Hey guys, new to forum and just bought a 1972 L260. Tractor runs great and everything works good except for a very small water leak coming from behind the injector pump. Question is there a freeze plug back there that could be leaking or what do you'll think it could be? It has the Z1300 2 cyl engine. thanks for any information

I do believe there is a freeze plug behind the injection pump, can you past a picture of where you think it's leaking?

Water leaks can be very deceiving. Auto Parts places now sell a product you can add to your coolant that will glow under ultraviolet light. Add to coolant. Clean the !@#$% out of the engine first and follow directions on best way to use it to find leaks.

For example you can have a tiny leak at say cylinder head that drips toward and collects at top of IP. This slowly works it's way around it combining the small amount of coolant leaked out enough to form a larger easily visible water spot that makes it appear it is leaking from underside of IP, while all along it is actually cylinder head leak from above.

(example not specifically related to any Kubota engine)

OK thanks for the replies.I had a chance to take a closer look and found that there is a small hole (about 1/16") drilled in the block about 1" under the freeze plug. What is this hole for and why would water be leaking from it? Could it signify a bad sleeve O-ring or cracked block or what?
