Burbling from cooling system
I have just bought a 2007 Jaguar S-Type diesel and noticed a burbling sound from the cooling system. It usually lasts a couple of minutes then stops. The dealer says it is a common problem with S-Types and is due to a technical problem with the cooling system. Should I be concerned as it does not affect performance?

The turbos get very hot on this engine. I can't remember of they are water cooled as well as oil cooled. But 'burbling' generally indicates an airlock somewhere and you might be able to purge that by running the engine from cold up to temperature with the coolant reservoir pressure cap off.
