running hot - help
TDi90:
cheers for all the replies... will keep everyone updated!
paradigm shift:
I've had this problem too.. glad I'm not alone!
110 with a disco 200tdi. Always used to run just below halfway, now runs around the top of the white and sometimes smells warm. Heater won't blow hot any more. Tried changing coolant, then thermostat, then swearing, then head gasket and nothing has succeeded. Engine pulls well and appears to run fine. The guy at my local specialist suggested I'd know if she was actually overheating as it'd run like a pig.
My thinking is I've either managed to get a big old airlock which has killed the temp sender and/or water pump or the temp problem and heater problem are unrelated and purely coincidental. When it first happened I was at a rather amusing nose-in-the-air angle :lol:
Will keep an eye on this thread gonna try the water pump next I think!
TDi90:
before you try all that try the guage... check the earth on the guage, and maybe get a new guage, thats what im trying next, after that if she still is hot, i might look into things like water pump etc... (water pump seems to be fine though :shock: )

what temp sender you using?
when i had the disco engine in mine it always read high,very high,my fans come on at 92'c & that would equate to the guage of the scale :lol:
paradigm shift:
She ran at the right place on the gauge for years, so if it is the gauge it's a recent issue.
Bottom rad hose is cold, as is most the rad, and the heater's not blowing hot. Methinks no circulation for some reason.
