Xnke Posted August 10, 2013 Share Posted August 10, 2013 They're hard as hell to find around here. Everyone wants a bill or better, and they all look a little rough. I did find a few mercedes W124's with nice Behr oil coolers though. Too bad they have quirky M22x1.5 compression fittings on them. They're a little big for the location on the car; but I have it all worked out with the 24 row Long cooler. I ducted from the front air dam brake-duct cutout to the wheel well with cardboard; and I'll be fiberglassing over the cardboard to make the finished duct. The low-ish neutral pressure zone in the wheel well and the high pressure air through the brake duct hole should direct air through the cooler at any speed over about 10MPH, and the hose routing is simple and direct.

peej410 Posted August 10, 2013 Author Share Posted August 10, 2013 Progress report. 80deg day back roads and highway. While moving coolant temp was 180. Sitting in bumper to bumper for 20min 205 was coolant temp peak. Oil temp peak was 180. Cruising was 140. I will need a thermostat for street driving!

peej410 Posted August 17, 2013 Author Share Posted August 17, 2013 Picked up a Derale thermostat and some more brass fittings. Ill install it tomorrow and report back. Quote Link to comment Share on other sites More sharing options...

I did that using a Niagra unit and eliminated the air flow issue. Johnc: Where does a person purchase the Niagra coolant/oil heat exchanger? Pictures? Description?

peej410 Posted September 3, 2013 Author Share Posted September 3, 2013 Not sure about the niagra cooler... Report back. Took it to the track on a 80deg day and ran multiple 20min sessions. Peak oil temp was 190 Peak water temp was 205 (in pits after run) Oil temp is at the sump. I am debating moving it when i go dry sump. A lot of people say after the cooler. Any input?

In retrospect after purchasing an aluminum radiator with integral auxiliary trans cooler, should have paid more attention to cooling engine oil. The input and output fitting on my radiator are likely TOO small for good engine oil flow. Have you used niagarathrem engine oil heat exhangers that are embedded with a radiator? GM has used this in heavier duty applications. It would seem that engine oil and trans fluid temperatures would rise along with coolant temp such that there is more uniform temperatures across these assemblies. Your comments please. Thanks again.

260DET Posted September 13, 2013 Share Posted September 13, 2013 Pic of mine mounted as previously mentioned. Power steering cooler on the left forms part of the duct to the engine OC. Quote Link to comment Share on other sites More sharing options...
peej410 Posted September 16, 2013 Author Share Posted September 16, 2013 Update. Even with a thermostat the oil barely breaks 180f. I am going to relocate the cooler behind the front valence under the rad duct. Hopefully air flowing through the radiator from the rad fan is enough to keep it cool when stopped.

Slicks hurl rocks at the back of the headlights Easy. What you can't see is the expanded mesh at the back of the coolers. Basically fits in with the OE guard/fender shape.
