A nice upgrade to a diesel T3. Generally underpowered, those little engines have a hard life in a van. An oil cooler won't make it go any faster but it will keep things a bit more sane when booting it up that mountain in third gear!

It's a piece of mind thing really. It's not cheap but I'd recommend it to anyone who's still got a sound engine and want to keep it that way for a while.

Got the kit from Brickwerks.  Great quality stuff as usual from those guys and a straight forward to fit too.  There are some fitting notes here: https://www.brickwerks.co.uk/index.php/diesel-oil-cooler-kit-fitting-notes/.  Running the pipes under the van was a bit of a bitch without a ramp but doable.
