Am looking at possibily of installing an oil cooler, is there an article showing input / output locations on the K75 engine ?
many thanks AJ

No easy way that I know of to add an oil cooler. The big sump with lots of fins is how the BMW engineers cooled the oil in the brick engines.

Just drop the engine in without one, AJ. It's water-cooled. It'll still take longer to seize than the original engine even if it weren't. :giggles

I suppose you could remove the oil pressure sensor then route it back into the sump somewhere, but as others noted, shouldn't be necessary. Those old Fiats probably only weighed 1100 lbs, and that was before most of the body rusted off.

Ok was wanting to see if I could drop the running temp a little, will proably install a larger radiator, currently have the existing in a horozintal orientation, good scoop feeding it air from underneath, then larger fan drawing off the air.... just after 80-90mph the temp can rise... if speed reduces it does recover.
I have noticed with a new fiat temp sender inline in the radiator pipes that the temp on the guage moves up and down when off the accelerator, I have seen a few ocassional oil drips in the tell tale hole in the sump.... waterpump time ????

Isetta's had air cooled motoboxer engines so

Thinking about this, could it be related to the guage, in the fiat the guage came out of was on a dashboard I have mine located on the flat down by the gear selector, have bleed air out of system
