I installed my c&r radiator and it came with a high pressure 19-21psi cap.. is that too much pressure.. i mean can i run it safely or will it damage my hoses and or motor. i thought the higher the pressure the higher the cooling efficiency.. any help would be awesome.. thanks

 

i would run what it came with the radiator you got my give different flow and pressure just keep an eye on it and if its not working correct just get a stock one.
