What does it do from a 60mph roll. You may have a belt slipping. Maybe the tensioner pulley

How so? I have the CM30 pump on mine. Any recommendations for new pump? Always looking for cooling upgrades. The CM30 has not failed me yet

Search for Lingenfelter article that shows tested flow rates on different pumps. Reliability isn't a problem on most of them, problem is Johnson pump doesn't flow well under high pressure.

I just bought the mezire pump the Johnson pump lasted for more then a year which is still good if the pump is bad or not . Does having the engine bay coolant tank effects the pump?
