Thanks to all of you who helped me out with this project. Yesterday I spent the day installing the fender mounted Carrera style oil cooler. (In between, our normal 4th of July activities.)
This morning I ran the engine in my garage for 45 minutes to see if there were any leaks and of course to see if the set up even works. The metal pipes leading to the oil cooler were cool to the touch until about 190 degrees as indicated at the dash gauge (obviously the external thermostat opened). I let the engine run until the metal pipes were scalding hot to the touch, the dash gauge indicated 200 degrees. I turned on the Spal fan mounted on the radiator and waited to see the temperatures. After a little while the system stabilized at about 195 degrees. The temperature in the garage was over 90 degrees as indicated by my vehicles outside temperature gauge.
I shut the Spal off to see what would happen and within 2 minutes the temperature rose to 210 degrees. I turned the fan back on and after 10 minutes the oil cooled to 200 degrees.
All in all I’m pleased with this bench test. 1 hour after shutting the system down I inspected all the potential avenues for leaks, and there were none.
I have wired the oil cooler with a temperature gauge. I like the idea of having a redundant system to monitor the temperature of the oil (as long as the thermostat is open). If the dash gauge shows reliable as compared to the sensor put in the oil cooler I may still swap out the sensor and put in a Nason sensor for the fan.
Thanks again for everyone’s help.
