Coolant leeking, cant pinpoint it but dripping when parked after journey under car protective shield under the radiator, seems to be nearside but could be just on a slight angle when parked. When more coolant is added it's just dripping out when engine cold see pics red coolant
I'll prob just take it in the get it looked at but is this common in this model??

Have a look at the coolant cap seal (WHEN COLD!!) :LOL: and see if it's split. The Insignias' are notorious for it (and all Vauxhalls of that sort of era, my 2007 Corsa had the same issue). If it isn't that, then check the Coolant reservoir itself for any obvious splits (whilst cold but also try it when hot because some cracks don't leak until the system is under pressure.

Literally a 20p part for a new seal IIRC. If not available then a cap's about a fiver posted new.
