Hi
I've a 1.3 panda multijet and have noticed dark stains above the water level in the cars coolant tank. The coolant is perfectly clean and so is the oil.

Is this a sign that the cylinder head may have blown in the past or that their are cracks in cylinder block? image.jpg


Notice the darkness above the coolant water.

No responses yet, so here's my penn'orth.

Have you dipped the reservoir?
If not, put a clean rag in, let it absorb the surface of the coolant water, then examine what you've got out. It may be nothing. It doesn't look serious, but photos are deceptive.

I have a diesel version and the reservoir looks similar to yours with a dark area above the coolant level, but there ain't nowt wrong with mine.

Any other symptoms apart from this?
