Can anyone help with coolant issue?? Had head gasket done last week (££ ouch)..... drove fine until yesterday.....car hadnt been used 4 24 hrs....went to go out yesterday to find coolant leaked over drive. Filled it up, did short journey, empty when i got home. Filled it ip again, turned on engine....all fine....no leak. Get up this morning + coolant all over drive again.....any ideas??
