Greetings LT people,
Had an incident with my 2000 LT with 70K on the clock. Was in Sturgis last summer going threw the Black Hills, pulled over for a rest and noticed 'smoke' coming from under my seat. Lifted the seat and the nipple from the overflow coolant tank was shooting out coolant, and it was spilling on the exhaust causing the "smoking" sensation. I do change the coolant about every 20K, and the level was correct at the start of 2013.
The motor was not overheated and I would say I lost less than a cup of coolant. Checked it over and have done nothing since, including not adding any more coolant. Have been to two BMW dealers and they did not have an idea on what may have been the problem. No problems since then, but it is wintertime now so good time to consider any possible fixes.
Have you had this happen? Did you do anything? My only thought would be to change the radiator cap as perhaps it is weak.
