Driving a flooded street

Where could the sound have come from?

BTW, CVT tranny. I drove the car the day after and everything felt normal. No problems sa shifting and braking. Ano ang dapat kong ipa-check?

did you switch off your ac before going deep?

it's probably a slipping belt. serpentine.. aircon.. it was slipping because it was wet.
nothing to worry about, as it goes all back to normal when dried up.
well, maybe check and tighten up the suspect belt afterward if needed, is all.

what else to do? check my post above, # 78. back then, i also drove my car in ondoy's heavy flood, with water also up to the car doors.
of course, my car back there was an innova.
heh heh.

i was lucky. after more than ten years afterward, innova still runs well, with no problems.

when in doubt, drain and replace (engine, trans, diff oils) or clean and re-pack (wheel bearings and brakes).
if you are lucky, you wouldn't see that oil + water really looks like coffee from nescafe 3-in-1.
good luck.

Malamang nabasa yung pinakamababang bearing mo kaya dumulas yung belt.

Nung natuyo yung belt, ok na.

IMO... I think you can call it "old school" nowadays.

Been doing it since my college days... twice ko tinawid sa Espana yung 90's Lancer ko noon.

Salamat sa mga response.

Di ko na maalala if the ac was on but it probably was because my windows weren't fogging up. Ano ang magiging issue pag buhay ang ac? Other than the usual pa-maintenance, wala pa kong experience sa mga pa-repair.

My take away from all your replies is to have the brakes and wheel bearings checked and cleaned. Check belts na rin. Sasabay ko na rin pa-underwash.

CVT fluid rin pala.

I don't remember the last time I saw a car bearing na pwede linisin/lagyan ng grease...

Most are sealed. kapag umingay, palit na kagad, walang repair.

when the AC is on, the big fan in front will be spinning because it has to cool down the condenser.

when that water hits the fan blades, the blades could go south or the motor can trip the fuse and you could be stuck somewhere with an overheated engine. seems like you didn't go deep enough.

I'm thinking that the dual fan setup of the honda city is abit higher from the ground. honda city nga ba bro?

Does the Mirage have 2 separate fans or 1 variable speed?

It wasn't too deep I think because I didn't hear water sloshing against the bottom plus I made sure to drive slow enough to avoid splashing. Mirage hatch ang kotse.

Thanks for that bit of info. I wouldn't have thought that that's the danger of driving through deep water with the a/c on. Akala ko ang magiging problema is it would suck water in.

1 fan lang. It's variable speed AFAIK.

just switch off the ac next time. its just less than 5 minutes going slowly sa floods.

as for the fluid changes. I don't think its necessary. the cvt unit has a breather just on top of the air box(air filter) if you remove that air box and its dry then its not necessary to replace the cvt fluid.

I just hope the cvt level port is closed real well. thats one way water can get inside the cvt unit. though i'm not sure if you've got one.
