2. When disconnecting vacuum hoses, use tags to identify where they should be reconnected.
3. After completing any hose related repairs, double check that the vacuum hoses are properly connected. The label under the hood shows the proper layout.
4. When using a vacuum gauge, never force the hose onto a connector that is too large. If a hose has been stretched, air may leak. Use a step-down adapter if necessary.

Use the formula below to calculate special torque values for situations where SST or an extension tool is combined with the torque wrench.

Formula: T' = L2/(L1 + L2) * T

TORQUE WRENCH REFERENCE

T'	Reading of torque wrench {Nm (kgfcm, ft.*lbf)}
T	Torque {Nm (kgfcm, ft.*lbf)}
L1	Length of SST or extension tool {cm (In.)}
L2	Length of torque wrench {cm (In.)}
