Re: I have hydraulic oil in my radiator, e70b
I am not familiar with that particular machine, but I believe it would more likely be diesel or motor oil, unless of course there is a water exchange hydraulic cooler. If there is, check that for a leak to the coolant. If not, I would check compression on each cylinder, and/or look for signs of a blown head gasket. Other possibilities are probably more serious than even that. I hope this is helpful.

the problem is most probably a failed oil cooler in the radiator tank
this allows oil into the cooling system that causes the engine to over heat
you can buy quality radiator/ block cleaner and flush the system yourself but the fix is to replace the radiator tank with the oil cooler inside
blocking off the lines will only cause transmission over heating
the only cheap option is a good radiator from a wreckers as replacing the tank can be almost as expensive as a new radiator
ring around and get prices that are close to what you can afford and make a decision from there
What does your radiator fill tank look like? When is the last time you changed radiator fluid? If you have an oil leak into the radiator, combination produces a jelly like substance that may be what blocks the screen. You may need a radiator flush and refill.
Step 1. Check radiator water level 2. Check fan belt tension 3. Use compressed air and blow through BOTH engine radiator and hydraulic radiators in the REVERSE direction of normal air flow. 4.Flush out engine radiator with radiator flushing additive. 5. Ensure that all rubber foam around radiators is gap proof, this keeps maximises air flow through radiator fins and stops hot air from engine from recirculating back in to radiators.
Evacuate the hydraulic tank and clean with kerosene.Get as much fluid out of the machine as possible. Replace Filters and if it builds back up with metal SELL SELL SELL it or your in for some big money repairs.
The seal units at the turn table are worn or there are grooves worn around the sealing ring.. It is common for this area that is subject to such movement in the worst possible conditions of dust and other contaminents
First I would check the oil to make sure that the water is not leaking in through the head gasket. If the oil is ok, then you can go to any autoparts store and get some radiator stop leak. This will fix small holes. Flushing the radiator will probably not do any good.
remove the one end of the hose that is from the rod end of the clylinder.
two ways you can go here. either: detach the one end of the hose that is attached to directional control valve and leads to the cap end of the cylinder and place the end in a pale then retract the cylinder by physically forcing the rod back in and all the oil will drain out of the cap end into the pale and the rod end will fill with air.
or u could hold the directional valve in the position to let the oil flow back to tank while physically forcing the rod back in. the oil in the cap end will drain to tank and rod end will fill with air.
drain the tank of oil.
if you wanted to be extra thurough remove the remaining lines and drain the oil out of them.
reattach all lines.
replace oil filters/strainers. should be one on the return line going to tank. and one on the suction line before the pump. But there may not be a second filter.
fill tank with new oil.
extend the cylinder using the pump. allowing the air to bleed off the rod side. may chatter at bit while extending. if excessive chatter remove line end to allow the air in the rod side to bleed to atmosphere and continue till fully extended.
reattach line. probably a good idea to run a couple cycles.
and repeat the entire process for a thurogh flushing.
! note: dont be dissconnecting lines with pressure in them or while the system is running.
! note: be sure to have enough oil in the tank so the pump is not sucking air. this will eventually cause unrepairable damage to pump if sucking air for too long.
i just wrote this off the top of my head and ive only worked on industrial hyraulic systems and never on a log splitter before so just keep that in mind. hope it helps
