Note:
1. It is very important that the liquid gaskets listed above or their exact equivalent is used on the vehicle.
2. Be careful to use the specified amount of liquid gasket.
Follow the manufacturer'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 LOCTIT E 518 between tw o metal surfaces having a clearance of greater than
0.25 mm (0.01 in). Poor adhesion will result.
