I'm new here and don't know alot about cars.
in may i brought a focus mk2 1.8 tdci its on 120k thought i had a bargain until the journey home.
Came across it on ebay, spoke through message and was stupid enough not to go through eBay and pay cash on collection so no chance of getting any money back obviously. took it for a spin and everything seemed fine gone through all gears gave it a bit of a thrash, looked under bonett and from what I had been told to look out for everything seemed ok. Upon the journey home I'd got not even half hour back and red light popped up on the dash and temperature was in the red section so pulled over rang the bloke he said give me five let me ring my machanic, five minutes later I rang again and... Blocked my number.
Basically the engine gets really hot very fast, coolent seems to vanish but when I take the cap off it comes flooding back into the header tank. As I speed up the temp gauge goes down as I come to a stop in traffic or slow down it shoots back up and the light comes on. Iv squeezed a few of the pipes to and from the header tank everything seems to be flowing ok, everything is tight on so I assume there's no leaks as I can't see anything underneath when left stood so now I'm stuck. Can't go anywhere in the car apart from 5 minutes up the rosd. Iv had it looked at by 4 different garages and no body can get to the bottom of it? so far had a new pipe fitted because it's was loose and a new water pump and one said it was the dreaded head gasket the other 3 say no it isn't the head gasket, the garage that did my water pump eliminated her cooler by blanking it, no white stuff under cap that seems to be ok so Now I just don't know what to do and this forum seems to be pretty helpful so anyone who can shed some light on it that would be great!
