i finished my pi intake swap. i filled it up with water and ran it up to temp to kind of flush out the cooling system. my gauge rose up to where it normally runs when warmed up but the radiator fan won't kick on. at what temp does the fan usually kick on? i'm not throwing any codes as of yet but the engine compartment just seems to be to warm for the fan not to kick on. the heater vents on the inside are blowing hot air. i already checked the fan fuse. anyone know why the fan wont kick on or is this normal?
