You are in the Toyota Echo
What is this discussion about?
Toyota ECHO, Coupe, Sedan

I just bought a 2001 Toyota echo 2 days back.
I notice that when I was parking the car, there is a fan turning on and making a lot of noise. It turns on and off intermittently. Is this normal, it seems I have never heard such a loud fan on other cars.
I should add that I am a complete newbie in this, and this is my first ever car. I apologize for any stupidity in advance.

Oh my! No need to apologize. If not for "stupidity", most our our maintenance & repair discussions would close down.
Fortunately, there are a lot of folks here who know what they're talking about. I'm not one of those... I'm like you... but welcome to the Forums, and hopefully someone will have a bit of advice for you soon.
(no insult intended... *I* have to ask questions about everything more difficult than checking the engine oil level)

That's probably just the radiator cooling fan going on and off. What happens sometimes is that when you park a car after running it for a while, and you shut off the engine, there's a phenomenon called "heat sink" that occurs, which means that for a brief time the engine coolant temperature actually goes UP a few degrees, even though the car isn't running anymore. Basically, the hot engine is heating up the coolant, and with no water pump circulating the coolant, it's a natural thing.
So the coolant temperature sensor, sensing a rise in temperature, signals the cooling fan to go on, which it is allowed to do even if the car is shut off. Once the cooling fan cools the coolant down, it shuts off. Since the "heat sink" might go on for a bit, it's possible that the cooling fan might have to turn on two or three times to get the coolant temperature down.
The fan should shut off pretty quickly though---if it runs on and on, then the sensor or relay is probably defective.

Thanks a lot. Yes it turns on and off pretty quickly. The sound is a little loud though which kind of scared me. Also, I noticed it happens more in reverse, but that can be placebo effect in observation. It happens to me when the car/engine is still on; I was just trying to park the car then. I will look for it more often.
Just a follow up question on Maintenance now:
The mileage of my car is 39k. What kind of regular check up should I do and maintenance?
Thanks in advance

check your air filter change every 30k miles
check sparkplugs change every 30k miles
look in your owners manual for more things to do
Check the coolant level in the overflow bottle. I also think your fan going on is normal.

thanks a lot guys!
and edmunds schedule is guide is really good
Last question for now : I got my car checked and everything. The mechanic told me may need to change my battery in near future.
These are the numbers from the test:
Is this something that I should do it right now, or can it wait?
NY winter is coming in a month, so I dont want to get stranded.
Appreciate all this.

How old is this battery? Usually they should be good for at least 3-5 years of hard service.

Hmmm 12.4 volts should be more like 13+ volts at least at rest. But maybe its OK if it was done under load. Was the alternator belt good and tight? (battery wont charge if not)
Personally I never change a battery until it goes out. My ECHO battery went more than 7 years and its cold where I live. It easy enough to get one at Pep Boys and install yourself.

hmm..will look at it. When the test was done, car had not been driven for more than a month. The previous owner had taken the car off the road.
The battery is original I think, so 8-9 years old. But I am not sure, not asked the prev. owner if they had changed the battery or not.
