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!

I wanted to give an update on how I DRASTICALLY improved the cooling efficiency of my car. No electric water pump or 4 core radiator needed.

My engine originally came with an oil cooler installed (Chevy pickup). Unfortunately; the cooler was ruined after the truck wrecked. I kept the oil cooler adapter installed on the block and just capped off the ports on the adapter.

Fast forward years later and after combating a constant run hot situation on my car; I decided to go through my parts bin and install an oil cooler I had from another project.

What an incredible difference! My car is now running a consistent 20 degrees cooler... without touching anything else! It's a miracle I tell you!

Anyway; I have it mounted on my engine lid right now. Is there a better place to install it for more efficient cooling?

More details... Right now, I have the fan set to come on at around 170 (I will be adjusting this). Driving around town or at freeway speeds, the temp has yet to go beyond 185, which is OK with me, especially compared to what it was before. Twenty degrees higher and it was fast approaching the danger zone!

I'd put some muffin fans under the cooler blowing upwards. Maybe wire them into the rad fan circuit.

These fans are those square fans found on computers and other stuff.

That's a pretty good idea!

Think I get a noticeable temp drop by doing so?

Checked out DigiKey's website:

What do you suppose a good CFM rating would be for a couple of muffin fans mounted to my oil cooler?

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

Man, your cooling system is getting complicated. I hope I don't share the problems your having with my SBC build. (IMG:style_emoticons/default/confused24.gif)

LOL... I look at the cooling hoses going all over the place and say the same thing!

Granted, I could tidy it up a bit; somehow but everything there is what's needed... expansion tank; heater core for our cold Idaho falls and springs.

It will stay like this for now. Next summer; if the coolant temps get too high when it's 100 degrees out; then it will be time for a 4-core rad and electric water pump setup! But considering where I came from with my constant run hot issue; the addition of the oil cooler definitely made a huge difference!
