If the engine is warm, and you are going to top up coolant, unscrew the cap slowly in order to allow any excess pressure to escape. Note: Do not top up with water only. Water by itself reduces the rust-protective and anti-freeze qualities of the coolant and has a lower boiling point. It can also cause damage to the cooling system if it should freeze.
pg. 60 Replacing bulbs Note: This car is equipped with an alternator. When changing the battery or when carrying out work involving the electrical system, the following should be observed: 1 A battery connection to the wrong terminal will damage the diodes. Before connections are made, check the polarity of the battery with a voltmeter. 2 If booster batteries are used for starting, they must be properly connected to prevent the diodes from being damaged. The ground lead from the booster battery must be connected to the ground terminal of the car battery and the positive lead from the booster battery to the positive terminal. 3 If a fast charger is used for charging the battery, the battery leads should be disconnected. 4 Never disconnect the battery circuit (for example, to change the battery) while the engine is running, as this will immediately ruin the alternator. Always make sure that all the battery connections are properly tightened. 5 If any electrical welding work is made on the vehicle, the ground lead and all the connecting cables of the alternator must be disconnected and the welder wires placed as near the welding point as possible. Replacing bulbs The replacement of bulbs in the various lighting units is shown on the following pages. Make sure when installing bulbs, that the guide pin on the socket fits into its corresponding recess. When installing bulbs, do not touch the glass with your fingers. The reason for this is that grease, oil or any other impurities can be carbonized onto the bulb and damage the reflector. Replacing bulbs for instrument lighting and heater control lighting Due to the location of the bulbs, their replacement should be carried out by a Volvo dealer. Replacing bulbs for side marker lights Remove the two Phillips screws which hold the lens. The bulb can now be removed by pressing it inwards and turning it slightly counterclockwise.
