Last trip up to Big Bear the X ran hot the whole time and it was hard to keep it cool. Upgrades were a must!!! Today I installed a the supercharger radiator (2 row), 170 thermostat, and wired the second E-Fan to also run off of a switch instead of the thermostat controlled. Also a plus for water crossings to not have the fan spraying water everywhere. The second fan would come on rarely and wouldn't stay on when running hot. I also bypassed the transmission line from the radiator to the external cooler only to hopefully keep the coolant temps down. Only issue I had was when I sealed the thermostat housing with RTV it leaked. I used a gasket the second time around and no leaks. Hood vents looked too pricey right now so for the time being I raised up the rear of the hood 1 inch. With the fans running ALOT of hot air escapes from the opening vs getting stuck under the hood.
