To repeat what I put in post #85 earlier this week:@ Maverick
not questioning what you wrote and you probably speak from experience, but are you saying that when our temp gauge shows ~90ish and sticks there, that the temperature actually can vary +- 10 degrees or so ?
Would it not move, even by some tiny bit to indicate the temperature change ?
Why does it gradually build up when you start a cold car, but then stick to the 90ish mark ?
Though I do find it really strange that it shows the same working temperature winters/summers/traffic jams/highways.
"The temp gauge on modern cars is little better than a warning light. If you have an engine problem it will jump from normal to danger in a split second. Its been said above, when was the last time you saw your gauge move when you were sat in traffic. The fan might be running but the gauge still says its normal and fans don't come on until the temp hits about 110 degrees.
Try it with a IR temp sensor or a simple thermocouple if you don't believe it."
Maverick is saying exactly the same thing.
On many forums owners complain about the lack of a temperature gauge, our other car does not have one. Since the modern gauge is designed to work in 3 positions i.e. cold, normal and panic the warning light is just as good.
