2000 Discovery II over heating AGAIN!!!
#11
Mr. Alan,
Without an OBDII scanner of some type, you would be depending on the Rover factory gauge. Note these two pictures, by different members. Different OBDII temps, yet factory gauge is "dead center" in both trucks. This "undocumented feature" or "bug" in the ECU program makes both owners see same display, while they are 38F apart.
If you don't have a better gauge, running while it does not show overheat may be a like SWMBO saying she can't be overdrawn because she has checks left. When testing, no need to sail past 195-205, you don't need to go to 227 to "prove" you are overheating. Running on the high edge just helps warp heads, make sleeves slip, cooks oil to worthless dribble.
IMHO most Rover owners are riding along in blissful ignorance, if they saw the real temps, being the men of action, repairs would have started long ago. No one wants to be a fool and drive a truck that is overheating. But Rover drivers are just fooled by the instruments.
