Ive just had my car serviced at a dealership . When it went in the coolant level was just below the min level when cold , it had seemed to go down slowly over the year since my last service . I popped the bonnet today and the dealers have filled to the maximum line. , question is .
1 Is a slight coolant loss normal over a long period of time , is it "finding its level"
2 Should the dealer have topped it up and would they notifiy me if there was a leak
Cheers all
