I bought used L4350 from a guy in Illinios this past week end and did not inspect the new battery he put in (a very large NAPA Commercial grade battery with nothing more than a bungee cord to hold in Place). After less than 20 minutes of use I was digging around stump and the battery flip over in a shorted out striking the oil cooler causing a leak and fire. Short story is I have removed the battery and oil cooler and their was little collateral damage. I need to know how to bleed the system after I replace the oil cooler and I want to test the radiator to make sure it was not damaged during the fire. Can I close off the hydraulic line for a radiator idle only test for leaks without the new oil cooler installed? THX

Welcome to OTT, that is one heck of a story! Wow!

You do not need to bleed the hydro system, it's self-bleeding, you just need to operate all the controls a few times to get the air out.

No you cannot "close off" the hydro lines and then start the machine, that will send the system into relief and can overheat the fluid if it stays that way. In an open center hydraulic system the fluid flows constantly.
