Ran out of gas in the 110 today and I'm on petrol so decided to get the Disco done today whatever as although the V8 goes very nicely on petrol, it only does about 9mpg knocking about.
So, soldered me headlamp connections on, all nice and bright now, and refitted the grill. Then primed the lift pump and she started first turn.
Thought I would test the new temp sender unit and make sure the motor didn't leak anything so took her for a test drive, Result, after about one mile the temp gauge had moved off cold and the heater was warm. After two miles the temp gauge was normal and the heater was nice and hot so I stopped to check under the bonnet. Aimed me lazer temp thingy at the head and it was 65 to 85 degrees depending on where I pointed it, the thermostat housing was at 75.
Set off again and as I drove along the temp gauge contiued to rise until it was near hot. All this in about 3 to 4 miles so I stopped to check again and all was well. The header tank was cold and the rad just warm and the thermostat housing was at 65 degrees after ticking over for about a minute but the gauge stayed on three quarters.
Now I know it isn't overheating and it's better than it was at getting warm so I have sorted the cooling system and heater out. Thing is what is wrong with the temp gauge, is it the new sender because the old one hardly moved off cold, or is it the gauge?
