Sludge in coolant reservoir

Topic starter

Hi all I have an Opel Astra GTC 2012 model with 140000 km on the clock. I have had coolant issues such as a bubbling coolant to the point where it spits out of the overflow. Now I’ve noticed that there is a black sludge build up on the side of the coolant reservoir. The coolant is however perfectly red/pink in colour and doesn’t seem as if it has been mixing with the oil. Please advise if you know what could be the issue.

Check the head gasket.

Those are all textbook symptoms of a failed engine cylinder head gasket.
