engine cooling fan should not do this - bad temp sensor likely
== == Cooling fans are designed to start at 235 degrees
mine kick on around 230 temp.
water contracts when cooling until about 4 deg. C. From that temp. further cooling causes the water to expand. as it freezes it continues to expand, that is why ice floats.
in the thermostat housing on the left side of the engine
they do for the ac they only come on when the engine temp is peaked about 210 deg
it's the cable that connects your heating/cooling temp slide switch to the heater box inside the engine. If it's broken you will have no temp control.
it usually turns on around 200 degrees
Clean your radiator with Simple Green or something that gets rid of grease, make sure it doesn't eat aluminum though. Your fan may be working but no air is getting through your radiator.
There is not a separate cooling fan sensor, it controlled by the ECM which get it's reading from the ECT (engine coolant temp sensor)
almost all cooling fans run temp to help get engine warm up very quickly and may turn going the road on cold days to keep temp up in the engine
Your cooling fans may be coming on or you might have a low temp thermostat. Either way, a cool engine is better than a hot engine.
That indicates the engine temp is running to low: the computer should give a check engine light and often the temp gauge will not work either. you need to replace the thermostat
On the 2.4L z24 I think you are talking about the one on top on the driver sid. That is the OUTLET GASKET and it is a rubber O RING.The temp. sensor is screwed into that to detect cooling temp. as it leaves the engine. Coolant leaves the engine to head to the radiator to be cooled.
The cooling fan comes on when the engine reaches a certain temperature and is controlled by a sensor switch that kicks the fan on when the temperature reaches the preset temp.
Range is the difference of cooling water inlet and cooling water outlet temp
If your engine light comes on and your temp gauge is lower then normal. listen for cooling fans. if they are also running chances are you need a new thermostat
The coolant temp sensor for a 2003 Passat 1. 8L is located on top of the engine, near the upper radiator hose. It constantly monitors the engine's temperature and adjusts the cooling fan as needed.
Yes it is normal if you have an electric fan. The fan will run until the engine temp lowers to normal.
Either bad ground on your gauge or your electric cooling fans are going bad.
May be air in your cooling system. Unless you have a vacuum to put coolant in, it is very hard to get all the air out. It will cause your engine to heat up quickly and your temp gauge to be very erratic. If water is missing steam will cause that.
there can be up to 3 temp sensors on an engine. One for the dash guage, the second for the computer input and the third controls the electric cooling fan. If the obd system called a bad temp sensor, then it is the ECT SENSOR FOR THE COMPUTER.
I believe it turns on and off the fan (1 out of 2) that cools the engine according to the temperature it's at. If it doesn't work the engine may not know to turn the fan on and the engine could overheat. Here's a tip. When you turn on your A/C or Heater, both fans come on. The A/C cooling fan and the Engine Cooling fan.
it senses the engine temperature and sends a signal to turn on the radiater cooling fans, and it also sends info to guage in car to tell temp, of engine.
Check your cooling fan
