These are some photos of the small coolant hose that runs to the oil cooler on my 2.5 CRD. I was quoted £100 plus by a Chrysler dealer. I found a used one on ebay. If you have to get someone to make one up, the following measurements might be of use: Inner diameter of the hose: 15mm Outer diameter of the hose: 24mm (this may have stretched a little bit) The wall thickness of the hose seems to be around 4mm Height of the U if you stand it on a table : 62mm Width of the U : about 60mm Hope this helps.
