I always monitor for hot chicks on the roads rather than the engine temperature on my display.... but this is just me I guess.I strongly suggest you change from monitoring your engine temperature to monitoring your body temperature. My 1984 300D Turbo, with recent radiator, thermostat, coolant flush, fan clutch, temp sender, etc etc stays at 85-90C almost ALL the time. Safe would be around 190F, 90 C. Commonly a water cooled engine may run at 220F, 105C maybe even 230F, 110C in the summer with the AC on without significant problems. the road tax is a killer though, even more than the LP. irks me just to look at it. as long as the engine does not catch fire, it is all system go for me. It started up, then lost power, again. Do not exceed 100 degrees CSo what happens if water temp exceeds operating limit? currently using the E250 coupe as a daily but i have had a soft spot for AMG cars for the longest time and thinking if i should jump right in. cheers mate, thanks for your input.I think an S class is more comfortable... but what you want is a car with both "wild" and "submissive" sides. It feels so Porsche-like and yet has much more glam factor.Yes, AMG is a car you need to try at least once in your life. i think it's the single most important thing for a daily driver. It all get fixed in 01/04. Any W123 diesel with the cooling system operating at full capacity should be the same way, IMO.
the road tax is a killer though, even more than the LP.
that's almost a submariner there.. any regrets for AMG owners?
My cars thermostat is stuck open! irks me just to look at it. Catastrophic engine failure is possible.Both are serious matters. the road tax is but one part of the consideration. I must need a new thermostat. Your temperature gauge appears to display actual temperature, other cars do not. The water pump and coolant are the only newer components in my cooling system. Also, in comparing your temperature readings to other folks, please keep in mind that the old MB temperature gauges are not exactly scientific instruments.
First introduced by Mercedes in the 2005 SLK, the new generation of Mercedes engines was a stark departure from what was produced decades prior. While this can vary, in the E320 and C240, for example, the thermostat opens up at 87-degree Celsius. putting it in perspective, that's more than the bentley, lambo, and ferrari, but still i'd go for it. The ideal temperature for an automatic transmission is around 175 degrees. Mine is a SLK. how do you guys manage it when it comes to the time to pay road tax? I read that the Navy did a test and found the optimum running temperature was about 300*F for Diesel engines. The service manual indicates the engines thermostat should begin to open at between 88 and 92 degrees Celsius, the normal operating temperature should be 90 to 95 C. The gauge does appear to be high but is normal. that's almost a submariner there.. yeah road tax for sure is among the highest, but sns said it well "you got to pay to play" (hilarious as it is so true in every sense)... but even my SLS can be a great daily driver... except unfortunately, I am too lazy to drive it every day.I've had my fair share of exotics and near-exotics... and I can safely say the SLS is my favorite so far, even better than the 458 and California imho. Hot coolant flows away from the engine and into the radiator to cool off.
