New MB owner worried about Temp Gauge!

[Paul Day]

HI Ive had my 2001 CLK couple of weeks and worried the temp. gauge seems to fluctuate between 80 and jst below 100 constantly when driving at all speeds. more noticeable whilst in slow moving traffic. Is this normal for this model or do I have a cooling problem?

Its usual in hot weather for the gauge to rise in standing traffic. But, on the move, it should be constant. You may need a new thermostat.

I was thinking that. In fairness Ive just been down to Devon and back with no problem s and no actual overheating-I guess in this weather thats a fair test of the cooling!

Mine fluctuates a bit as well. Under heavy acceleration it goes a little higher but under no stress it drops a little almost instantly.
