the engine had been operating around 90C, hitting 100C in stop and go, but aided by a "cool harness" (resistor mod) it drops down to 90-95C. in severe traffic temps are in 95-100C range. without the help of the cool harness the fluctuations would be more severe. i have 40% MB coolant mix and have replaced the thermostat. although some say that this is within normal range i suspect partial clogging as i have seen other cars operate at much cooler temps.

the readings i mention were taken using a laser sighted non contact infrared thermometer. it literally takes the surface temperature where the red dot is aimed. i took readings down and across the radiator as some have suggested and was not really that surprised at what i found. just wanted to get some verification.
