Which way round do the oil cooler pipes go?

I was looking at my oil cooler pipes whilst reassembling the front wing and think mine may be on the wrong way. My pipes go this way:
- engine block to bottom of cooler
- oil filter housing to top of cooler

Anyone know if this is the correct way?

Cheers

If they are the correct hoses I don't think they can be fitted the wrong way not that it would make much difference anyway!

From memory the bottom hose has a 90deg metal elbow section and the top not, and both hoses flexible section should only bend through 90deg not 180deg I hope that makes sense.....

Sorry I wasn't very clear, although it's a 300tdi 90, it is a retrofit and still on the original lt77 so the oil cooler pipes have been extended. Also realised I made a slight woopsy, the hose going to the bottom of the cooler comes out of the back of the oil filter housing, the one to the top comes from the side.
