V8 cooling ideas., Only because I have the parts! Options

[BRAVE_HELIOS]

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?

I'd probably fit 2 maybe 3 fans. Find a fan the same dim as the small dim of the cooler.

There are tons of electronic surplus places, I'd hit them up first. Along with a place that scraps out computers. I've seen Dell towers have a fan that looks to be sized right, not sure of voltage though I's expect 12V
