Maintenance And Care; Engine - Volvo Penta 3.0GS/SX Owner's Manual

Maintenance and Care

Volvo Penta engines and transmissions are designed for maximum service life and reliability. They are built to
survive in a tough marine environment, but also to cause as little environmental impact as possible. In order for
your engine and transmission to operate reliably, regular maintenance is necessary. This chapter describes the
engine/transmission and how to carry out the most essential maintenance operations. The following chapter has
a maintenance schedule which shows when maintenance operations must be carried out.
NOTE! Always use Volvo Penta Original Spare Parts, otherwise you run the risk of losing the original quality of
the product, quite literally bit by bit.
WARNING! To prevent personal injury the engine must be turned off before starting maintenance work.

Belt adjustments. General
WARNING! Ensure that the ignition is off and the
ignition key out before inspecting and tightening
belts.
NOTE! The belts used for the alternator, water
supply pump, and power steering pump are heavy
duty. Do not replace with automotive belts.
Check the tension and condition of the belts regularly.
A belt that is too tight can damage the bearings and a
belt that is too loose can result in slippage and poor
charging, coolant water flow and power steering.
Inspect and adjust after running the engine so that the
belts are warm. Replace belts if they seem worn or
are cracked.
The correct belt tension has been achieved when the
belt can be pressed down 6 – 13 mm with normal
thumb pressure, approx. 300 N at points A, B and C.
