Question about 360 Cooling Fans

Answers: 1) yes and 2)yes

 

Both cooling fans are controlled by a twin contact switch (number 9 in drawing) which is situated in the right-hand radiator.

Isn't the left one for WATER and the right radiator for OIL as in the 355? I could not hear my right one and went to my mechanic who said it was running slow and eventually would fail and the car would overheat. Since the replacement I can HEAR it now!!! Car also runs slightly cooler.

 

I have the 2004 360. firts thing i did when i got it was ground the thermo switch by taking the plug conector off the thermo switch and jumping the green and the black wire.this makes both fans turn on. both fans stay on when i open the switch and the car stays cool between 180f and 208f.turn the ignition off and both turn off.if i turn the ac on the passengers blows stronger. I just by pass the stupid thermo switch.and dont have to worry about over heating and the drivers side fan turning on.
They both come on with the ignition is open and i can here them on.no more over heating in stop and go traffic in miami fl.

 

Yeah... don't do this.

 

Can you give me a brief explanation why not?

 

The fan isn't designed, nor meant, to activate below a particular coolant temperature. This is due to the desire for the engine to come up to running temperature as quickly as possible, as well as stay within the safe temperature margins. (Sometimes I get the feeling that some drivers think the colder the fluid, the better... ie, they'd buy some mod that would keep the coolant at 70F if they could.)

Having the cooling fan active ALL the time simply makes the engine take longer to come up to operating temperature, which is not a good thing. If a fan isn't working due to a sensor, electrical, or other issue, the proper thing to do is R&R the defective part of the system... not hot-wire it together like some hackjob.

 

never said my car had a problem ,just want my car to run cooler at a stand still for pro long periods with no air flow..gee I thought until the thermostat opens your car is cold any way. so what your saying is when your driving in cold 45 degree weather the car is always going to be cold and will never get warm so its bad to drive in cold weather because the engine will take to long to get warm.. doesn't make sense.

 

No, that's not what I said.

 

You want the engine to run at a constant temperature, wide temp variations while running aren't good for an engine. The fans are designed to keep the engine within an operating range. They come on at one temperature and go off at another, the variance in most cars between the temp they turn on and the temp they turn off isn't dramatic.

If you had to run the funs all the time you would fall below this and in essence the engine would run inefficiently.

 

Mine stopped working, which I noticed when the car got hot in stop-and-go driving, and it was the relays that were bad.

 

Engine thermostat controls the temperature of the engine not the radiators. If the engine is cold the thermostat stays closed. It will creep open as it warms up. If the engine temperature drops due to too much cold fluid entering the engine, the thermostat will close slightly to restrict/regulate the flow.
Running the fans constantly will only reduce their life and burn a little more fuel from the extra electrical load on the alternator.

 

I dint like the high fluctions of the needle hitting close to 210.
After new thermostat and my fans running direct in this 100 degree wheather in miami and stuck in stop and go traffic with ac on for an hour needle dosent budge past 185 just stays at the quarter mark just slightly past.but always at the quarter mark.car is not driven every day maybe once a month.so the fans are only on for an hour .so iam. Not worried about life span.even my engine bay stays so much cooler. No more open the hatch to let out the heat.stays super cool.what a diffrence.

It is desirable for the oil to get hot enough in order to evaporate any condensation in the oil.
Modern synthetic oil is safe to operate at elevated temperatures

 

At 180-185 and 1 hr drives iam sure the engine and oil is warm enough to dispel the condensation out that pvc valve.
