If you actually watch the logged temp vs the gauge, the 'normal' position covers a HUGE range of temperatures. A key place people go wrong with Subaru builds is setting the main clearance too loose. Engineered for high performance in a wide range of operating conditions, its advanced formula withstands rigorous and You would have to be careful what you are doing so as not to create hot spote in areas where wires/electronic equipment would be. ... as long as the engine temperature is not out of the range spec'd for it, ... the entire cooling system should achieve nearly the same temperature as the engine within a small difference if the operating temperature is achieved and it should do it within a short length of time. replaced fuse in engine - Answered by a verified Subaru Mechanic It seems to run at the mormal spot on the gauge when driving on rough roads or when the engine downshifts while going uphill. A coolant temperature sensor costs 30$ to 100$ and the labor costs 40$ to 150$. The result of this is a gauge which reads very near to the top of the scale when the engine is at normal operating temperature. Is that normal if your pushing the engine? It is full of fluid, belt is in good condition, no leaks. Since the block is alloy the clearance tends to grow as the engine comes up to operating temp. If the engine coolant temperature increases over the specified range, the indicator light/warning light blinks in RED. I love my Subaru Outback 2007 but recently its been having trouble starting in the morning either when it’s cold or the temperature has changed significantly overnight. The models with one sensor usually both use the engine control unit‘s temperature and the same sensor for the gauge. On the block two aluminum heads a… At this time the engine may be overheating. EJ20 engine has aluminum flat-four cylinder block, with cast-iron dry sleeves. (the normal position covers from around 165 to well over 200 IIRC) rkramer. Its cylinder block deck height is 201 mm. Normal engine operating temperature, °C (F) 90 (194) Cars: Subaru Legacy/Outback: Euro Category: Euro III: Predecessor engine: None, new design. Archived. My regular mechanic replaced the radiator after Subaru’s diagnosis. This 2-liter motor replaced 1.8 liter EA82. If the engine coolant temperature increases further, the indicator light/warning light illuminates RED continuously. The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. In 1989 Subaru Legacy introduced EJ20 engine which later became the basic for the whole brand. I recently moved to Louisiana so we’re not talking extreme cold, just cold for here. Have a 2009 Subaru Forester XT 5 speed manual. Heat from the internal combustion process is transferred from the engine to the coolant. It’s what makes a Subaru, a Subaru. It’s one of the reasons why 99% of Subaru Crosstrek vehicles sold … 8 years ago. 2011 Subaru 2.5i Sedan. The Catalytic Converter which is the main exhaust emissions control device also require a minimum temperature of 300 °C before it can operate efficiently. It was the first representative of the legendary EJ series. When I turn the interior heat (temperature) down, the engine temperature rises, then returns to the midpoint on the guage again. Question type: Maintenance & Repair Does anybody know the normal operating temp of the coolant for the EJ25 SOHC Phase II engine? April 24, 2019. Reasons Why a Subaru Tests More Accurately When Hot Use a thermometer to monitor engine temperature running temp should be 195-215°F. also possible oil temp is a better judge of engine health. Naturally a short distance from the block you could approach that temp (say 1/4 inch away.) Reply after new radiator sensor says car running hot - Subaru Outback - Subaru Outback Forums says: Radio not operating and no lighted temp numbers on the control for the cabin. Modern cars almost never overheat, and that's because the liquid engine cooling systems on modern cars is designed to keep the engine operating at a safe temperature no matter what the circumstances are outside. Now, even after replacing the radiator, it moves up to about 3/4, before returning to the mid-point. Subaru probably does this to keep customers from coming in every time the water temp gets above 200 degrees during normal driving. Page 1 Quick Guide Forester 2020 Love. Some cars have two temperature sensors, while other car models have one. 2008 tribeca. Now, ... dr hose adapter + gauge + extra coolant + mess = totally possible. Asked by Chris15961 Dec 03, 2008 at 04:13 PM about the 1996 Subaru Legacy 4 Dr L AWD Wagon. In fact the engine experiences the MOST wear from a cold start, even more than compared to driving at high rpms on track when it … A Subaru lasts because of its engineering. The car cranks and cranks but won’t turn over for several minutes. The early symptoms that occur are an external oil leak, external coolant leak at the left head gasket, and potential coolant leaks at the right side of the head gasket, though this is less common. Genuine Subaru Certified 0W-20 Synthetic Motor Oil is a high quality, API SN Resource Conserving engine oil, uniquely formulated to handle the low friction design of the Subaru non-turbocharged engine. If the operating temperature is too cold (or hot), the engine will experience accelerated wear. ("Engine Overheating" 9-12.) If the engine coolant temperature increases further, the indicator light/warning light illuminates in RED continuously. However, since it can be difficult to spot exhaust when a car is in an idle state, the engine needs to be revved up to its standard operating temperature while the test is being performed. Hope that helped! Your Subaru engine is kept at the correct operating temperature by liquid coolant pumped through internal galleries in the engine block and heads. SubaruPartsPros carries top-notch engine block heaters that are designed to be installed in select model-years of the Subaru BRZ, WRX, STI, Impreza, XV Crosstrek, and other models. Mind you this is still in the middle it's just a little higher then usual though. This keeps the engine operating within a predetermined temperature range. The highest it got today was around 200 degrees Fahrenheit. The engine is designed to operate within a temperature range. For most cars, the normal operating engine temperature is in a range of 195 to 220 degrees Fahrenheit, though most dashboard temperature gauges don’t show an exact temperature. The thermostat on your Subaru Forester helps control engine temperature by allowing coolant to circulate when the engine is hot, and reducing coolant circulation when the engine is cold. The average temp in the engine compartment could be maybe 25 degrees above outside temp. The SUBARU BOXER® engine’s horizontal design offers better balance than other engine types and creates less vibration, which can lead to less wear and tear. If you start out with a traditional clearance of 2 thou or thereabouts, you'll have excessive clearance at operating temp. My wife's 1997 Subaru legacy wagon, 2.5, auto, a/c shows that it is running hot. However, the … Uniquely formulated to handle the low-friction design of the SUBARU BOXER® non-turbocharged engine, 0W-20 is engineered for exceptional performance in a wide range of operating conditions, and its advanced formula withstands rigorous and prolonged engine operation without viscosity breakdown. I can post pics of how my adapter is installed if you want. However, the two sensors are not directly compatible. Does anybody know the normal operating temp for the EJ25 SOHC Phase II engine, just curious because I just peaked at around 200 degrees F. Or is it time to change the coolant? An engine block heater ensures that your engine will run after ignition by heating up the engine prior to start.
