I've noticed this winter my John Deere 4200 has a very very slow coolant leak. It only leaks when the temp. Is below zero. And this year where up to about 50 so far,( and tonight March 3 it's suppose to get to 15 below, a new record. ) I use prime airily in the warmer months. I haven't looked...
How do you check glow plugs & block heater on a John Deere 4200. I got it started at 15 below zero ( barely ) I'm thinking it should have started a lot easyer. My diesel vw sits at work 11hours a day not pluged in and it starts no problem.
