My fan is running for a while after i turn the engine off. it never did this before. any ideas??

mezzerTL-S

check your radiator fluid, its probably low. But wait till the car cools off completely!!!!!!!!

acutee

Something is overheating or your cooling system is poor. check coolant, oil, transmission fluid, fan, thermalstat.

thisisnotdave

Doesnt mean the you coolant is low necessarily. I would check anyway (you should check it ever time you fill up, along with oil, trans, ps, and brake levels. Not that most people do, just always a good idea. But if your levels are fine, and your temp gauge doesnt go past 1/2 you're fine. Also from what i've heard I'd only use Honda/Acura type 2 antifreeze.

It could also be a faulty fan switch. Many have had that problem as well. Always check your fluid level first. Also is your temp gage higher than normal at all?

ftLauTL

Ive had this problem recently as well

and when I check the coolant level the resevoir behind the driver side headlight is always empty. So I refill it with Honda Genuine coolant

This afternoon is the second time ive had to refill it, but if it was a leak I should be able to find it right? I mean I would be able to see fluid leaking under the car or even from the radiator

I'll keep you guys updated after tommorrow

coolant is fine, all other fluid levels are good too. i'm going to check out the fan switch/relay on my day off tomorrow.

law321

How fast are you going thru coolant? is there any white smoke coming from your exhaust? if so you could have a head gasket problem.
check your oil to see if it is shows signs of coolant.

Have the coolant system pressure tested to find the leak
check if engine oil is way above full and possibly grey and foamy
Do the same check of the radiator itself- remove cap only when dead COLD engine
look for grey or foam or oil
Check all hose clamps first- leaks at idle at not the same as leaks under driving pressures

A gen3 TL recently had a lower hose clamp break ,and fling part of itself into the radiator- leak-leak leak- not seen- bottle empty- then poof smoke then- luckily warranty covered all

Hey Kris- does the TL have a port for fluid discharge when wp seal goes- like other normal cars would have?

fsttyms1

You know, i honestly dont know. I havent looked. I would assume it would though

Any recent work done or has this just recently started ? As previously mentioned, a pressure check of the cooling system is your best bet. There could be a small leak somewhere while operating under pressure. It's possible that air may be trapped or perhaps your coolant ratio isn't correct. The cooling fan is actually being told to stay on for a short period of time after the motor's shutdown when the coolant thermosensor detects an overheated condition. This is by design after stressed conditions such as if the motor has been idling for a long time or has been subjected to heavy stop 'n go or pedal 'da metal driving.

i think im having a blockage problem. now my ac is getting warm at lights. ill try to clean the gunk off my radiator and promote better air flow? ill also chande out my coolant for good measure. anyone got an ignition swtich i can buy? mine is bad and it already has been fixed.

ign switches are 40 bucks, dealer item- or call the dealers who sell to us cheap thru azine
Sometimes the dealer will replace it again since it was a recall item- ask the SERVICE MANAGER

SOFT brush to remove bugs on radiator but thats not your problem.
The fan runs on a temp sensor- if its connection is grungy or the sensor died- which happens to all types of cars, fix the problem- then think coolant change if over 5 years on coolant. AC not cold- check the ac sight glass for clean or is it milky
There could be a thermostat prob too

How many miles on the water pump?
Low flow will promt the other issues you are having from loss of fluid ......
Has it been pressure tested yet?

Well the problem happened today after I got to my girlfriends apartment complex, probably not evena 10-15 mile drive. The problem is, is that this coolant boiling up due to such extreme heat I guess is only A. when its really hot outside (which is everyday in South Flo) and B. the AC has been on. Im thinking its the fan switch because Ive had this problem before where the fan behind the radiator on the left, which is the condensor fan is not running, only the radiator fan is. So in essence the radiator fan is doing all the work. Im taking the car to the dealership tommorow and I hope its not a big deal or maybe they'll fix it for free because I had alot of work done in the coolant/radiator section if you will about 6 months ago


fingers are cross boys...

ftLauTL

Im hoping they will check the ignition switch, fan switch, water pump etc.


Im thinking its the water pump because apparently I checked the maintenance history on my vehicle and the previous owner did the 100,000 check at I belive like 98,XXX and they didnt change the water pump because it was still in working order. unreal


So if my assumption is correct, my original water pump from the day of production, 168,000 miles ago finally gave up and now I need to replace it.

law321

Got a ph # where i can get an ign sw. called the dealer today and spoke to the svc mgr. no can do on the "goodwill"

01tl4tl

then call the parts dept and ask how much and how long to order one for you
Strange a service dept would do the timing belt at 100 and not replace the water pump- thats VERY strange

ftLauTL

Well I dropped off the car today since I dont have class

I'll let ya guys know what the dealerships diagnosis is

I kinda doubt its the pump. Id bet on a thermostat, and that it needs a flush with fresh coolant.

Hopefully its something simple and wont cost me a fortune

it kills me not to have my car, seems like your world comes to a grinding halt

thermo stuck-my bet. I've had that happen, same symptoms/temp. gauge shot up.

Apexi2000TL

For your AC getting hot when at idle, check your system pressure. That is a first sign of low AC refrigerant. As for the fan comming on after shutdown, sometimes normal. The fan will shut down even if coolant still hot. For some reason there seems to be a restart in the PCM for Temp system check after shutdown. Then the fan will come back on.

ftLauTL

Well its been a few days since I got her back, but I got held up with school and work


Anywho it was just the condensor fan burning out and not helping the radiator fan in cooling efficientely. So Acura even picked up the entire tab in that it was covered under warranty

Guess it was my lucky day

Mine has done this maybe twice. Maybe its time for a Mugen fan switch, Mugen thermostat, and Mugen radiator cap.. lol

fiznerch25

mine has been doing this lately, mainly after hard driving. The temp gauge shoots way up when ideling or slow driving . I'm gonna flush and change the fluid to see if this fixes it. Any other suggestions or ideas on what it could be. the coolant levels are fine and the fan works obviously since it is staying on after driving

ftLauTL

Ya my temp gauge would shoot up as well especially after long drives or just it being really brutal outside as far as the heat goes


I think I cars just have a weak radiator/condensor fan setup. Thats my two cents
