Coolant in oil after injector swap
Alright everyone, this is the last thing I have to resort to. This is my first experience with a diesel so please bare with me. So a few weeks ago I changed the injectors on my 1993 7.3 idi non turbo. While pulling out my old injectors the farthest one back on the driver's side was so stuck I...- Krector88

Need advice on a 6.9 purchase

I’ve never had any real problems I’d say, just minor little fixes here and there. Currently, I am having a coolant problem, or so I believe. I drained and flushed all the...- Stu Bailey

Extending coolant change interval (switching coolants)
Well here's another coolant question for you all, maybe a stupid one but i haven't been able to find an answer. I've done lots of reading but I'm still unsure of what flush intervals people are doing (if any) when they switch to other coolants like CAT, fleet charge, or Fleetguard Compleat EG...- eldonderino
