Diesel oil cooler

[Sunny43.5]

Hi asking for a friend he has a 2012 T5.1 2 litre turbo and has a water leak around the diesel cooler on the front of the engine . Has anyone changed one and what sort of job was it to do . Thank You .

What do you mean by diesel cooler?
I've got a 5.1 (single turbo) and the other things on the radiator carrier are the aircon condenser and the intercooler.
The radiator is the only thing with water/coolant in it.

Its at the front of the engine just near the oil filter alloy thing with cooling fins around the outside .

looks like an auto water/oil trans cooler. My advice, get rid of it, and replace with an air/oil cooler. It's an auto trans heater. Your auto oil runs at best, 90C. I converted to an auto air cooler after the gearbox was rebuilt at 160K( seals/ o-rings had gone hard due to oil temps IMO, damaging gearbox)
On the T5 the long flat diesel cooler is under the vehicle behind the passenger seat

Ahh.......I have a manual which explains why I have never seen such a thing!

Yes that was on my older T5 under the car directly behind the wheel which goes off road first , ours got punctured leading to diesel spraying out onto the road causing the van to do a great version of a drift racer when we turned onto a main road . We didn't see it was leaking until then , next morning just fitted a bypass hose and all was good .

so, is it an auto trans cooler you're asking about, a diesel fuel cooler, or an engine oil cooler(which i don't think a T5 has.)?

Where do the oil pipes from it go to?

Its not my van but is the same as ours and as far as I know its an oil cooler on a diesel engine , my bad as I posted the question using "diesel " oil cooler , so that's why its gotten confusing .
