Review on Cold Case Radiators Performance 1967 1969 Replacement Parts in Engine Cooling & Climate Control by Cedric Ziebart

I bought a Camaro 69 396/325 that had been sitting in a lot for over 30 years and one of the things that needed a fix was the original one small cooler unit, flexible plastic fan and the lack of a case that he had. I chose the Cold Case cooler because it fits directly (in the second set of mounting holes) and still offers much better coolant flow. Since I didn't have anything suitable for a fan, I decided on a kit with an electric fan. With a long water pump, space is limited and this fan assembly barely clears the water pump pulley. So far, so good. As an initial setup, I simply hooked up a relay to keep the fan running as long as the key was on. I also added a new 160 degree thermostat to have a known temperature at which it opens. During a test drive in the city, the temperature rose to around 175 °C and then steadily increased, even at constant speeds around 35 °C. 40 km/h. It didn't stabilize until about 215 degrees. This is too much for my comfort in mild conditions. I want to be able to drive this car on the highway with its 3 speed Th400 and 3.73 reverse gears which means I need a wheel to breathe. And at speeds that should normally be cooling without a fan or cover, it runs more than 10 degrees above the thermostat temp. So the other day I took off the electric fan and fairing, ran to Heartbeatcity and got the report. large fan shroud, fan, clutch and mounting hardware. After replacing it with an OEM style mechanical fan, it now runs at around 175 degrees all the time, from idling at a standstill to continuously driving at 3krpm. It's a good heatsink, but the fan setup is more like air. Restrictor as a means of airflow. Recently
