– Different types of Volvo Penta coolant must not be mixed with each other. – Risk of reduced cooling function and performance by clogging and isolation.. – Follow the mixing recommendation on the product. – The coolant should be mixed with distilled, deionized water. For Volvo Penta specified water requirements. # NOTICE:   Always use “Ready Mixed” coolant if water quality cannot be determined or if it does not fulfill ASTM D4985.   Never mix more than 60% concentrated coolant with water (Its not good for volvo penta closed cooling system)

1) Coolant Level, Checking and Topping up.  # NOTICE:   – Do not open the coolant filler cap when the engine is hot, except in emergencies as this could cause serious personal injury. Steam or hot fluid could spray out   – Only use coolant recommended by Volvo Penta. Fill up with the same type of coolant that is in the system. Different types of coolant must not be mixed with each other   – Filling of coolant must be performed with the engine stopped. Fill up slowly, to allow the air to flow out. Check the coolant level daily before start.  # Carry out:   – TWD16:    1- Open the filler caps (1).    2- Check that the coolant reaches the MAX mark on the sight glass (2). Top up with coolant as required    3- Close the filler caps.  – TAD16:    1- Open only the filler cap (1). Do not open the pressure cap (2).    2- Check that the coolant level is between the MIN and MAX marks on the expansion tank (1). Top up with coolant as required    3- Close the filler cap.

2) Filling a completely empty system.  – Mix the correct amount of coolant in advance, to ensure that the cooling system is completely filled. Refer to Technical Data, page 91 for the correct coolant volume.  – Do not start the engine until the cooling system is completely filled and vented.  – If a heating unit is connected to the engine cooling system, the heating control valve should be opened and the installation vented during filling.  – Carry out topping up in the cooling system:   1- Check all drain points closed.   2- TWD16:      Open the caps to both the expansion tank (1) and the radiator (2). Fill the expansion tank so that the coolant reaches the MAX mark on the sight glass. Close the filler caps.     TAD16      Open only the filler cap (1). Fill the expansion tank so that the coolant level is between the MIN and MAX marks. Close the filler cap.    3- Bleed the system at the bleeding nipple (3).   4- Start the engine when the coolant system completely filled and vented. Open any bleeding nipples a short while after starting, to allow trapped air to escape.   ….
