A gas agriculture engine (such as a gasoline tractor engine) which has seized can be freed-up easily using Engine Release

A gas agriculture engine can seize during storage or long periods of disuse. The best treatment for a seized agricultural gas engine is Engine Release.

These instructions are for any agriculture machinery with gasoline engines.

Regardless of the type of engine and vehicle you intend to work on we have specific instructions for your project on our site. Click the links on the left-hand menu to be directed.

Warning: Read safety warnings on the Engine Release container before continuing. Click here to read the safety information online BEFORE treating a gas agriculture engine with Engine Release.

Engine release will damage paint finishes.

Before working on your tractor, combine, swather, etc. make sure it is on level ground with the parking brake on or the wheels blocked, so it can't move, with the transmission in neutral and the fuel supply turned off

Preparing your engine for an Engine Release treatment

Most farm equipment has vertical exhausts. If you think your gas agriculture engine seized because rainwater got into it by the exhaust pipe, remove all your spark plugs. If corroded or seized, a few drops of Engine Release on the plugs' threads will make frozen plugs easy to remove. (Let it soak in for 15 to 20 minutes.)

It's a good idea to identify each ignition wire with either a numbered tag or tape so as not to mix them up when you reconnect them.

To empty out the flooded cylinders, purchase a large plastic turkey baster and about 24" of clear plastic hose that will tightly push fit over the end of the baister and still have a small enough out side diameter to pass through your spark plug holes.

Now one by one check your cylinders for water using the baster. Also if you have failed to free up your gas agriculture engine previously using Mystery Oil, vinegar, water, ATF, diesel fuel, WD40 or others, it's important to remove all traces of the above with your baster so as not to dilute the Engine Release you inject into your engine.

It's a good idea not to try and force more hose down the spark plug hole than is required to just touch the top of the piston so you can remove the majority of the water you may find. Pushing more hose into the cylinder than is required will just force the end of the hose to curl up in the air, not touching the water and defeating the purpose of this exercise.

If your gas agriculture engine seized because you have not used your equipment for a while and it was stored indoors or under cover and you are sure only airborne humidity entered your engine, don't bother with the turkey baster.

Once you've got your ignition wires disconnected from your plugs and identified and you've removed all your spark plugs, use your injector bottle to wet each cylinder with 1 oz of Engine Release once a day for three days.

The idea is not spray Engine release onto the top of the pistons, but by using the injector bottle depositing the Engine Release between the cylinder wall and the edge of the piston crown in each cylinder. If you allow the Engine Release time to seep in and around the gas agriculture engine's rings over a period of days you will easily free up your gas agriculture engine.

This photo is of a 4�" diameter cylinder, here you see 1 oz of Engine Release is more than enough to cover everything required and then some! Refreshing the Engine Release in each cylinder daily keeps the corrosion dissolving additives active while the liquid Engine Release works it's way down and around the piston’s rings and eventually wetting the skirt, freeing up the cylinder and making engine starting easy.

 Let the Engine Release soak in for a week.

Cover all the spark plug holes with rags to avoid having Engine Release blown out of the holes when you crank your Engine. WARNING: Keep your face away from this area when you crank it.

Now free up the gas agriculture engine by using either a pneumatic or electric impact wrench with socket on the large crank pulley nut, located on the front of the engine crank shaft.

Don't have an impact? Rent or borrow it if you have to; it's the best tool for the job!

Hammer blows from the impact wrench setup vibrations in the engine that with a help of Engine Release dislodge oxide crystals from one another freeing up the engine. Short bursts of the impact 1-2 seconds duration are all you need.

Depending on the brand, size and vintage some gas engines have what looks like a harmonic balancer mounted on the front of the crank of the engine, instead of a simple pulley.
