My truck has 90,000 on it and I have no previous records. I'm guessing she's do for the flushing just not sure what I need. Sounds like a heated engine flush with filters and maybe tranny as well. Also what and where do I get filters I feel like the Ford garage will make some insane money on these paper filters? The truck see's a decent amount of gravel should I take other things into consideration?Thx.

 

You should have them do the tranny and coolant. Both should be done but you can just do one at time

 

The coolant is not that hard. It's hard if you follow the full procedure in the ford manual because they want you to flush with some chemical but you can do a good job at home. Go over to powerstrokehelp.com. Bill Hewitt is very knowledgeable on ford diesels and he has a you tube video with step by step instructions. The tranny though, assuming it's an auto needs to have heated fluid pumped through it and only the dealers have the equipment. And I've read that not even all of them have it so you should ask. It's pretty much a rule or at least a strong suggestion on this forum that you should use only the ford filters and motorcraft oil. They can be found on line at a pretty good price but don't write the dealers off. It might depend where you are. I'm within 25 miles of three dealers so the prices are pretty good. At 90K you should also deal with the differential (s) and transfer case if you have one. Based on 4 years of reading about stuff on this forum I think I'd rather fight a mountain lion in a phone booth than neglect the maintenance on one of these trucks. Hope this helps.

 

Agree with the mountain lion thing. Heard several stories of diesel trucks running strong in their old age due to proper maintenance. Graduated with the service manager at the Ford garage he "should" treat me right. He did recommend the diffs as well. Transfer case is a good idea. Pretty much if it holds oil or any type of fluid flush it.

 

I bet the cab has been off on a truck with 90k LOL therefore the coolant was changed...
