i have a 93 mark 8 had it for about 2 months now yesterday it started overheating really bad coolant was all over the engine ,so i got all the air out of the system(i think) now when i drive it its fine for about a mile and a half then the temp shoots all the way up, stays there for about a mile then goes back down to normal. And also im losing coolant somewhere ,it was full now the resovoir is almost empty.any help would be appreciated. thanks
