Last night I finished all the center console gauge and accessory wiring, so that meant today was test drive day.
I did one short trip to the gas station and back...maybe 6 miles total. The AFR numbers all looked good, and I saw about 3-4 psi of boost. Coolant temps were 194-196 and creeped up to 199 at a red light with the AC on....that all went fairly well.
About an hour later I went out for a bit of a longer harder test drive and ran into some cooling issues.
Near my house I have a 10% grade road that runs up the mountain for about 4-5 miles. Pushing up the hill at about 50mph I only saw maybe 4.2psi, but was more concerned with the temp spiking up to 212 degrees. On the way back down I just coasted in gear and the temp came back down to 190 pretty quickly. I then drove around town on the flat (30-40mph), a few traffic lights etc. While moving at about 40 my temps were in the 196-200 range, when I stopped at red lights it crept up to 208-210....hot enough to make me worry. Ambient temp in Draper, UT today was 90.
I have a new Ron Davis radiator, all new cooling system components including a new blue hub clutch modified by landtank, it’s possible this one didn’t get modified properly, or the 15k CST isn’t cutting it for the hot UT temps.
I also have a York setup and dual batteries...so not much room under the hood for hot air to escape.
I also have only put about 15 miles on the motor since the batteries were disconnected, so the ECU is still relearning.
I am considering a few options:
1) Cutting vents into the hood
2) Modifying the blue fan clutch with 30k CST
3) Installing a pusher fan in front of the condenser
Would be good to hear if anyone else has had similar issues.
