    X series diesel owners... Check you radiator hoses!

    My '13 x758 developed a coolant puddle under it one day, so I investigated. As I was checking over the hoses, I found the culprit. A misplaced and loose upper clamp on the lower radiator hose at the thermostat housing was it. However, I also found the head of a bolt on the front of the engine accessory drive cover, just in front of the fuel pump, had rubbed almost completely through the same hose. So in the interest of saving someone some money if they're near the end of their 4 year/700 hour warranty, figured I'd give you all a heads up so you can go check. I was installing a block heater anyway, so instead of screwing around taking the tractor in to the dealer, they just gave me the hose and I brought my old one in, installed it myself. Honestly, it takes longer for the coolant to drain than it does to change the hose. But one thing to note; I did end up trimming about 1" off the lower end of the hose. The new hose was slightly longer at the bottom and left the first bend too close for comfort to the motor mount bolt. The hose in question is #3 in the link. (crappy picture, but it's that one.) Also of note, the new hose doesn't really fit any better than the old one, so I positioned it the best I could and ziptied it in 2 spots to the main harness running down the radiator shroud. First pic I attached is the hose in reference to the engine. Second pic is the damage and bolt head.

    Edit: Sorry, just realized it uploaded my pics rotated 90 degrees.

    Maybe you can "armor" it with some of the convoluted loom (if you can find large enough diameter)

    You are not alone my friend, I had a leak too and found all the hose clamps were not tight enough to hold a fart! I moved the radiator hose away from the bolt and put a piece of old radiator hose around the one I moved with two plastic zip-ties like you did and I believe it would have been a short period of time before it wore thru.. Mine may have been worse because the dealer connected a cab heater and I think they took a break and forget where they were! Great post.. and thanks for posting it. I mentioned this last winter about the hoses not being clamped enough, but good to see it again as a reminder.. If you have a new JD check everything you can including fluids and engine oil!

    When I had my X748, hose clamps were all lose and started leaking. Became an annual maintenance thing.

    Loose hose clamps have been an on going problem not only on the L&G tractors but also on the larger AG tractors up into the 6 series. We beeched, griped and complained to lil avail. Now we just tighten them up at Pre delivery. Run em til hot and snug em up a lil more. We dyno all 3 series and above to check HP and cooling system, so we tighten at that time. X series get an hour run at WOT. Leak check and snug hose clamps. No problems so far.

    The hoses must just shrink when new, no matter what machine it is. After I bought my motorcycle, same thing, it started leaking antifreeze. And yep, it was a loose radiator hose clamp! Hasn't leaked since.

    I figure I'll run mine a while (if we ever get any damn snow to move) and make sure that hose is all set with placement and the clamps are still tight. I figure if it saves someone a dead tractor in the middle of their yard or driveway due to losing all the coolant from this hose, it's worth the advisory to check! I've looked at the hose a handful of times and it wasn't until I pulled it away from the block and twisted it a bit that I could see the damage. It was hiding good!
