Engine temperatures
Engine temperatures
From what I understand, the OM606 NA is supposed to run at 85ºC, as it comes with an 85ºC thermostat, and the OM606 turbo should run at 80ºC, having an 80ºC thermostat.
In a real world setting however, most people see a coolant temperature between 80 and 100ºC, and my question is hence if anyone has ever determined what exactly is optimal?
Apparently, there is some small improvement in MPG with increased temperature, but at what temperature would increased engine wear start to occur?
The question is relevant, because if the typical usage by one person causes their engine to run typically, say, 90ºC, then things can be done to decrease this temperature. i.e. through a different thermostat, or changes to the oil cooler system.
Or if a person's engine runs typically 80ºC with typical usage, reverse changes could be made if 90ºC is felt more optimal, i.e. with a higher temperature thermostat, etc.
As an add-on question though, can someone also explain the difference between coolant temperature and oil temperature?
From my understanding, the stock oil cooler for the OM606 starts to open at 110ºC and is full open at 125ºC. But isn't coolant temperature supposed to approximate oil temperature to within a few degrees?
By this logic, the engine hence shouldn't be getting so warm that the oil temperature is ever up in the 110ºC range!
Thanks!
Ok, so this thread is to discuss engine temperatures for the OM606, and see if some clarification can be obtained!
