How long will a car engine work underwater?

A while back we promised we'd do it - and here we are, fulfilling that promise. In today's video we see how long a slightly modified Lada engine can work underwater.

It wouldn't be a Garage54 video without Vlad's signature *_"OYOYOYOY!!!"_* lol
Someone should make a compilation or remix of them 😁

Dunk the engine after disabling the water pump, and see if the water surrounding the engine is enough to keep it cool.

probably needs new HT leads - old ones get cracked & when the crack hits the water it will short - as soon as you take it out of the water it will no longer short

This is how they used to water cool engines before they invented radiators

I never wanted a Russian car before seeing a Garage 54 video.
Now I really want a Lada, I do not care how they look,
as long as they are as dependable & durable as they appear to be on here LOL

These videos are under appreciated, one of the most interesting and entertaining car related shows on the tube.

This is more like “how to make a hot tub with an engine” Russia style

First video: "let's hydrolock the engine" inconclusive. Second: "let's dunk the whole fu*king engine"

The water between the plug´s electrode and the motor casing has a much lower resistance than the spark-plug air-gap. You´d need to isolate the high voltage connection to the sparkplug with epoxy (several millimeters clearance to water and no metal content in the epoxy). I´m pretty sure it would work then.

Next Project: Drive a Lada on the bottom of a lake. Like if you agree!

Hahaha, this has easily gotta be one of my favorite channels on YouTube. You guys are awesome!

Not all Russian men are named VLAD - some are named IVAN

Wow, this is really interesting!
As long as you've sealed everything up and have got the snorkel attached, the engine should be perfect happy running fully submerged.
What's intriguing here is the situation where the engine stalls when submerged, but then repeatedly starts up again when hoisted out of the water. This indicate there's absolutely no water ingress anywhere. If there was water leaking in, you wouldn't be able to restart the engine after the first dipping.
There's only one thing I can think of being the culprit here. Arcing in the HT cables when the engine is submerged. Mind you, as the engine fire up happily once out of the water, there's nothing wrong with the actual cables, they are fine. What we are looking at is a bad ground connection somewhere between the ignition coil and the spark plugs. Up in the atmospheric air, the resistance added to the HT circuit by the bad connection does not affect the running of the engine. However, this changes as soon as the ignition system is in the water. Suddenly, when submerged in a liquid with a higher electrical conductivity than air, the resistance in that bad ground connection makes a difference. The HT current will always travel the route offering the least resistance. Usually this is through the spark plugs. But in water, with the added resistance, that is no longer the case. The current will instead form an arc, and jump straight to the engine block. Basically, the ignition coil is shorting out. Then, as soon as the engine is back upon the air, the best route for the HT current is again through the spark plugs, and everything works fine.
Please, clean and repair the ground connection at the ignition coil, and repeat the experiment. I am willing to bet it then works fine!

daddy why cant we get a pool for our house like that

garage 54: this is for scientific research not for fun

It is worth doing a test with a diesel engine, there is no problem with the ignition.

The takeaway I get from this channel is that Lada makes the best, most indestructible cars in the world.

Years ago we took an old Jeep Gladiator, stripped off the body, and added some 33 inch tires. We drove it into a river to see how long it would run. No waterproofing was done to the engine. The plugs and distributor were submerged and it ran perfectly. Even the alternator worked under water. We stopped when the carb was submerged, with only the air cleaner above water. It never missed a beat. Those old distributors were notorious for missing when they got wet.

Do the independent brakes - 4 master cylinders connected to a joystick in an X layout and the master cylinders separately connected each to a respective wheel. Drive, and use the joystick to activate each brake independently (or semi-independently, I dunno, get creative)
