Coolant - composit ion -guarantee
Since aluminium is used in the engines, active corrosion
protection
is necessary in the coolant to help prevent corro
sion damage.
Use genuine
Volvo coolant, type C (blu e-green), diluted
with clea n water in proportions of SO/50. This mixture helps
to prevent corrosion and frost damage.
• Never top-up the cooling system with water alone. Use
genuine
Volvo coolant diluted with clean water in propor
tions of 50/50.
•
The coolant should be changed every 40,000 km
(25,000 miles) since the corrosion-protective additives in
the coolant lose their effect in time.
• The cooling system should be cleaned using solvent
PIN 1 161 328-8 prior to filling new coolant.

RON stands for Resea rch Octane Number, and is a measure of
the ability of a fuel to withstand knocking. MON stands for Motor Octane Number and is another way of
measuring the same property.
(R+M)/2,
also called AKI (Anti Knock Index) combines these two
m eas urem ents .
95
RON is equivalent to 91 (R+M)/2. 91 RON i s equivalent to 87 (R+M) /2.

Valves
IMPORTANT: Exhaust valves are stellite-flashed and must not
be machined . They may only be ground in against seat.
Min:
8200/ 230 = 7,935 8204/234 = 6 ,95
IMPORTANT : Scrapping exhaust valves. The exhaust valves on turbo engines are sodium filled and must not be mixed with
ordinary scrap iron before first removing the sodium.

Note:
The force used when pressing in valve guides must be at least 9000 N (1980 Ib). If the pressing force used is lower then
the recess for the guide must be reamed out to the nearest
oversize and a guide
of the corresponding size pressed in.
