Hi guys,

I recently bought a used 2012 X748 with 271 hours on it. When I picked it up the dealer said there was a coolant leak but they tightened up a hose clamp and felt they fixed the problem. Over the next couple days 5 drops of coolant was visible on the deck and dripping off a bolt. The leak then went away. I have now put 4 hours on the machine and can smell anti freeze and once found 3 drops on the deck. I was talking to my neighbor today and he has a 2016 X738 and his has been leaking coolant also. When I lifted the hood he noticed a very slight leak at the top left hand side where the tank is crimped. We then looked at his and sure enough, an identical leak on his much newer machine.

I will call the dealer but want any info regarding if this is an issue with these crimped plastic tanks.

Can you post a picture of exactly where on the tank you feel it is leaking?

The part numbers show different tanks of different styles for the two machines you are describing and they are not interchangeable according to what I see. Chances of both different tanks have issues would seem quite low......

I'm sorry I dont have a solution for you but would like to give you heads up. I bought a x595 that had a coolant leak. When i took the radiator out it destroyed due to coolant dripping down to the bottom after being dumped during the filling process. The aluminum ears that crimp the top and bottom plastic tanks together were corroded beyond saving. So be sure you get that leaked fixed and ALWAYS, ALWAYS be extra careful when topping off the radiator and clean up and antifreeze spilled during the process A.S.A.P. I didn't think Antifreeze could be so corrosive, man was i wrong. Maybe pressure check your tank, maybe the cap isn't working correctly. Good luck hope you get it figured out.

I seem to recall someone posting a while back about an issue with the X700 machines. It seems under certain conditions the frame can flex (twist) and it can be enough to damage the radiator. If I remember correctly, the issue was noticed while mowing a large ditch and as they would transition from the left side of the ditch to the right side of the ditch the tractor frame would twist noticeably.

Anyone else recall this or was I dreaming?

My 2006 x748 has had a slight leak for probably 10 years now:hide: I might finally get a real copper and brass radiator made for it. I never wanted to spend 400 bucks for the same aluminum and plastic replacement

I would buy and install a real conventional radiator in a heartbeat if that would solve the problem. I can't see replacing with the same thing that has a problem. It really is suspect that my neighbors much newer machine has the identical issue.

Here are pics, the leak is slight but I sure can smell it unless there is another source too.

Bolt looks loose in the last photo to me
Heck I'll check anything tomorrow when I am in the garage. :thumbup1gif:

Don't know why that would make the crimped part of the radiator leak though.:banghead:
