Can any one tell me what temp the disco runs at ?
for the pass 3 years its run between 1/4 and 1/2 way on the temp gauge and over the pass month or so as started to stay on 1/2 or just over and if towing climb higher can anyone offer any advice
Mine runs at half all the time, and I have no fan on but it ran at half before then as well.
Any number of things can cause this, from as simple as a faulty temp transmittor, to a problem with the head gasket I suppose.
Anyway lets start, is the water up to the level, clean with antifreeze in it or is it rusty, is the radiator ok, look through the grille and see if it's blocked up of if all the little fins have rotted away in between the water veins. Any water loss, fan belt ok, fan turning or just sitting there laughing at you, grab the water pump pulley and see if there is lift on it.
Other things, but gona cost you, faulty temp transmittor, thermostat, header tank cap, or head gasket starting to go.
Head gaskets are fairly common so it's down to you, if all the easy bits are ok then before you start throwing spares at it it might be worth getting a sniff test done to determine if the gasket is leaking a bit. I guess a temp transmittor is not going to burst the bank, or a thermostat but thermostats are fairly reliable.
Mine is an R plate and the radiator was rotten when I got it, all the fins were gone and it couldn't have been doing it's job well, I got a recon one with a larger capacity for about 140 quid, if you do this get new plugs for the thermostat and the radiator cos the plastic ones are total crap.
That's all I can sugest at the minute.
