I’ve been working on locomotives for over a decade, and I keep seeing the same engine issues come up. Recently, I dealt with persistent overheating problems on a GP38, and it turned out to be a clogged radiator. Curious to hear what common issues you all encounter and how you tackle them.
Overheating is such a pain — I’ve had the same issue crop up on an SD40, and it was a corroded thermostat causing the headaches. Sometimes those smaller parts can get overlooked but lead to huge problems, just like that clogged radiator story — keeping an eye on those little guys during routine checks can save a lot of time and frustration down the line.
I’ve definitely seen similar issues — once, a simple coolant level check on a GP40 saved a ton of trouble. It’s crazy how neglecting those routine checks can lead to bigger headaches down the line.
I’ve wrestled with overheating on a GP39, and it turned out to be a simple issue with the fan belt being too loose. It drives me nuts how overlooked such basic stuff can be. Have you checked that before tackling bigger issues? Sometimes it’s the little things that save you a lot of time and money.
