W210 E220 Temperature gauge question

[hotbaws]

Hi All,

I've go a quick question about the temp gauge on my car which I noticed for the first time at the weekend went over the normal 80° mark.

I'd been driving for 30 miles at around 80'ish then hit some traffic so crawled along for a couple of miles and I spotted that the gauge was sitting above the 80°.

After the jam disappeared and I started driving again it did go back to the norm but I'm just curious as to why this should happen and more importantly should I be worried?

I did have something like this on my old 730i and it was to do with the Viscous Fan IIRC.

All comments welcome

Thanks
Gary

If you had been motoring at a fair pace and then hit traffic, it would be normal for the temp gauge to go up as the heat from the rad and engine lose the air intake, it soon comes back down and this is normal as the fans take the temp down again

Malcolm,

Many thanks for the prompt reply!

The temp didn't drop as I sat in the traffic (I don't recall the fan kicking in to cool the engine down while stationary) it only really dropped when I started moving again as I'd been doing at most 5mph while in the jam.

I've been watching the temp gauge like a Hawk since I noticed it on Thursday evening, to see if it happens again.

Thanks
Gary

I've been watching the temp gauge like a Hawk since I noticed it on Thursday evening, so I've releaved to hear it's normal.

Just relax Gary when you are driving the engine is taking care of itself regarding the cooling, due to the mass of the engine, when you suddenly change things it takes a few minutes to respond, it OK and normal

Hi

If you had the air-con on the car can run warmer too.
