    still find it odd that they went U/S together though Muz ...... I bow to your superior knowledge though Boyo
    If it's got tracks, wheels, t*ts, or an engine, at some point it's gonna give you trouble!!

    I didnt mean that exactly, although they do sit right ontop/beside each other so when one overheats as they do, it affects the other, or, .. if you've caught the first one failing,early enough some people just fillet it and only leave the other service working. Not sure how they were wired, but they are isolated .

    That machine could be ordered as fast speed travel only, meaning just one relay, and/or XTV which has expanding tracks and fast speed travel.
    Please don't PM me for plant advice.. thanks .. Post in the forum where I will gladly help, as will many of our contributors.. as the info and responses will help everyone else, which is why we exist

    Sorry for any confusion caused here chaps:

    The expanding tracks failed a while ago, but the variable speed tracking stopped working just last week.

    Am currently awaiting delivery of a new water pump to hopefully solve the overheating issue (which is stopping me from using the machine) before then looking at the other two issues. Meanwhile I am trying to find a source for the solenoids so I am suitably prepared.........

    Before anyone says that I bought a pup, it was all working when I bought the machine 3 years ago, since when it has lived here on the west coast about 40m from the sea. This can be brutal on things like plant, trailers etc

    Nah were just having a natter about the barstewards .. worth doing a lot of reading here about them .. is it really overheating (blowing out steam) or just a false shut down caused by a commonly faulty sensor and ECU ?

    Blowing out steam from the expansion tank, at which time the water starts to bubble - so deffo overheating. Engine keeps on running OK as I have caught it when it starts to steam (thus far). SWitch off, leave to simmer for c. 20 minutes, top up water again and then might get another 6-8 minutes before steam restarts.

    Squeal from what I thought was the belt when the engine is running has been traced to the water pump - almost exactly the same noise as we get from a failing water pump in our boat engines (which is sadly all too common)

    Thermostat seems to work OK as per maintenance/repair/service manual specs and water pump is rough as the proverbial. Only time will tell if my diagnosis (of this issue) is correct.

    Muz - can you please point me to where the solenoids might be located?

    Many thanks again

    It should shut down automatically if the sensors and ECU are working correctly .. I'd check the radiator is clear , I mean totally see through clean, you need to pop out the oil cooler to make sure its crystal clean everywhere, they choke up real easy and that would cause your problem, if it isnt a failed pump, or an air lock to the heater matrix not allowing the pump to circulate

    will be a post elsewhere here about the solenoid positions, have a search
