When do the thermo fans come on in a Ford Falcon?
If I leave my car running on the drive way even on a low 20s day with the bonnet up, the thermo fans will kick in after a few mins. They are usually sensitive – ie not wait until the car is very hot. Usually they will also come on 100% of the time at a low speed when the A/C compressor kicks in. No.78379 writes…
What should the temperature of an engine cooling fan be?
Engine cooling fans may engage at one speed or multiple speeds and may kick on anywhere between 180 and 220 degrees.
Why do I Hear my thermos running in my car?
If engine driven then the fluid coupling may be buggered (or fan belt slipping a bit). If thermos, then maybe they are unplugged or the temp sensor for these are unplugged. You should hear them running when you pull up when its hot. Jump out and open the bonnet next time it heats up and have a look. notevenevelyn writes…
What happens to coolant in a closed loop cooling system?
A common misconception is that if coolant flows too quickly through the system, that it will not have time to cool properly. However the cooling system is a closed loop, so if you are keeping the coolant in the radiator longer to allow it to cool, you are also allowing it to stay in the engine longer, which increases coolant temperatures.
What are the low and high settings for thermo fan?
Low on at 85 and off at 80. Not sure what the high settings are as it doesn’t exceed 85 once the low fan speed cuts in. In your case you could go a dedicated adjustable fan controller which would allow you to adjust temps accordingly. http://www.spal-usa.com/fans/automated/accessories/fanpwm.html
What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
Why is my Mk1 radiator fan not coming on?
There are no air locks and I’ve bled the system in the usual way and the coolant is new and the correct mix. So, in traffic the other day I was sat for a while, hot weather and the temp gauge nearly went up to the red, still no fan coming on – at what point should the fan come on compared to the gauge reading, assuming the gauge is accurate (ish)?
Why are my cooling fans running at all times?
3. Cooling fans stay on at all times. If the cooling fans are staying on at all times, this is another (less common) symptom of a possible problem with the cooling fan relay. If the relay shorts internally, it may cause power to be permanently switched on, which will cause the fans to run at all times.
