Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I'd get it changed ASAP, the tank is around £90 from Eurocarparts then add a couple of hours labour and coolant.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

Edit: problem now sorted [ ]

POST 2Original post

Check your coolant expansion tank for reduced coolant levels. They are prone to hairline cracks at the bottom, or for the cap to leak (if it's the cap you might see white residue around the collar).

POST 3 / ORIGINAL POSTEROriginal post

Thanks Rodney, I've done some research and reckon this is the problem. Would you say the car is still driveable as long as I keep a close eye on the coolant levels?

POST 4Original post

I'd get it changed ASAP, the tank is around £90 from Eurocarparts then add a couple of hours labour and coolant. Mine cracked on my C4, steam poured out of my tank as I was driving along as air bubbles entered the system. You don't want to be towed away or risk engine damage.
