- a) On 4-cylinder engines, the regulator is attached to the line with mounting bolts;

- b) On V6 engines, an open-end wrench will be required to remove the governor.
6. Installation is carried out in the reverse order. Do not forget to replace the sealing ring, which should be lightly lubricated with clean engine oil before installation. Tighten the fasteners/regulator assembly with the required force.
