Just fit one of those slim ones that was fitted to some old vauxhalls, if you fit it to the rad inlet then it will give extra cooling but the box will still work right as the temp sensors are for water.

Before is better, and the only filter is in the box and you have to take the box sump off Shocked

The reason for before is its a heat exchanger and the water warms the fluid so the box can work proper, if you put it after then it cant work proper.

Put a Kenlowe one on mine in front of the rad and plumbed into the feed to the internal rad cooler. Oil cooler gets hot in a short time after starting and I have never had any overheating when towing the caravan on petrol or LPG. I have recently also had to replace the steel pipe from the gearbox with a flexi hydraulic hose made up by Hydroscand with original end fittings as this rotted through and leaked oil.

Thanks for the tip, Blameitonthebuns! I might as well try that out.
