(6) Coolant level
The level of coolant in the surge tank should be
maintained between "MIN" and "MAX" marks.
When the coolant level is found to be lower than
"MIN" mark, check the cooling system for leaks,
and then top it up to the "MAX" mark.
Caution
1. Do not remove the coolant surge tank cap when
the engine and radiator are hot. Scalding hot
coolant and steam may be blown out under
pressure, which could cause serious injuries.
2. Replenishing the surge tank with cold water
abruptly when coolant is hot may affect adversely
the cylinder block or cylinder head. Therefore,
allow a few minutes for the coolant to cool down
before replenishing.
(7) Fan belt tension
Loose belt can adversely affect the alternator
charging system and cause engine overheat-
ing or premature wear to the belt. On the other
hand, A fan belt which is too tight can cause
premature damage to the bearings of its periph-
eral devices. Follow these procedures to adjust
the fan belt tension:
1. 1 DE Engine: First, loosen the air-con com-
pressor bolt, then adjust the belt tension
by turning the nuts fit to the adjust bolts.
2 DV Engine: Loosen the nut fit to the idle
pulley, then adjust the belt tension by
turning the nuts fit to the adjust bolts.
2. The tension of the belt must be such that
there is a deflection of 10~15mm when the
midpoints between air-con compressor pul-
ley and crankshaft pulley, between crank-
shaft pulley and alternator pulley, and be-
tween crankshaft pulley and fan clutch pul-
ley are depressed with force of about 10kg.
In the event of DDC engine, adjust the belt
tension so that a firm push with the thumb,
at a point midway between crankshaft pul-
ley and fan pulley, will depress the belt
12~19mm.
3. The belts should be replaced as a set even
when either of them is found defective.
(8) Break fluid level
Check break fluid level in the reservoir and top
up as necessary.
