Oil cooler location on 2004 Berlingo Van 1.4

[Sharkie]

On your valve cover image, right rockers look a bit toasty.
Probably overheated on that part. Remove the termostat for now as well and flush whole cooling system a lot of times. There's oil everywhere.

Can you tell me what is the most effective way of cleaning the face of both the head & block

cleaning attachment for power drill.

Usually it's done by flat tool that doesn't score stuff. https://i.ebayimg.com/images/g/8XEAAOSw ... s-l300.jpg
But you need to grind down the edges.

Head bolts can creak and groan spectacularly when being removed. They can also give up a very distinctive aroma as original thread-sealant meets the air. Takes something to snap one of those!
