If you're going to use a tractor ring hitch check that it fits the nato hitch. I was going to make a solid towing bar and none of the rings we use at work will fit a nato hitch.
It might be more than you want to spend but I took a chance and got myself these for work and cant really fault them.

I quite like the cheepo tiger ones. I've tried more expensive ones but they all last about the same amount of time. Being cheeper they're a little bit thinner so its easier to feel the filler.
Just watch what you're paying. I rebuilt a series gearbox/transfer box recently and my local bearing place wanted £120 for a timken bearing that I could get from all the usual places in the same timken box but with a bearmach sticker on for about £35.
Yeah its got instructions how to use it but a colour swatch type thing would have been nice for dummys like me. Like you say it looks greener but could still be blue if that makes sense. Anyway I tried it again this morning and it turned almost Land Rover green. The header still had water in but the plug in the thermostat housing took half a gallon!
Thankyou everyone for all your help.
Cheers gents. Looks like i'll just keep an eye on it and see if I really am loosing water. Its been idling a bit lumpy for a while and for the past week my cheapo chinese exhaust gas temp guage is showing hotter temps so i'm getting paranoid about things.
Got myself a sniff test kit because I think the coolant's dropping on my 300tdi Disco. Having never used one before can some one who has please tell me if this is a positive for exhaust gasses.
