I checked my coolant expansion this evening and saw accumulated around the red thing, lots of tiny bubbles. I also felt like the coolant had a slight film to it, but I had stuck my finger in the expansion after cooking with oil earlier and I've never ever noticed that before, so I don't think that's an issue. It was more the bubbles.

Here is a pic..



So I guess what I'm asking is, does anybody else notice a sort of sweet fuel smell on cold start from their M62? And should I be worried about the little bubbles?

Obviously I need to determine the source of coolant loss, but as I say it's very minimal.

All opinions welcome

Whens the last time you had your system flushed? The color looks odd?
