Question Engine operating temperature?

Quick question - (98 C230)

it's starting to warm up a bit (10-15c (50-60f)) and I've noticed my engine temperature gauge rising above the midway point (80c), sometimes reaching midway to the next line (approx 90c) - It does go back to 80c when I start driving & reach an open stretch. My engine temperature constantly stayed at 80c during the winter (-10 to -25c).

Is that "normal" for the temperature gauge to actually move or should I be concerned - My previous BMW's engine temp (which was a nightmare in terms of cooling issues ) stayed in the middle unless something was wrong.

Also - when should the auxiliary fan (the fan behind the radiator?) kick in? I've kind of checked to see if it was on a few times (with ac on or off) and it was never running...?

Thanks in advance everyone!

**edit**
fan behind the radiator is running..

well most of the time my temperature stays between the 80 and the next mark which if i remember right is 100. the aux fans will kick on at 100C or a certain pressure. if your temperature rises while sitting in traffic for a long time, then i would say its normal. if it rises to 100 at any other time then i would maybe start looking for whats wrong.

Post Which Fan behind the radiator?

Are you saying that the mechanical (Viscus Clutch Fan) is not spinning when the motor is running? When the A/C is on, Engine Hot, ALL the Fans (Electric in front of the radiator) AND the Viscus Clutch fan behind the Rad. should at least be spinning if not spinning hard. If you turn on the A/C and the compressor is running I believe the electric fans should be running too. There is a relay and a temp control switch in charge of turning these on. Check your fuse box to start.

Most of the 4 cylinder cars in this section usually run pretty stable in temp under most conditions at just over 80c.

Good Luck!

Question What's the deal?

I sure would like someone that really knows to explain why some cars (My C-220) stays ROCK SOLID right above 80c in all but the most extreme conditions, while others fluctuate like 00_230_K and t-im just described.

All the cars and pick-ups I have owned over the years have remained stable with regards to Thermostat opening temp. unless in extreme heat or something was going wrong.

Good Luck!

If it helps to find an average, my car is a '99 c230K and it stays locked in at 80 unless it's stuck in stop and go traffic on a very hot day but even then it barely budges above.

Mine stays at 87 Celsius all the time aswell, but it used to fluctuate before I changed the Thermostat, now its rock solid at 87 Celsius. Make sure yours has been changed, it should be changed when you flush the coolant every 2-3 years.

All of my Merc's stay between 80° and 100° (just below the 100° actually)... this is completely normal... the reason you notice the fluctuation is that Mercedes gives "actual" readings, unlike most cars (like my old Honda) that would stay rock steady just below mid point unless there was a problem, then it would move... car makers do this so people don't panic if their temp needle moves... BMW's stay rock steady in the center unless there is a problem.

But yes, have your coolant flushed if it hasn't been done in ~2 years... I am actually making my appt right now for coolant flush and transmission service.
