If the coolant could not circulate, hot spots could develop inside the engine. Engine's Normal Operating Temperature. Get fast engine warm-up and dependable engine operating temperature with a Stant thermostat. The one that suited our needs was Dart’s SHP LS Next Pro iron block. If the engine is too cold, fuel doesn’t vaporize as easily, leading to poor performance and increased fuel consumption. Right. Since the amount of thermostat opening is depended upon engine temperature, the exact operating temperature of the engine can be precisely controlled. Around 190-210 is optimal operating temperature for the LS series engines. Lincoln LS 3.9L 2004, Engine Coolant Thermostat and Housing Assembly by Stant®. (2003 thermo is different fix, knockout center element and use thermo big spring to keep bypass hole closed) Reduce Coolant Operating Temperatures . They're also subject to being clogged or losing pressure. Pouring The Foundation. As engine oil operating temperature increases, the viscosity must also increase in order to provide an adequate oil film clearance to prevent metal-to-metal contact. • Temperature monitoring for protection of the LED light engine . Return to top. If the engine is too hot, fuel may combust on compression instead of spark, detonation, which can cause severe engine damage.

As a result, engine … Free reving (or worse - racing) on an engine that has not fully reached it's oil operating temperature is extremely dangerous. Temperature: 183F. Conversely, stock LS oil pumps do tend to lose efficiency at engine speeds exceeding 6,200 to 6,500 rpm. Boil-over won’t occur until about 265F … 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. Either that or every single tstat you put in sticks closed. This can be traced to several different factors, most of which contribute to pump cavitation. Took me first time out to overheat the engine (idiot temperature light did not come on) and I have had to reolace the head. Because of that pressure and the high temperatures, they are under they can wear down faster than you might expect. Also use a quality oil filter! Before getting too far into a discussion of electric fans and PCM calibrations, it is important to first consider air conditioning control.
