Car repairs can be a downright pain, especially if you have to shell out hundreds of dollars to your local mechanic.

To find out whether or not some of these old farmer car repair hacks work, the folk at Donut Media put them to the test. The hacks included using an egg to stop a radiator leak, using Redneck Rain-X to waterproof a windshield, using old oil and Coca-Cola to clean rusty car parts, using pantyhose in place of a serpentine belt, and using bread on a pilot bearing.   

Do these hacks sound absurd? Yes, they do, and here is what they found out.

Hack No. 1: Using an egg to stop a radiator leak

Has your car’s radiator sprung a nasty leak and you don’t have any tools to fix it? If so, then an old farmer trick states that you only need a case of eggs. To be specific, the trick states that cracking a raw egg into the radiator could potentially stop the leak. The thought is that the heat from the radiator will cook the egg and the high pressure of the system will seal up the hole so that you can get to a repair shop.

Does it work? According to the video, no, it doesn’t. The Donut Media boys found that the leak in their test radiator still remained and even started spewing out bits of cooked egg. Well, that’s one way to poach an egg in the morning.

This stuff makes the glass somewhat water repellant so that you can see better during a downpour. However, if you don’t have access to the miracle solution, then you can always go the “Redneck Rain-X” route.

This method involves putting chewing tobacco into a sock and then soaking it in water. You then wring out the sock and then apply it to a windshield with the tobacco still inside. The disgusting solution is supposed to coat the windshield and make it repel water.

Did it work? Kind of. Donut Media’s testing showed that it kind of worked, but it also left a film on the windshield afterward. In that case, they called it a fail.
