Learn How To Fix A Head Gasket With Engine Block Sealer
Occasionally, the compression in the cylinder will cause a leak to form in the gasket and the gasket will have to be replaced, or severe damage can take place (a “blown” head gasket). This problem has been exacerbated by the use of aluminum rather than iron cylinder heads; while lighter than iron, aluminum has a much greater thermal expansion rate, which in turn causes a great deal more stress to be placed on the head gasket. Engine makers have responded to this by adding a non-stick coating such as Teflon to the surface of the head gasket.
If the gasket fails, a variety of problems can occur, from compression loss (leading to power reduction, or a rough engine), to exhaust gases being forced into the cooling system, leading to the engine overheating and increased engine wear due to the motor oil being mixed with antifreeze. Coolant can leak into the cylinders, causing the exhaust to issue steam[3] and the catalytic converter to be damaged. If a very large amount of coolant does this, hydrolock can occur, causing extensive engine damage. Sometimes, all that may happen when a head gasket is blown is excessive steam erupting from the tailpipe; yet the engine may act and drive like normal, until all the coolant is gone and the engine overheats.
The following are instructions for a TEMPORARY fix for you gasket:
Drain your radiator of anti-freeze. Your block sealer won’t work correctly with the anti-freeze in the radiator. In order to do this, locate the petcock on the bottom of the radiator, open it and allow all the fluid to drain into a pan.
Dispose of the anti-freeze in accordance with EPA federal rules and regulations. A mechanic can assist you if necessary. **Anti-freeze and block sealer is a volatile mix and cannot be in the radiator at the same time.**
Prepare the sealant mixture as indicated on the product’s directions. Typically, you will need to add a specific amount of water to the mix, and then pour it into your vehicle’s radiator. Idle your vehicle for about 30 minutes to let it settle in the cracks.
Do some driving to make sure the mixture moves around and fills in all the cracks. Drive the vehicle a day for the treatment to fully dry.
Drain the sealer and add new anti-freeze.
Get a new radiator or head gasket in your vehicle once you can afford the time and money for the repairs.
Purchase a new radiator or head gasket as soon as you can afford to complete repairs.
