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). 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). 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 … head temp. If you want to keep the engine nice and cool under high load, an engine oil cooler is ideal. 15. You can use a low temp as a "band-aid" at the track sometimes. Pull the latch for the hood and open it, making sure it is secure before letting go. Perhaps I'm overthinking the difference between rad. Therefore, A visual inspection of the (ECT) sensor will sometimes reveal a problem. Coolant hoses connect parts of the vehicle's cooling system together, such as the engine water outlet, radiator, water pump, and heater core. Apr 18, 2010 #2. Thanks, NYH1! In stop-and-go traffic and heavy acceleration, however, oil temperature usually gets much higher than coolant temperature. Under steady state cruising, where a constant supply of air is moving through the radiator and oil cooler, oil temps generally mirror coolant temps. 16. Provides an easy and economical way to measure fluid temperature and convert to a universal 0-5V output. A system with 15 psi cap will add 45 degrees for a final boiling point of 268 degrees. But don't think that the coolant gauge will tell you this information - it won't. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations. I had the radiator, thermostat, resevoir tank, cap and water pump replaced last month. 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 , The ideal temperature for an automatic transmission is around 175 degrees. Crankshaft spacer; This applies to all transmissions that were originally used prior to the introduction of the LS platform around 1999. The coolant temperature sensor is located on the engine block under the hood. The infrared thermometer aimed at the water temp sending unit shows 165 to 185 which I believe is normal. The tip of the sensor is submerged in coolant. 95 camaro coolant temp sensor, Sometimes for days at a time, then it acts up and stalls. Profile Page. This sensor is a thremister, and has a sensing bulb that has to be submerged in coolant. however, I want to get the correct reading. A coolant mixture of 50% water and 50% ethylene glycol has a boiling point of 223 degrees. But the temperature is usually around 1500 degree Celsius. ... With a pressurized cooling system and coolant,your boiling temp should be about 250 degrees. 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. The high speed cooling fan is commanded on when the coolant temperature reaches 113°C (235°F). IDEAL (Rich) (Lean) Base (ltrims) - 0 + (Lean) ...

LS1 … The real purpose of pressurizing is to give drivers a higher operating zone in case of extreme conditions. The thermostat OPENS at 195F degrees; but, the temperature continues to rise to the normal operating temperature. It would be easier for me to put it in the intake manifold. 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. The coolant hose connector provides a … Should I put my coolant temperature sending unit in the head or in the intake manifold next to the thermostat housing/coolant outlet? 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. The Wiring Specialties Pro-Series LS1 wiring harness is a Brand New, Tucked, Plug and Play harness that was designed and tested by our in-house experts specifically for a LS1 swapped Silvia S13. 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. 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. Coolant travels through the hoses, and is needed to keep many of your vehicle’s systems operating smoothly. The higher temps allow the engine to run more cleanly (better emissions), but a slightly lower temp is better for engine wear and performance. It was modelled on the actual LS1 engine and is race proven at Formula Drift. The old gauge will be trashed and replaced soon. 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). 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. 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. 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. From there, it goes back to the radiator to be … mine was running at 97 . Too Hot. It can collect contaminants including oil and corrosion that mix with the coolant and make it less effective in keeping your … The cooling fans are controlled by the PCM. Jun 16, 2010 #2 HoldenOnn Roll Cage Territory. None of us want that. SHARE POST #1. So your th350, th400, 700r, early 4l60e, early 4l80e, etc, will need to have one of these crank spacers. You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. Without a gauge, trying to figure out oil temp is just a guessing game. 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.

Coolant with a 50/50 mix of water and ethylene alcohol (anti-freeze) can function at temperatuares as cold as negative 36 degrees Fahrenheit. The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. The normal operating temperature of the coolant in an engine is about 210F to 240F degrees. Messages: Our Pro-Series is ideal for those looking for the best aesthetics, weight savings and reliability. 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. The PCM uses the coolant sensor to indicate operating temp. Engine Coolant Temperature (ECT) Sensor Testing Made Easy. Somewhat of the same problem here. “crank spacer” is a bit of a misnomer. The temp gauge reads backwards, right to left, which I believe is an indication it is busted. $44.99. Audi engines use a mix of antifreeze and water to cool the engine while it is running. 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). It is turned off if the coolant temperature lowers to 108°C (226°F). The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). It seem to be about ideal for an LS motor. 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. Over time the coolant in your engine can break down. On a C5 motor with a stock engine management computer (ECU/PCM), elevated coolant temps cause the PCM to retard timing, which reduces horsepower. Coolant travels through the block, up in to the cylinder heads, and out of the engine at the thermostat housing. Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. Brian flynbrian48, Nov 14, 2012.
