Wrong.
Yes the fan cools mainly the radiator, but it also circulate air through the engine for more or less direct cooling.
The cooling system (including the radiator) is a pressurized system when working and the pressure is achieved with increased temperature. Constant cooling means the required pressure will be difficult to achieve.
If the radiator is very cool while the engine is very hot, imagine what will happen when the cool coolant from the radiator hits the very hot engine. Metals do not like rapid cooling (quenching).
Cool coolant on one side of the thermostat and very hot coolant on the other side means the thermostat will not work appropriately.
As the thermostat opens, cool coolant rushes into the engine, cooling it rapidly. Then the thermostat will close fast (due to the cool coolant) and the engine temperature will rise again. This cycle will keep raising and crashing the engine temperatre, confusing your ECU.
In all these, you will hardly achieve closed loop. Failure to get to closed loop means your ECU will continue dumping fuel in your engine, trying to warm up.
Lastly, your fan takes some energy to run. This energy is drawn from your alternator. Your alternator draws from the energy produced by the engine. This means that constantly running the fan is taking reasonable energy from your engine. This will stress your alternator and reduce its life span and also further increase fuel consumption.

You got the drill,

who wouldn't want to be an admin just like the same way being an admin made you a billionaire right?

I recently bought a used 07 accord and the fans were connected directly and i noticed it's idling high and it's consuming fuel, i used a scan tool to scan for codes, these are the codes

Please I need the contact of any good gear master at Oyingbo. And directions on how to get there from Marina or Costain. Thanks.

dalitigator:
My fan were connected directly. How do we fix this?

Good day house, honda civic alternator was faulty it's over 3 months now but i went to fix it early last month. while i was driving the car to the rewire shop with his battery i didn't notice the car was running without the fan on and the temperature didnt rise on the cluster board..I got to know after i parked the car and hood was open then i noticed some water leaked at the top of the radiator like a sign of overheat, to cut it short after fixing the alternator on starting the car there i confirmed i drove the car there without the fan on so the rewire tried connecting the fan but only one fan works, its double cell radiator so he had to create a wire from the of the top of the engine to the fuse board before the 2 fan could run but it making a loud noise.....Is the connection right and what could be the reason why the fan is making noise and it runs faster than before....

Nice car you've got there Sir, I hope you're really taking care of her. There was a time I wanted to get that same same but it was just too low and has small cabin space for my liking. I needed it for a sporty redesign and tune-up project I intended embarking on.

CAN SOME ONE HELP ME WITH WHAT I NEED TO DO TO RECTIFY ERROR P0948 ON MY HONDA EOD 2003

Cryomancer:
What are the symptoms/changes you observed in the vehicle first?

Common Causes of P0948

Faulty hydraulic pump relay
Wiring issues in the relay circuit
Voltage spikes in the circuit
Corrosion or damage to electrical connectors
Issues with the vehicle's battery or charging system

Check the relay and probably get a replacement to test on your vehicle.

Anticannibal:
Sorry the right code is P0498
And the current obvious symptoms are hard starting when the engine is hot or cold, and lack of power when I try to accelerate.

Converted?

Cryomancer:
I don't understand how the two fans were supposed to work if you didn't on your AC. was your AC on when you noticed none of the fans were working?

Only one fan is meant to cool your radiator, while the other one picks and stops simultaneously when your AC is on.

Rather than allowing the rewire to by-pass the fan, why not look for the root cause of the stoppage and fix it. I suspect a thermostat issue here.

Macmilla:
In my car, the fan comes on and off as the ECU seems fit. This means that a lot of times, the fans will be off and that is perfectly normal.
You didn't mention any clear sign of overheating, so I'm pretty sure your engine didn't overheat, especially when you said the temp indicated on the dashboard didn't rise.
You had a radiator leak, but you didn't mention if you fixed it.
Lastly, stay far away from whoever did this connection for you. He is a demon of destruction. Find a good electrician that will correct that nonsense and fix the actual problem. PLEASE STOP BYPASSING ANYTHING IN YOUR CAR.

Aka acura tsx old model. Check the fuses at engine bay or whwrevee they hid it in the car.

Gombs:
i've cehcked..still

rapheal5:
Well I bought the car used and only one fan was working when I bought it and ac isn’t working so it was after I fixed the ac that the second fan was connected… Can anybody suggest a good Rewire that can fix it back to normal here in Abeokuta ogun state…

Alaye dpnt bother doi g all that,my crv 2009 model fan was connected direct from berger,till i sold it,no overheating.pks look at.your hoses for cracks.naija is a dead country

rapheal5:
Thanks boss

2cribz:
The hose going into injector mouth na koko. Check am for c,racks,leaks or water drops.b4 u leave ac man place,make sure the ac is turned on for 30mins and monitor temp guage.if e pass middle.e mean say the hose don sapa

Note that a lot of the advice you will get here is nothing but poisonous garbage. It is on you to choose what to take and what to discard. Nobody owes you anything and you don't owe anyone anything. My people say that if the rat joins the lizard under the rain, if the lizard's body dries later, the rat's not will not. Some people will abuse a car for years and then sell the car when it is close to the grave. They will then come here and shout "I did it and I never complained till I sold it". Then the buyer will befriend a mechanic for life. All of us will still come and be shouting Nigeria is dead when we are the murderers.
