In fact, in as little as 30 days, the gas inside your mower will have degraded and become significantly less combustible, and therefore, less effective. That’s right, gasoline can go stale, and it doesn’t take long. Let’s now talk about what you need to do. Luckily, preventing vapor lock is a relatively simple task. Vapor lock is undoubtedly one of the most annoying issues that your lawn mower can face.
ENGINE VAPOR LOCK HOW TO
How To Prevent Vapor Lock in a Lawn Mower This is especially true if it happens during the summer when the heat is already a problem. While the summer heat is the most common cause of vapor lock, leaving a mower near very hot objects such as a working barbeque or fire pit can also increase the risk of your mower developing a vapor lock. Without fuel, the engine either stops working entirely or starts and stalls, both of which can be highly annoying.

The worst case is that your engine is shot, and you need a new one. What’s the best course of action if you think you’ve hydrolocked your engine?ĭon’t wait – because the longer you do, the better the chances you will end up with corrosion damage. It’s Probably Better To Go Around That Puddle – Not Through It Don’t drive through a puddle. In a worst-case scenario, a hydrolocked engine can cost anywhere between $3,000-$8,000. In this case, there’s really nothing you can do other than salvage what you can and replace the rest. The other possibility is that there’s a lot of water inside your engine. However, if a secured area is not available, the cleaning can be done later. It is vital to wipe the cylinder walls to get rid of dampness that may cause damage. Though, in an emergency situation, you should be able to just dry yours off. You should also replace the spark plugs with new ones. You should notice water spewing out of one or more cylinders. This involves removing the spark plugs, starting the engine, and then revving it while it’s in park. If you were moving at a slow rate of speed when the RPMs were low, you might be able to clear the system of water by yourself. Whether a fix is possible depends on the amount of water that has entered, as well as how long it’s been there. If you don’t act quickly to remove the water, your engine will rust, which will likely render it useless. This is precisely the case with hydrolock. When associating the words “metal” and “water,” the first thing most of us think of is rust. If you were going fast when the hydrolock occurred, where the RPMs were high, severe damage might occur. In this case, you need to act swiftly to remove it before it causes corrosion issues. While the RPMs are low, such as when you’re idling or moving slowly, only a small amount of water may enter. However, the speed you were going is what usually determines the extent of the damage. Hydrolock can be very harmful to an engine and may require its replacement entirely.
ENGINE VAPOR LOCK CRACK
However, remember that if this happens, it likely means you have a severe issue inside your engine, like a blown head gasket or a crack in the block. It’s also possible for the hydro lock to occur from other liquids, like oil or coolant. This is one of the reasons that flood-damaged vehicles are often totaled afterward. What kind of situation can result in water entering the cylinders? There are many examples, like driving in a downpour or going through a deep puddle. This will result in crashing or knocking sounds inside the engine that will last several seconds, followed by it shutting down. So, when the piston attempts to compress it, all of the cylinders will stop at once. Why? Because water is less compressible than the air/fuel mixture inside. When a piston reaches the top of its travel range, if the volume of water inside is more than the amount of space left, hydrolock will occur.
This happens when too much water enters the combustion chamber. The actual term is Hydrostatic Lock, which has been shortened to hydrolock. What Causes An Engine to Hydrolock? Do not drive through puddles, as it may cause a hydrolocked engine.
