Thanks, it seemed to be engaging CDL as there was a noticeable difference to "the drive", also as it was harder to engage at first & had to work the stick a bit but I did feel it engage on the stick so to speak.
RE the overheating, I went to the local LR yard here in Hervey Bay (nearest other one that's not new cars only is in Gympie over 200k's away) to get some info on bottle cap & he was in a bit of shock. That's not a LR cap, I don't know what that is, he reckoned (it was yellow) so I bought a new 16psi one. I don't know as yet if there is any difference but one thing I did notice on the short trip there & then back was, the water level in the bottle never changed level when checking whilst hot with yellow cap. Changed caps for trip home & the water level in the bottle actually rose when hot then dropped back down when cold (took caps off with utmost care) with new black one.
So here's hoping that little (LOL) prob might be fixed, touch wood :D
