Hi, I am I need of some much needed HELP!
I have a 1999 Discovery TD5 that I bought about a month ago. It’s been running fine until a few days ago when it started to over heat and lose coolant. I stopped to let it cool down, filled it with water then carried on. After about 5 miles it started to over heat and had lost about 6 litres of water.
I can not find a leak, no loss of water when parked up, have had a land rover mechanic look at it who could not find a leak and has ruled out head gasket. He said that he has had another TD5 with the same problem. It could run 1000 miles without over heating, then lose coolant and over heat for no apparent reason.
The only drip I could see was from overflow pipe from header tank. I had the top off with the motor running, after about half an hour the tank was empty. But has now stopped leaking.
Could there be a crack between the in pipe and the overflow pipe in the top of the tank where the lid screws on?
I am driving to Italy in a month and need to get it sorted or get another vehicle.
P.S. before my Discovery could over heat and go in to the red, it lost power. Is this a safety feature?
