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 coolant temperature sensor is located on the engine block under the hood. The temperature of the coolant can rise above 212F degrees because coolant is pressurized (NOT because the water is mixed with antifreeze). SHARE POST #1. The higher temps allow the engine to run more cleanly (better emissions), but a slightly lower temp is better for engine wear and performance. 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). If you want to keep the engine nice and cool under high load, an engine oil cooler is ideal. Too Hot. 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.

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. 16. Audi engines use a mix of antifreeze and water to cool the engine while it is running. 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 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. You can use a low temp as a "band-aid" at the track sometimes. The cooling fans are controlled by the PCM. 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. mine was running at 97 . Provides an easy and economical way to measure fluid temperature and convert to a universal 0-5V output. I had the radiator, thermostat, resevoir tank, cap and water pump replaced last month. Should I put my coolant temperature sending unit in the head or in the intake manifold next to the thermostat housing/coolant outlet? The real purpose of pressurizing is to give drivers a higher operating zone in case of extreme conditions. 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. In stop-and-go traffic and heavy acceleration, however, oil temperature usually gets much higher than coolant temperature. From there, it goes back to the radiator to be … It would be easier for me to put it in the intake manifold. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations. 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. Under steady state cruising, where a constant supply of air is moving through the radiator and oil cooler, oil temps generally mirror coolant temps. This device works on the principle of dependence of potential difference in temperature. Somewhat of the same problem here. Joined: Sep 12, 2003 Posts: 42,180. 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. Messages: The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. Hit the star under this post if it was any help to you =D. The infrared thermometer aimed at the water temp sending unit shows 165 to 185 which I believe is normal. The temp gauge reads backwards, right to left, which I believe is an indication it is busted. But the temperature is usually around 1500 degree Celsius. Coolant travels through the hoses, and is needed to keep many of your vehicle’s systems operating smoothly. Pull the latch for the hood and open it, making sure it is secure before letting go. 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. 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. 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. 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. coolant temp and cyl. It can collect contaminants including oil and corrosion that mix with the coolant and make it less effective in keeping your … Therefore, A visual inspection of the (ECT) sensor will sometimes reveal a problem.

So your th350, th400, 700r, early 4l60e, early 4l80e, etc, will need to have one of these crank spacers. 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 … Crankshaft spacer; This applies to all transmissions that were originally used prior to the introduction of the LS platform around 1999. Brian flynbrian48, Nov 14, 2012. 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. What do you think? But don't think that the coolant gauge will tell you this information - it won't. 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. You will search for the sensor within the engine block itself, using a drop light if you need help to see it better. On a C5 motor with a stock engine management computer (ECU/PCM), elevated coolant temps cause the PCM to retard timing, which reduces horsepower. Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. Profile Page. 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.
