Re: Overheating solved

While flow could increase with Rpm's, the pressure is constant based on the system cap. What can be reduced is the cavitation in the system. When the t-stat is closed the water has no place to flow and the pump is still trying to "put-out" causing cavitation. In the case of companies claiming higher flow rates, what is that based on?

Well there is a pressure differential in the system across the pump which causes the flow of coolant.

I see what you are saying but shouldn't the thermostat be open if you are having overheating problems? I can see this causing the jeep to heat up faster but with a properly operating cooling system once at operating temp the thermostat should open to control the temp.

Re: Overheating solved

Yes there would obviously be some pressure differential across the pump, but it can't be much. I think that would be the proper way to test pumps.

Re: Overheating solved

Having a similar issue with a 2 core champion radiator,high flow pump,180 tstat ,highflow water housing but it seems like the radiator will “heat soak” after about 30-45 min in the city with ac on in 90 degree temps,If you don’t don’t use the ac, she will stay under/around 210 during a 150 mile drive.

Re: Overheating solved

I have consistent temps up and down the tanks though and hoses are close to the same temp
