Auxiliary oil cooler, An alternate location Options

[IronHillRestorations]

25 years ago when I put a 3.0 SC engine in my 914, I understood the need for additional oil cooling, but I didn’t want to cut up my frunk, or run 26 feet of oil lines. My car was a street hot rod, and really didn’t plan on doing track events, so I didn’t need the maximum possible oil cooling.

My solution back then was to put a 25 row Mocal cooler with a fan sandwiched on it in front of the right rear wheel, on the opposite side of the car from the oil tank. This worked out well, and neither I or the current owner has seen oil temps out of range.

I have another street hod rod in the works and since the right rear quarter panel was removed for rust repair, I decided to revisit this alternate oil cooler location.

After measuring, mocking up, and some head scratching I figured a 34 row 234 matrix Mocal cooler would fit. Here’s what I’ve come up with.



To test fit a Spal puller fan, I taped it to the cooler.



Two holes drilled for the front bracket and one weld nut for the rear bracket. 3 M8 cap screws are more than enough to secure the cooler
