Draining the cooling system
When temperatures drop below freezing, failure to completely drain the cooling system will result in serious
damage to the engine and exhaust manifolds. To assure complete drainage, probe all drain openings with a
piece of wire to remove any blockage.
IMPORTANT
The following steps are very important in protecting your engine from damage in freezing conditions. If you
are unsure of how to perform any of the following steps, see your Volvo Penta dealer for a complete
end-of-season/winterization service. Freeze damage to the engine package is not covered by your Volvo
Penta limited warranty.
Perform these procedures with the boat out of the water. It will prevent damage to cooling system
components if temperatures drop below freezing.
When draining the engine, raise or lower the bow of the boat to position the engine in a level attitude. This
will provide for complete drainage of the block and manifold. If the bow of the boat is higher or lower than the
stern, some water may be trapped in the block.
Engine — fresh water cooled
1. Check the coolant level and antifreeze concentration (check antifreeze manufacturer’s instructions). Make sure
the antifreeze’s freeze point is adequate for expected temperatures.
2. Open the drain cock on the raw water side of the heat exchanger.
3. Remove the water hose clamps, hoses, and rubber caps from the exhaust manifolds.
4. After all of the water has drained out, reattach hoses/caps, tighten clamps, and replace all plugs.
Raw water pump
1. Loosen and slide clamps back.
2. Remove hoses from the rear of water pump and drain.
3. Crank the engine no more than 2 seconds (DO NOT START) to expel any water trapped in water pump.
4. Reattach water pump hoses and tighten clamps.
Oil cooler, fuel cooler, power steering cooler
Remove the lower water hose from the oil cooler. If cooler is mounted horizontally, remove either hose, loosen
mounting bolt, and tip open end of cooler down to drain.
Steering system_______________________________________________________________
The steering system is filled with an ATF oil. Change the oil whenever its color has changed to black or contains
visible impurities such as water.
1. With the engine OFF, check the oil level of the system. Note whether the
fluid is hot or cold.
2. Read the appropriate mark on the oil dipstick. If the oil level is low, an oil
leak may be present (contact your Volvo Penta dealer for repairs).
3. Check steering system hoses for cracks, leaks, and wear. Replace any
hoses that you suspect are not in optimum condition.
4. Check steering system hydraulic hoses for cracks, leaks, and wear.
Replace any hoses that you suspect are not in optimum condition.
