ENGINE COOLING
NOTE: Antifreeze solution + Water = Total cooling
system capacity.

A/T 8.4Lit (2.22Us gal)
B06RW002
Mixing ratio
Check the specific gravity of engine coolant in the
cooling system temperature ranges from 0
C to 50C
using a suction type hydrometer, then determine the
density of the engine coolant by referring to the table.
NOTE:
1. Even in the areas where the atmospheric
temperature is higher than 0
C, be sure not to use
antifreeze solution at a mixing ratio lower than 20% so
that the inside of the engine may not be corroded.
2. If antifreeze solution is used at a mixing ratio higher
than 60%, the specific heat of the coolant falls and the
engine may be overheated. Moreover, antifreeze
performance drop and the coolant may be frozen.
The density of the solution must be adjusted as
occasion calls.
Antifreeze solution lower than 20% may not have
sufficient anticorrosive performance, and therefore,
please never fail to adjust as occasion demands within
the range of 20% to 60%.

The drive belt adjustment is not required as automatic

Inspection
Check drive belt for wear or damage, and replace with a
new one as necessary.
Installation
Install cooling fan assembly and tighten bolts/nuts to the
specified torque.
Torque : 22 Nꞏm (2.2 Kgꞏm/16 lb ft) for fan pulley
and fan bracket.
Torque : 10 Nꞏm (1.0 Kgꞏm/88.5 lb in) for fan and
clutch assembly.
NOTE: Fan belts for 6VE1 Gasoline Engine mounted on
98MY (UX) have been brought into one. As a result, the
rotating direction of a fan belt is opposite to the direction
o f c o o l i n g f a n f o r 9 2 t o 9 7 M Y 6 V D 1 w i t h n o
interchangeability.
Therefore, incorrect installation of a fan may cause the air
for cooling to flow in the opposite direction, this resulting
in the poor performance of the air-conditioner and a rise
temperature in engine cooling water.

and camshaft carrier.
5. Camshaft thrust clearance.
1) Clean the camshaft, camshaft bracket and
camshaft carrier.
2) Put camshaft carrier on the cylinder head.
3) Put camshaft on the camshaft carrier.
4) Put plastigauge on the camshaft journal.5) Install camshaft bracket to original position and
tighten bolts to specified torque in the numerical
order shown in the illustration.
Torque: A; 21.6 Nꞏm (2.2 kgꞏm/15.9 lb ft)
B; 38.0 Nꞏm (3.9 kgꞏm/28.2 lb ft)

D; 38.0 Nꞏm (3.9 kgꞏm/28.2 lb ft)
6) Use a dial indicator to measure the camshaft
thrust clearance. If the camshaft thrust
clearance exceeds the specified limit, replace
the camshaft carrier and/or camshaft.
Camshaft thrust clearance
Standard: 0.1 mm (0.0002 in)
Limit: 0.2 mm (0.0078 in)
