It turns out that coolant (usually a 50/50 mixture of coolant and water) has some fantastic properties that are ideal for use in engines. A coolant mixture of 50% water and 50% ethylene glycol has a boiling point of 223 degrees. What do you think? 95 camaro coolant temp sensor, Sometimes for days at a time, then it acts up and stalls. The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations. This is used as a base setting (or startpoint) for the adaptive idle routines and also the base IAC position when the vehicle is moving. From there, it goes back to the radiator to be … Provides an easy and economical way to measure fluid temperature and convert to a universal 0-5V output. When the A/C is on and the coolant temperature reaches 85°C (185°F), the low speed cooling fan will be turned on at vehicle speeds less than 56 kPh (35 mph). Audi engines use a mix of antifreeze and water to cool the engine while it is running. The tip of the sensor is submerged in coolant. However, it takes much longer for oil to come up to temperature than coolant. You can use a low temp as a "band-aid" at the track sometimes. Keep in mind that many (ECT) sensor problems are more often due to; wiring faults and loose or corroded connectors than failure of the sensor itself. 15. The infrared thermometer aimed at the water temp sending unit shows 165 to 185 which I believe is normal. Should I put my coolant temperature sending unit in the head or in the intake manifold next to the thermostat housing/coolant outlet? If you want to run the engine cooler, change the thermostat and reprogram the thermo fans to come on earlier. Greg Fast (yes, the last name is spelled correctly) 1970 Camaro RS Clone 1984 el Camino 1973 MGB vintage E/Prod race car As a general rule of thumb, after the car is warmed up, oil tends to be a few degrees warmer than the coolant (usually 10-15 degrees Fahrenheit). The old gauge will be trashed and replaced soon. Thanks, NYH1! Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. ULTM8Z Veteran Member. If you want to keep the engine nice and cool under high load, an engine oil cooler is ideal. In stop-and-go traffic and heavy acceleration, however, oil temperature usually gets much higher than coolant temperature. The cooling fans are controlled by the PCM. Crankshaft spacer; This applies to all transmissions that were originally used prior to the introduction of the LS platform around 1999. IDEAL (Rich) (Lean) Base (ltrims) - 0 + (Lean) ... Change all points in the Closed Loop Enable Coolant Temp vs IAT table back to stock (re-enables closed loop operation and fuel trim leaning) 12: Change all points in the Power Enrich Fuel Multiplier vs. RPM table back to stock (re-enables PE mode) ... LS1 … But the temperature is usually around 1500 degree Celsius. The hole is an unusual size for a gauge sender, so an adapter sleeve is first screwed in, with the sender then screwed into the sleeve. peterbilt coolant temp sensor, Step 1 - Locate Coolant Temperature Sensor. It seem to be about ideal for an LS motor. With a properly pressurized cooling system, coolant will not freeze until –30°F, and it won’t boil until +270°F (new oils don’t start to break down until well over 270°F). The temperature inside the combustion chamber is always transient and depends upon various parameters like cooling system, load on the engine, combustion chamber shape and the like. your coolant temp range is normal,(not ideal, but normal for a stock 1985 corvette) engine oil needs to reach and stay at about 215F-240f to lube and clean correctly and burn off moisture trans fluid I try to keep under 160F,surely below 180F , It is turned off if the coolant temperature lowers to 108°C (226°F). This assumes a person is running a 50/50 mix of antifreeze and water. The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. This sensor is a thremister, and has a sensing bulb that has to be submerged in coolant. The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. Coolant travels through the hoses, and is needed to keep many of your vehicle’s systems operating smoothly. The ideal temperature for an automatic transmission is around 175 degrees. Today they came on at the start of the vehicle with coolant in the 170-175 range (this makes me think coolant temp sensor is out of whack). You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. Apr 18, 2010 #2. Pull the latch for the hood and open it, making sure it is secure before letting go. The coolant temperature sensor, abbreviated as CTS, in your car is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason. Engine Coolant Temperature (ECT) Sensor Testing Made Easy. The temp gauge reads backwards, right to left, which I believe is an indication it is busted. Once you're out on the track for half a lap or so, your coolant temps are going to be in the 200 range anyway so the thermostat is fully open regardless. Cars often have the coolant for the engine as a heat exchanger for the transmission fluid and therefore, they will often hold the same temperature if you are driving it normally. If an air pocket forms due to a leak or due to a pressure … “crank spacer” is a bit of a misnomer. So your th350, th400, 700r, early 4l60e, early 4l80e, etc, will need to have one of these crank spacers.
