what is the difference of having a hi-cap cooling and not having one?

Welcome to JustAnswer, my name is XXXXX XXXXX X'm here to help get your problem resolved. Not much of a difference other then on this sytem the overflow/coolant tank/reservoir is pressurized. On other vehicles the radiator is pressurized and if overheats the pressure is released through radiator cap into overflow tank. On this vehicle the tank has a pressure valve so if it overheats coolant is released onto ground. Only real difference is on your system the cap must be tight. Let me know if you have any questions and only rate once satisfied. Thanks.
