Check coolant level

The cooling system must be filled with coolant and not leak to operate a\
t maximum efficiency. Check
the coolant level whenever you refuel. The level should be between the "\
Max"' and "Min" marks on the
expansion tank. The check should be made with particular thoroughness wh\
en the engine is new or the
cooling system has been drained.
Do not remove the filler cap other than for topping up with coolant. Fre\
quent removal may prevent
coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
CAUTION
The cooling system must always be kept filled to the correct level.
If it is not kept filled, there can be high local temperatures in the en\
gine which could result in
damage.

Top up with coolant

Top up with coolant by filling the expansion tank when level is at the "\
Min" mark. Use a mixture of 50
percent Volvo Type C coolant and 50 percent water all the year round. To\
p up to the "Max" mark.
If the engine is warm, and you are going to add coolant, unscrew the cap\
slowly in order to allow any
excess pressure to escape.
Note: Do not add 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 c\
ooling system if it should
freeze.
See 'Specifications' section of the manual for type of coolant recommend\
ed.

Cooling system

The risk of overheating is greatest, especially in hot weather, when:
- towing a trailer up steep inclines for prolonged periods at full throt\
tle, and at low engine rpm.
- idling for prolonged periods while the air conditioning system is in o\
peration.
- stopping the engine suddenly after high speed driving, so called after\
-boiling.
To avoid overheating. the following rules should be followed.
l Reduce speed and downshift when towing a trailer up long steep inclines.\
The risk of over heating can
be reduced by switching off the air conditioning system for a short whil\
e.
l Do not let the engine idle unnecessarily.
l Do not stop the engine immediately after high-speed driving, but allow t\
he engine to idle for 1/2 - 1
minute before switching off.
When the risk of overheating is imminent, or in the event of overheating\
, (the temperature gauge goes
repeatedly into, or stays continually in, the red section) the followin\
g precautions should be taken:
l Switch off the air conditioning system and switch the heater to full (m\
aximum) position.
l Stop the car and put the gear lever into neutral position-position N. Do\
not stop the engine!
l Increase the engine speed to approx. 2000 rpm (twice idling speed).
l Check the level of coolant in the expansion tank. Top-up, if necessary

Electrical System cautions

When changing the battery or when carrying out work involving the electr\
ical system, the following
should be observed:

1 A battery connection to the wrong terminal will damage the diodes. Bef\
ore connections are made,
check the polarity of the battery with a voltmeter.

2 If booster batteries are used for starting, they must be properly conn\
ected to prevent the diodes from
being damaged. For correct connection, see "Jump starting".

3 The battery leads should be disconnected any time the battery is being\
charged.

Prior to a long distance trip

Have your car checked at a Volvo dealer. Preventive maintenance will hel\
p to ensure a trouble free trip.
Remember to take along a Volvo dealer directory.
The main items to check are listed below:
1. Brakes, front wheel alignment and steering gear.
2. Engine running condition.
3. Fuel system operation.
4. Oil leaks: engine, transmission, rear axle.
5. Cooling system for leaks or worn hoses.
6. Examine tires carefully, replace worn tires.
7. Battery and terminals.
8. Tool equipment.
9. Lighting.
10. Drive belts, for tightness and wear.
11. All fluid levels.

Cold weather/Engine fuel system

During the winter, large variations in temperature cause condensation to\
form in the fuel tank and can
impair the running of the engine. This can be reduced by adding dry gas \
to the fuel. There is less risk of
condensation forming in the fuel tank if it is kept full or nearly full.\


Engine cooling system

Volvo type C (blue-green) coolant should be used all year round. The c\
ooling system should always
contain water plus anti-freeze and rust inhibitor, even during the summe\
r. Experience has also shown
that extremely weak anti-freeze solutions (10-25 percent) are ineffect\
ive for rust protection. For this
reason, the quantity of antifreeze/summer coolant should be about 50 per\
cent of the solution. This
lowers the freezing point to - 30 ° F (-35 ° C).
