I changed the oil today on my beast, brought it around back to wash it and left it runnin.. honestly I forget it was runnin, washed my car and it basicly idled there for a good 30-40 mins.. After washing, shammying etc, I backed her up and she started puffin white clouds. Got someone to verify it was coolant. Now she burnt it for about half a KM then went away totally. shes been on and off about 5 times since then and ive put about 40 kms on her since and theres no Smoke, lots of coolant in the rad and the overflow is still full. Ive never had a prob with smokin b4 or now that I think of it, left it idling for that long. What do you guys think it was?.... or is?
