Note :
1. It is very important that the liquid gaskets listed above or their exact equivalent be used on the vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacture's instructions at all times.
3. Be absolutely sure to remove all lubricants and moisture from the connecting surfaces before applying
the liquid gasket.
The connecting surfaces must be perfectly dry.
4. LOCTITE 515 and LOCTITE 518 harden upon contact with a metal surface.
Do not apply LOCTITE 515 or LOCTITE 518 between two metal surfaces having a clearance of greater
than 0.25 mm (0.01 in). Poor adhesion will result.
RECOMMENDED THREAD LOCKING AGENTS

LOCTITE 242 Blue1. Completely remove all lubricant and moisture from the bolts and
the female threaded surfaces of the parts to be joined.
The surfaces must be perfectly dry.
