God's Chariot. The E30 was produced primarily from 1982 through 1991. The cabriolet was the one exception which was produced through 1993.

82 C is minimum I would start thrashing the motor, as the Oil also needs to warm up
88 C is good
120 C is overheating

Mein Auto:
Thank you nick! I've installed an after market water temperature gauge because the meter in the cluster seem to have failed on me. The temperature in the gauge reads 84 - 94 during mid day and 80 - 92.
Are the numbers ok or do i need to do something about it?

Your Water temperature readings are 100 %
Some later ECU's got more fussy about water and air temperature, but not ours
Engines are generally happy with the temperature being between 75 to 115 C at the sleeves with correspondingly higher temperatures around the combustion dome.
