I have a 54 Doblo 1.9 JTD Cargo. At the base of the oil filter canister is a housibg with 2 water pipes on it that bolts onto the oil pump. I assume that this is a small oil cooler.

Can anyone confirm that it is a cooler and where I could possibly get another one please?

what is your problem oil in water or weepage around the cooler,on the vws and hyundai they have a large nut seen when oil filter is removed metal oil filter,nut usually needs another nip up.

yes this is the oil cooler we had the same problem on 54 reg doblo we got one of 1st choice spares but be careful there r different types you have to match the numbers up
