Rain, Rain, Rain


Recommended Posts

Its been non stop rain here on Long Island for a couple of weeks.

Today I had the occasion to run through about 2 feet of rain water. I let a car go through in both directions before I attempted the pass. The water was about to the top of their rims... so maybe it was not quite 2 feet, maybe 18 inches. How deep do you guys think we can go before we hydrolock the engine, where is the safety margin? Maybe I need to go an measure how high the snorkel and PCM is.. Any ideas?

I know that both the intake and the exhaust have to be above the water or you'll have problems. I wouldn't drive in 18" of water very long or you'll damage the electronics (as you already know). You also have to make sure that water doesn't get into the CV Joints, ball joints, tie rod ends etc. You need one of these. (notice that both the exhaust and intake are elevated) [attachmentid=2559][attachmentid=2560]

You were in deeper water than I would ever attempt to drive through with a car; 12" is my limit. And less than that if others are pushing through and creating waves.

Mike,

I'd guess at 2' you were close to the limit. Last time I drove through water much less deep than that, I wound up with a rusted caliper piston bore 6 months later. I found it when the piston hung up and I had a brake dragging. The bore had to be honed and the rusty pistone is still on my work bench. Come to think of it, I don't know what I'm saving it for. That was probably 20 years ago. :blink:

Yeah, it's 10' X 3' with about 3' X 2' works space left. :lol: I gotta get around to cleaning it up one of these days.

Ranger, get rid of it! Get life! We rust much faster than calipers. :lol:

I think I will grease my ball joints this weekend after re-reading this, :lol: Hopefully my rear suspension compressor did not go under....and ingest water

I had a line of cars behind me, otherwise I might have turned around

18 inches?!? Courage, thy name is BodybyFisher.

Ya got me thinkin' and I went out and measured: center of exhaust tips are 12" above street level. I don't think I'd chance anything much above 6 inches. I'm such a wimp.

Regards,

Warren

I made a big mistake, following the masses into the water. Figuring that wheels are 16 inches, it was quite deep... I should have wimped out and turned around

I hear ya. I've been found (but not stuck) in that position.

I don't know about turning around though. You might have been T-boned by one of these . . . . :lol:

Exhaust tips under water are not a problem. It'll just bubble like a speed boat. You need to be more concerned about the calipers going under. That was my problem. Got water in the caliper (not sure where as it is sealled) and the brake fluid being hydroscopic absorbed it and rusted the piston & bore. If that water was really 2' deep. I'd give some thought to bleeding the brakes soon.

I have forded a stream before in my Seville. As I recall, exhaust tips were under water, as was the rear air compressor. No problems. In fact, I forded it twice...once going and once coming. It was at a campground, and the stream was about as wide as the length of the car. I have pictures somewhere...

Larry is correct that exhaust being under water is no problem. We've been on two Jeep Jamborees with a 1996 Grand Cherokee. The water level of the river was halfway up the side doors (about 30" probably). Air intake snorkel was temporarily diverted to the upper rearmost part of the engine bay to accomodate mud/water for the event. No problems with suspension or brake components.

That was the demise of my '93 STS, my wife drove it through high water after a police officer had diverted her down the street that did her in. I do not know how high the water was when she drove through it, but it was up to the top-bumper area when I saw it. The engine became a water pump and pumped water from the street into cylinder no. 8 (nearest the intake), and cracked the piston and tie-rod.

My neighbor bought the car for $ 500, tore the engine down, but decided to forgoe the rebuild when he noted a crack in the aluminum block.

There are days that an Escalade would be handy, like when you need to go through standing water. SUV's aren't ducks either, but at least they have more clearance.

Yesterday after a commute I arrived at the intersection of this highway and that highway to find a semi-tractor trailor was crashed in the intersection, with police and fire arriving, and 12 lanes of traffic beginning to build up. Hopefully no one was hurt.

I was jealous when the SUV's around me U-turned over the curb and across the median and escaped the traffic jam, but it seemed a bad plan in the CTS. As is turned out I was able to creep past, then work through traffic and get back on track without a huge delay anyway.

When I was growing up, we lived next to a viaduct, where the street ran under a railroad track. When it rained, the street below the track would flood with standing water. Cars regularly drove in to this and stalled out. Then the driver would climb out, and stand with hands on hips studying the vehicle while wondering what to do next.

It would have been fun to maintain a sign that showed how many cars that viaduct had destroyed :D

  • 2 weeks later...

About a week ago I was on my way over to the walmarks and I decided to take the long way of course and I was driving and hit a really deep amount of water in the road totally by suprise and was being watched by a sheiff I was a mess and almost lost control. I have never seen any water in this area of the road before and its as your coming down from a steap hill :(
