Advantages: • Robust industrial design with a small footprint and ultra-quiet operation. Oil Temperature and Engine Life. I have done 7 water pumps on my 6 liter and these are the simplest engines ever made to not airlock. The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. When the PCM senses a signal voltage lower than the normal operating range of the sensor, this DTC sets. Active 5 years, 10 months ago. Car runs cool, only takes extra 2 minutes for heater to get warm. This sensor informs the PCM whether or not the engine has reached or exceeded the operating temperature value. A bypass valve or a bypass hose permits coolant circulation through the engine when the thermostat is closed. If no unusual noises are noted, run the engine at approximately 1000 RPM until normal operating temperature is reached. It is a good practice to allow the oil sump and water As a result, engine … LS Marine Engines Menu. Pouring The Foundation. Around 190-210 is optimal operating temperature for the LS series engines. The concern is that this higher temperature will create a slightly thinner oil film and the components may touch, causing what is called mixed film lubrication. However the range for your thermostat depends on the type of your engine, load requirements, weather, and other variables. This can be traced to several different factors, most of which contribute to pump cavitation. Because of that pressure and the high temperatures, they are under they can wear down faster than you might expect. March 17, 2016 by westcoastoffshoremarineparts | Leave a comment. Saw the temperature creeping up towards 260, but never getting there. Free reving (or worse - racing) on an engine that has not fully reached it's oil operating temperature is extremely dangerous. Sitting in traffic, I watched it go from 210 up pretty quickly to the third tick mark, which is when I cranked the heat and it stayed at the third tick, then went back down to 210. I read in the Motor Oil University article on Bob the Oil Guy's websites that: The automotive designers usually call for their engines to run at 212°F ( 100°C ) oil and water temperature with an oil thickness of 10. We were provided an independent, controlled dyno test conducted on a Chevy LS engine to quantify the temperature reduction by comparing cylinder-head operating temperatures using Stay Frosty Race-Ready, waterless coolant, and the standard 50/50 mix of antifreeze and water.
