Greenhorn,

Something is amiss here. Maybe the service center mechanic accidentally cranked the water logged engine after correcting the electricals, replacing battery and before replacing the contaminated oil, resulting in a hydro-lock. It is definitely not possible that the engine could be damaged any other way.

If there is someone who could download and read the ECU logs for the past few KMs, there may be a way to ascertain the actual timeline of events, if at all there is a time stamping. Sounds like a long-shot, as I am not sure how much detailed information can be obtained from the ECU, provided that also has not been replaced! But it's worth a try.

Peace.

Regards,
Abhishek

Looks like some moron at the service centre tried to start the car. Otherwise it's just a matter of replacing the oil, provided there is no rust inside. The engine will not blow unless someone tried to crank it with the water inside the pistons. I remember my Works manager explicitly saying this, when I asked him why they are taking in cars submerged upto the engine level for repairs, instead of writing it off.

That's my guess as well, but the guy says the workshop insists they found the car that way. Right now, it is his word against theirs, so was wondering if this could be proved some way.

Would this be possible for a ford figo, esp with a dead battery? Is the memory which keeps the logs volatile - hoping someone here can answer these questions

Nope. Perhaps take an OBD scanner and check if any permanent DTC is stored. Apart from that there are no such logs. Even if you find it, sicne the job is already done, it will be difficult to quarrel with the garage. If he has been able to convince your friend to go in for an engine overhaul, then he will definitely be able to convince that he is not at fault. Permanent DTCs will not be cleared even if the battery is removed. Not sure about how it is in a Ford, but usually if an engine has seized due to hydrolock, the Crankshaft and Camshaft position sensors will throw up errors at least. It should be stored as a permanent DTC with a time stamp and a dump of all the other data related to the state of the car during the occurrence of the error. Only the temporary ones will clear out when the battery is removed.

What actually happens inside a wet-inside engine if someone tries to start it?

Since water is not compressible, the engine fights a losing battle against water, tries to compress it, fails and the weakest part in the link will bear the brunt. Say, a bent connecting rod, broken or bent valves(sometimes) or even a broken crankshaft, if the con-rod is strong enough to transfer the force to the crankshaft. But water inside an engine isnt a good thing at all.

Dear All,

This is how the car came out from Maruti Service Masters, Guindy, Madras. A truly fantastic job. More than the refreshed look, the car performs very well mechanically. The paint still looks new, only because I do not wipe the car at all, except to clear bird droppings and tree sap. Else, it is thoroughly cleaned very rarely, that too to remove excess muck and dirt, and is fully washed, polished and wiped only during periodic services and other intermediate water washes at MASS.

Note : You can still see the flood water marks on the building in the background. The water had risen to 5 feet from the ground level. The car was submerged up to half the windshield level on Dec 2-3. However in this photo, the car itself is parked on a slightly higher platform above ground level, elsewhere in the same building. The original parking space is seen in the second photo, occupied by my Red F8D Alto.

We just completed a ~1900 KM 8-day round trip From Madras - Kanchipuram - Tirupati - Yelagiri - Tumkur - Hassan (Hoysala Temples) - Srirangapatna -Mysore. The trip mileage was ~19, for ~100 litres of petrol consumed, all tank-fulls. The car performed fantastically, without any electrical or mechanical issues whatsoever. The best mileage was on the night drive from Hosur (Reliance) - Madras (IOCL). 300 KM between tank-fulls - 23.24 KM/L. Cheers to Maruti and MSM!

Back to winning ways! Kitna Deti Hai? Let's go!

Peace,

Regards,
Abhishek.

Default Honda city flooded, Please advise

Hello guys,

My honda city was flooded while parked outside my residence on on Aug 31st. Water had filled inside 3 inches upto carpet and mats.

I took it to honda asc the next day and left the car there because airbag light was constantly ON(it still is). Honda asc has advised only to change srs module which is under gear lever for which I filed insurance claim on 5 sep. Until claim is approved I got my car home today but car runs pretty heavy as if it still has water inside though its been dried up by vaccum at honda. Why is that?

I went through other similar threads where entire service including oil change etc is recommend. Why did honda asc not recommend the same to me. Please list all that should be done to get car in original condition.

The car has run 21800 kms since purchase date of 1 Aug 2012.

For srs module honda asc is asking Rs 19000. Is this correct estimate?

Car was last serviced at 20071km 2 months ago.

^^ You could yourself check the quality of engine oil and am sure it will be in great shape.

If Honda hasn't recommended any service it is because they know it isn't necessary.

Do you get a damp kind of odour inside the cabin?
By the way , the kind of water shown in the pic is normal fare on flooded streets/roads these days.So not to worry.

I would recommend that you get the
1.carpets removed, shampooed(anti bacterial foam or equivalent) ,dried
2.floorpan cleaned and dried , and disinfected

Should cost you approx 4k at a good detailer.

The airbag module is the first casualty during flooding.It does cost a lot .

Please get the clutch and gear oil checked. Also check the rear drums, where water seepage might lead to a jam, which can contribute to a heavy feeling when in motion.

Clutch is fine but car feels like its carrying a CNG cylinder, means weight not only in boot but overall. Though I do not have cng installed and car runs on petrol only. Does suspension needs to be checked?

Let me give an opinion from my side too. I bought and restored a flood damaged Hyundai Getz. With that knowledge in mind, here are my observations.

If your car lacks acceleration and feels as if it is weighed down, it is not the fault of suspension but the fault in power transmission. A simple diagnosis you can do is to jack your car up and turn the wheel. It should spin freely for two three rotations (atleast). If not, there might be two reasons. One is the wheel bearing. It is the most likely reason. Wheel bearings need grease in order for them to function smoothly. Grease might have got washed away in the water. Wheel bearing is not that expensive and hence get it replaced. The second reason might be the brakes. The brake drums should be opened to inspect for mud deposits. It is not pure water that flooded the car and hence the mud in the water might clog up between the brake drums and the brake shoe. It might create a resistance. Did you get your car pressure washed at least once after the flood. Pressure washing will clean off the deposits and not having done that will only create problems due to the lodged mud. Third point of inspection is the clutch. Clutch usually softens down and gets damaged in the flood water. I had a clutch that got stuck onto the pressure plate and was not releasing. After keeping the car in idle for many hours, it loosened up but the grip on the clutch (read: clutch was not engaging properly and even with high revvs on the engine, the speed of the car was very little) was not so good. Hence, I got my clutch replaced. Then of course, the transmission fluid and the engine oil needs inspection.

Bearing that in mind, I am guessing the point of failure for you is the wheel bearing. Change the wheel bearings if possible. They are not that expensive but it might be the culprit. You don't need to get the brakes inspected. Just get the car pressure washed. And the engine oil, transmission fluid will all be fine. Any ASC will definitely check for them and if they did not report it, then it must be fine.

If your car is wallowy, i.e. excessive vertical movement like a Volvo bus, then your suspension is giving up. You will also notice a dive of nose under braking. If you see those factors, get your suspension changed.
