# Service bulletin MI26\-00

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

The gasket thickness was increased from 1.5 mm to 3 mm to prevent interference between the collar ends, which previously made it impossible to reach the specified tightening torque. Increasing the gasket thickness ensures sufficient clearance between the collar ends and thus guarantees optimal tightening.
