I think I have pretty much exhausted the ways to make a mechanical Chrysler/Renegade water pump setup run as efficiently as possible.
At this time; I do notice that at idle, the engine temp creeps up but as soon as I give it throttle; the temp comes down by almost 10 degrees... it stands the reason since at higher rpm's, there is more water flow. Now for the ideas... I have a spare aux electric water pump from my 545i. BMW uses the pump to assist in pumping coolant to the heater core. It is a small unit and I am sure the flow is low compared to the standard electric or mechanical water pump. Could I integrate this lil ol electric unit to flow a more consistent rate, even at idle? Would it interrupt the flow from the mechanical w/p? The other item is the oil cooler that came with the engine but I have yet to install. Would this help cool the engine down and by how much? |

Here is a pic of the aux pump across the upper rad hose, I could be tempted to place this on the lower hose. This is a bit of a last resort hack and would need testing. What temps are you actually getting?
Your charging system is dropping off too much, prop that up and the cooling issue may go away. If you have a largeish battery charger, hook that up while at idle , don't rev the engine and see if temps drop. ( The fan will be running faster but water flow will be the same. ) I'm also wondering if the temp gauge is responding to a higher voltage and making it look like the temps are dropping. Is you fan a push or pull? Does the fan move air across the entire rad? A push fan that is too close to the rad will have a dead air flow spot at the center of fan and will reduce cooling.
