1 Check has to be made at the cold engine therefore it is better to be engaged in it before a trip, the first for the present day, or not earlier than in three hours after switching off of the engine. Check a state twist systems of release, beginning from the engine and finishing with a cut of an exhaust pipe.

If the winch is inaccessible, the car and reliably install to a poddomkratta it on support.
