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. You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. What do you think? The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. Therefore, A visual inspection of the (ECT) sensor will sometimes reveal a problem. 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. Apr 18, 2010 #2. You can use a low temp as a "band-aid" at the track sometimes. It can collect contaminants including oil and corrosion that mix with the coolant and make it less effective in keeping your … mine was running at 97 . Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. 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 keep the engine nice and cool under high load, an engine oil cooler is ideal. The cooling fans are controlled by the PCM. Our Pro-Series is ideal for those looking for the best aesthetics, weight savings and reliability. It was modelled on the actual LS1 engine and is race proven at Formula Drift. 15. Messages: 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. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations. head temp. 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. 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). 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. Too Hot. Joined: Sep 12, 2003 Posts: 42,180. Idle Air Flow vs. Coolant Temp vs. (Gear & P/N): This table is used to determine the base airflow (in g/sec) for the IAC/ETC control vs Engine coolant temperature. peterbilt coolant temp sensor, Step 1 - Locate Coolant Temperature Sensor. It seem to be about ideal for an LS motor. Coolant hoses connect parts of the vehicle's cooling system together, such as the engine water outlet, radiator, water pump, and heater core. The high speed cooling fan is commanded on when the coolant temperature reaches 113°C (235°F). It would be easier for me to put it in the intake manifold. Thanks, NYH1! Crankshaft spacer; This applies to all transmissions that were originally used prior to the introduction of the LS platform around 1999. 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). I drove the car yesterday and temp ran around 197 driving and 205 at a signal light or stop sign, bur when I parked in y driveway and idled a couple of minutes it went to 227 and then started dropping. This sensor is a thremister, and has a sensing bulb that has to be submerged in coolant. Designed around the widely available GM-style Intake Fluid Temperature Sensors, the FAST® Fluid Temp Sensor & Converter Kit is ideal when trying to measure engine oil, coolant, transmission, intercooler/heat exchanger fluids and rear differential temps. But don't think that the coolant gauge will tell you this information - it won't. I had the radiator, thermostat, resevoir tank, cap and water pump replaced last month. If you want to run the engine cooler, change the thermostat and reprogram the thermo fans to come on earlier.

For the new coolant temp sender, there’s a convenient bung at the front of the passenger-side cylinder head, but removing it can require a bit of oomph due to the use of thread sealant. By using this "Fan Trick" both fans turn on and remain on low-speed, keeping the coolant temperatures close to an ideal 194F while hot-lapping. This device works on the principle of dependence of potential difference in temperature. 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. 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 , If your ideal operating temperature is 176-180 I'd agree with setting your fan to turn on at 185, that way it kicks on whenever your coolant temperature starts to climb above that temp your fan … The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). 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. A coolant mixture of 50% water and 50% ethylene glycol has a boiling point of 223 degrees. The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. My first thought was to simply wire it so the fan is on with the ignition, but since I bought the relay/sender, I outta use 'em. Without a gauge, trying to figure out oil temp is just a guessing game. If an air pocket forms due to a leak or due to a pressure … Coolant travels through the block, up in to the cylinder heads, and out of the engine at the thermostat housing. Somewhat of the same problem here. I noticed that both fans came on while my scanner was hooked up, but thought I turned them on by mistake. The tip of the sensor is submerged in coolant. Incoming search terms: 350 Sbc Engine Tempurature,Average Running Temp 97 K1500,Normall Coolant Temperature Ram 1500 5 7l,What Temp Thermostat Hemi,What Temperature Is Normal On The Water Gauge For A Tahoe,Whats A Normal Running Temp For A 5 7 Hemi,Why Is My 5 7 Ls Car Motor Running Hot Brian flynbrian48, Nov 14, 2012.

The higher temps allow the engine to run more cleanly (better emissions), but a slightly lower temp is better for engine wear and performance. Provides an easy and economical way to measure fluid temperature and convert to a universal 0-5V output. However, it takes much longer for oil to come up to temperature than coolant. The Coolant Temperature Sensor's Function. In stop-and-go traffic and heavy acceleration, however, oil temperature usually gets much higher than coolant temperature. Perhaps I'm overthinking the difference between rad. Pull the latch for the hood and open it, making sure it is secure before letting go. ULTM8Z Veteran Member. The PCM uses the coolant sensor to indicate operating temp. Engine Coolant Temperature (ECT) Sensor Testing Made Easy. The real purpose of pressurizing is to give drivers a higher operating zone in case of extreme conditions. 16. The coolant hose connector provides a … Audi engines use a mix of antifreeze and water to cool the engine while it is running. 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 … Under steady state cruising, where a constant supply of air is moving through the radiator and oil cooler, oil temps generally mirror coolant temps. “crank spacer” is a bit of a misnomer. 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). whats the average temp of a ls1? The old gauge will be trashed and replaced soon. Coolant travels through the hoses, and is needed to keep many of your vehicle’s systems operating smoothly. 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). The ideal temperature for an automatic transmission is around 175 degrees. Coolant with a 50/50 mix of water and ethylene alcohol (anti-freeze) can function at temperatuares as cold as negative 36 degrees Fahrenheit. SHARE POST #1.
