When we go to the city with one of the new 550Js we spray on a small bit of diesel fuel every couple of hours dirt releases better some of the guys use salt on the undercarriage but that is to much corrosion for a 14000 dollar machine as far as I am concerned Digitup.

If your block is cracked on a Deere engine it will leak to the out side if head is cracked or gasket pushed out of shape then it may be internal leak into engine oil the best thing to do is get a rad tester and pressure up to around 15 lbs that will find all leaks fast in engine and rad .My old Snap...

When the engine is ran on straight water the sleeves get eaten out or pit around the bottom the first thing you notice is antifreeze in your motor oil when the sleeve seals leak it is always at the bottom because of the combustion heat .It is a weak spot on a lot of sleeved diesel engines if you do ...

Cheap at twice the price! Hopefully the water in the engine hasn't done too much damage. Check it out, don't change the motor oil before you put anti-freeze in it. If there is anti-freeze on top of the oil the next morning, and the blocks not cracked, you still got a deal.
