I’ve installed a coolant overflow/expansion tank supposedly made for LS1 engine swaps. I’m a bit confused on the radiator caps and actual hose routing. I’ve followed the attached diagram below, along with another diagram showing how I routed my hoses based on the expansion tank barbs, aftermarket radiator barbs and Vintage Air system I installed. I idled the engine as a quick test with the caps off for now, and idling it’s sitting around 185 degrees with the fan popping on low speed around 190 degrees . I’m not sure if I need pressurized cap on both tanks or just 1. Are there any issues with the way the hoses are run?
