just had to drive through a couple of floods about 2-3ft of water, in a mates hire car, car seems ok, would there likely be any damage? a lot of other cars were getting stuck, but we just went through slow at about 6000rpm.
 
Same here, Swindon is a bit flooded, so I just used a bit of clutch and lots of revs.

I expect a tide mark around the car now :D

hire car !

you should have just went full pelt and prayed that you aquaplaned over the flood

wudnt 2 or 3 foot make you inside the car very wet :eek:
 
Slow at 6000rpm?

Wouldn't you of been wheelspinning like mad under the water? Or if you was in a high gear, just slipping the clutch like crazy?
 
As long as no water got into the engine (via the exhaust - which is why high revs are used or through the air filter) then you should be ok. If you get any electrical problems you'll know why.
 
if the water goes over the air intake it will suck water in to the cylinders and as fluid is non-compressable you get hydrolock and some very bent conrods

also if it is a petrol efi then you can screw up the ecu and other electrics

A bit? You seen down by walmart and the manor, was past knee deep when I was walking down to starbucks, nearly swept me off my feet.

Real glad I didn't have work.

Revs are bad. There is no advantage of High RPM.

Just creep through them in 1st going slowly, fair bit more than tick over (enough to give power on 3 cylinders if water starts messing with the letrics).

If you suck water and you're doing mega RPM then you are going to hydraulic it, if you're going easy the repair bill will be cheaper.

The real trick is to remember to dry your brakes afterwards, tho do note, some cars will do silly things if you press the brake and throttle together.



Here is the remains (Gudgeon pin and 1/2 a con rod) of an engine that was hydrauliced after going through a flood with high RPM (the block was in 2 pieces), alongside the remains of my old Barton which was crushed by a Big Typhoon:

I can't think of anything worse than crawling through it, you're going through it at full height, causing a raised wave at the front of your car.

You want to go through it at a decent pace to push it out of the way.

Just a bit eh.... Got canal?

My old man thought it would be quicker to walk from the Great Western Hospital dual carridgeway because we were sat there for agggges, a 15min journey home took 1:38mins :rolleyes: He got wet and I got home before muwhaha.

I've always understood it as you're meant to have high revs when going through water. Just keeping enough clutch to be going forward by not so much that you'll be wheel spinning underwater :p
 
update on what happened, was in town earlier with mate in hire car, said about that bit, now had to go around the edge of swindon in my own car, ended up on a part of the ridgeway to get back home, went through about 4 or 5 3-4ft deep puddles, i don't even know how my car is still running. but we made it :cool:
