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?

ron Davis radiator with 2 spal fans that is what keeps it cool i tried 5 different pumps and 5 different radiators after shelling out the bucks for the Renegade radiator and fans which is really ron davis dual pass all aluminum and two big fans my v8 small block 427 stayed between 180 and 205 all day long. Oh i was using the Meziere 55gpm electric water pump located at the bottom of the radiator.

Is your radiator a 2-core, dual pass unit?

If you pump was located at the bottom of the radiator, does that mean it was pushing coolant from that location to the engine (lines out of lower rad to water pump then out of water pump to engine block)?

Yes it was pushing but i figured if it was at the lowest point in the system it could never starve for water. If you fill the system from the highest point and you have a good reservoir it will self bleed itself as it contracts and expands pushing air out and sucking water back from overflow tank.

I was not sure if there is a preferred placement... front or rear, bottom or top of the car.

I am looking at the Jegs 50 gpm unit that is designed to fit in a stock BB Mopar w/p enclosure/case which therefore; theoretically should fit in the Renegade w/p enclosure; perhaps with a bit of modifying.

I cant recommend enough (apparently) a water pump controller that will actually control the speed of the pump. If you just get a pump that will go on and off you'll find that it will overcool causing getting up to temp to take forever.

This is what I recommend. Read into how the LCD controller works.

Another option if you dont need an LCD (I love mine though, being able to see what is going on). This one does essentially the same thing.

If I could, I would!

To have that sort of granular (ok... fluid) control would be awesome! Just around double what my foreseeable budget would be!
