I have a 2008 vectra c cdti estate with air con and I think clare control.

My question is yes the weather is a lot warmer and I have noticed the temp gauge increase,

Should the radiator fan run all the time as it got to 80 - 90 and never kicked in once, on driving it today saw it going between 80 and 90 on a motorway run but when warm and looking under the bonnet the fan not running.

Yep I haven't a clue there's plenty of water in coolant bottle but just wondered about fan.

Hear from u all soon
