Hey Guys,

I have a new-to-me 2008 F250, 145,000 miles. Bought it with a slight coolant leak at the horizontal EGR cooler supply. I got under it and tightened the clamp where the leak was showing one day after work last week, drove home 20 miles, and parked it in the driveway....I then noticed coolant pouring out of the front of the vehicle when I got out. Inspection shows it to be the original radiator hoses with black end connections.The lower one (driver side, #11 in the diagram) is leaking at the top where fluid is pushed into the coolant pump.The hoses were replaced on the truck under warranty but a long time ago, before the updated parts and the 11-12-04 TSB. My truck sits until I get it fixed, as I lost about 1 qt. of coolant as I watched it drain and inspected for the the source. I want to replace all of them to the newest upgraded versions.



I searched around, but could never find an answer to what parts I need to order for the repair? I know the two hoses, but what about the other half of the lower radiator hose (#13)? Also, do I need to order the clips and seals (#10, 12, 14)?

I also plan to do the "full-day" flush procedure....but I have to find the write-up I read last week. Something about getting a Cummins dealer product "restore" for cleaning the system with? And also I need to find a place to go with 30gals of contaminated fluids and water! What do you guys do with it all? Or should I follow the Ford TSB 10-7-5 for flushing the system? Anyone on here done either of these or a different method? How did it work for you? Any pointers?

Thanks for all the help so far!

MT


p.s - anyone in the area that wants to help, free homebrew will be available during the procedure.

 

I was also thinking of adding a Coolant Filter...any suggestions or thoughts on this? Brands? Mounting locations?

 

Anyone with some pointers? I want to get this stuff ordered so I can get the truck back on the road.

Thanks,

MT

 

Similiar issue with my 08 F-350 but it was the top hose. I elected to replace only the O-rings at the block and radiator. No leaks for past 40,000 miles. I ordered O-Rings from FOMOCO which are different material than original. I drained system, radiator drain and two plugs aft on block. One is real tight to starter which needed battery disconnected in order to not arc to starter pos lead. Hope that helps
