Feb 04 2017, 9:59pm. I have done 7 water pumps on my 6 liter and these are the simplest engines ever made to not airlock. 5.3 Engine Fuel Injector Failure The fuel injectors in a Chevy 5.3 Ecotec3 engine spray fuel at about 1500 PSI pressure. This can be easily remedied with a Melling performance pump. We made 900 HP With a ProCharger on a 427-inch LS Engine. Right. This sensor is also the one that operates the dashboard coolant temperature gauge, and … .. If the climbing temperature is not dampened or dissipated, the engine will overheat and stop working. Start the engine and listen for any unusual noises. Gen III PCMs are powerful control modules but they are of little use without tuning software to change engine (and transmission) operating parameters. If the temperature is too high the engine will fail in short order. Boil-over won’t occur until about 265F … Free reving (or worse - racing) on an engine that has not fully reached it's oil operating temperature is extremely dangerous. 300,000+ Mile Engines. Home; About ; KODIAK CHEVROLET 6.2 LITER V8 (LS3) FRESH WATER COOLED MARINE ENGINE – 400HP – 3 Year Warranty – EPA CARB Certified – With CAT. Normally it runs at 210 or below. The engine run time is greater … Took me first time out to overheat the engine (idiot temperature light did not come on) and I have had to reolace the head. 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. Tech Note: Always make sure your oil is at operating temperature before running your engine hard! The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). Fits GM Gen III & IV LS Engines LS1-2-3-6-7-9-LQ4-LQ9-4.8L-5.3L-6.0L-6.2L & More! Re: engine running cold. Engine starting is also more consistent in all operating conditions. The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. Conditions for Running the DTC. If no unusual noises are noted, run the engine at approximately 1000 RPM until normal operating temperature is reached. A bypass valve or a bypass hose permits coolant circulation through the engine when the thermostat is closed. Return to top. Conversely, stock LS oil pumps do tend to lose efficiency at engine speeds exceeding 6,200 to 6,500 rpm. It will show running ~210 all the time, right? Because I am an engineer and need to look at guages, I had the mechanic install a temperature guage with the sensor at the back of the block near the seat and guages. FEATURES. If you want to go with a large bore — larger than 4.060 inches — then an aftermarket LS block is in your future. 50 Report; Crall54 answered about a year ago My captiva overheats when is idling but if you are drive it is normal Operating temperature. Car engines run remarkably well using combustion fuels and oil for part lubrication. Lexus LS 2002, Premium Engine Coolant Thermostat by Stant®. Active 5 years, 10 months ago. Properly maintained 911 engines can last over 300,000 miles when oil temperature is kept in the optimal 180°-210°F range. They're also subject to being clogged or losing pressure. Two Minute Tech : Engine Episodes Reduce Coolant Operating Temperatures Behind the Scenes: Edelbrock's LS Supercharger, Part 1 Behind the Scenes: Edelbrock's LS Supercharger, Part 2 Repower a Chevy SS 454 With Heads, Cam & EFI Part 1 Repower a Chevy SS 454 With Heads, Cam & EFI Part 2 Swap an LS into a 5th Gen Monte Carlo Install A Trick … Also use a quality oil filter! If the engine is too cold, fuel doesn’t vaporize as easily, leading to poor performance and increased fuel consumption. When possible, you should always allow the engine to warm up prior to driving. If the engine is too hot, fuel may combust on compression instead of spark, detonation, which can cause severe engine damage. Advantages: • Robust industrial design with a small footprint and ultra-quiet operation. Engine life vs. Oil Temperature. Oil temperature is probably the most important thing to know, specifically for those of us who are pushing our cars hard. 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.
