiator surface. The additional radiator will also have a fan on it.
Rather than just putting it inline with the existing radiator hoses, I would like to install a 12V water pump to ensure adequate water flow.
Can someone point me to a 12V water pump that will keep the water flowing and handle the system's 21 lbs of pressure and 230 degree heat?
