Early C/F Oil cooler

[auyt]

Does anyone know what the optional oil cooler was for S3 Chassis, or at least what fits?

The mounts have holes 8” apart which doesn’t match any oil coolers I’ve found, and rather than move the mounts, I thought I’d investigate what the original fitment was fist, I using -10 fittings.

The oil cooler is mounted on 2 brackets in front of the radiator. this one will fit https://www.merlinmotorsport.co.uk/p/mocal-oil-cooler-10-row-10jic-115-m-oc10n-10jic edit to say that if you have an old rad where the hoses go trough the rad it might need different brackets

Magic thanks for the link, I had a look in the Mocal listing and didn’t see that size.interesting Burton’s recommend rubber mounting it, given the distance from the motor I would have thought it not necessary.

Never seen it rubber mounted on a Caterham.

In all the pictures Ive seen the solid mounted, my thinking is as long as the hose vibration is isolated from the cooler that removes the probability.

Classic aircraft engines the coolers are solid mounted to the engines but they do have diagonal bracing on the cooler. I've ordered a Mocal cooler, and even though I wasn't going to run one, its a OH well the options available and its easy to do now.
