      December 19, 2016 at 12:04 pm 6BTA 370. Currently the coolant is ES Compleat EG. It was changed 5 years ago, approx. 800 hrs of running in those 5 years. I understand that the B series engines are not coolant sensitive, parent bore engine and I could have used regular green anti-freeze but that is not my question. My question is how long will the coolant last OR should I change now?Ā  If you look at the specs for the ES Compleat they state something like 1,000,000 miles or 40…

      November 29, 2016 at 2:28 pm I have had the SMX raw water pumps installed on my 6bta -370 for about 5-6 years now. At what point should I think about replacing the cam, seal and bearings? I have replaced the impeller once and will do it again this year. Although last time after 2.5 years they still looked like new.
