Defrosting Unimog air tanks?

i sold the mog but i have a merc lorry now, any savings would be great mate:thumbup1:

The ethanol injection unit (if fitted) is next to the unloader valve and has an on/off rotary valve, air dryers filters (change every <2 years) live just forward of the battery box (if fitted) on MBU/SBU mogs.

 

If you have non of the above then you undo the main pipe at the unloader valve to the tanks then add 250ml of ethanol to this pipe then reconnect it, then start the mog and build pressure, then activate the brake peddle 7 or 8 times then the handbrake 2 or 3 times to distribute the ethanol threw the system, this should be repeated every 2 or 3 days of cold weather

 

As for single & twin line trailer valves, 4-way protection valves, unloader valves etc they can be got from any commercial/HGV equipment places, its quite ironic that new complete valves are not much more money than the valve diaphragm/recon kits, e.g. the last twin line trailer valve I got for a u1500 was £151 with the VAT yet the recon kit was £116.

All running fine now thank you all. i just fired her up with the intention of looking at the problem but she primed the system straight up. i will drain moisture etc over night and get back to using her this week weather dependent.

glad to here she is running, but i would definately get the pipes and valves cleaned out asap, it will save you a fortune in the long run, any pics of the mog mate?
