How many volts does a radiator fan need?
Normal voltage for a radiator fan is around 12 volts. If the volt meter reads 12 volts, the problem is not the power and the fan needs to be replaced.
At what temperature does the radiator fan turn on?
about 200 degrees Fahrenheit
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
Why does coolant level drop on Avalon XL?
I noticed on my 2000 Avalon XL that the coolant level in the overflow reservoir drops a couple inches every year. I understand that temperature affects the level reading; however, I usually check first thing in the morning and compare the readings in similar ambient conditions (i.e., similar weather conditions, etc.).
Where is the relay on a radiator fan?
The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.
When does the engine cooling fan come on and off?
The fan will then cycle on and off as needed to maintain the proper coolant temperature. So, The fan runs mostly at idle or low speed when the engine is at normal temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees.
Can a electric fan be used on a radiator?
If your Avalon uses an electric fan to move air through the A/C condensor/radiator assembly then the fan motor itself might be suspect or even the thermostatic switch that turns the fan on as the coolant temperature level begins to rise. You can also reduce the heat load on the radiator by running the A/C in the most, more efficient mode.
