both the anti-freeze and cooling
properties will decrease, affecting the engine adve rsely. For these reasons, be sure to maintain
the concentration level within the specified range.
2. Do not use a mixture of different brands of anti -freeze.

2.For non-turbo, remove the ‘drain plug from
block to drain engine coolant.
For turbo, remove the water hose from the water pip e
assembly (C) to do so.

5.Remove the reserve tank to drain the coolant.
When the engine coolant has drained, pour in water from
the cap to clean the engine coolant line.
For non-turbo, install the drain plug to the cylind er block.
For turbo, install the water hose to pipe assembly

Securely tighten the radiator drain plug.
Install the reserve tank.
9.
Slowly pour the engine coolant into the mouth of th e
radiator until the radiator is full, and pour also into the
reserve tank up to the FULL line.
Recommended antifreeze:
LONG-LIFE COOLANT (Part No. 0103044)
or high quality ethylene-glycol antifreeze coolant)
Quantity 7.0

Install the cap securely.
Start the engine and warm the engine until the the rmostat
opens. (Touch the radiator hose with your hand to c heck
that warm water is flowing.)
11. After the thermostat opens, race the engine at 3,000
3 times.
12. After the engine is stopped, wait until the eng ine has
cooled down, and then remove the cap to check the
level of the liquid. If the level is low, repeat th e operation
from step 9.
Lastly, if the level does not drop, fill the conden se tank
with coolant up to the FULL line.
15. DISC BRAKE PADS (Check for wear)
Check for fluid contamination and wear. Replace com plete
set of pads if defective.
Caution
The pads for the right and left wheels should be re placed
at, the same time. Never “split” or intermix brake pad
sets.
All four pads must be replaced as a complete set.

Also see if the gears are in proper mesh with each other.
To assure smooth operation, apply a thin coat of
multipurpose grease to the friction surface of adju ster

LASH CHECK
A tappet-like may be produced from several items.
Check the following items. 1. Engine oil level too high or too low.
This may cause, aerated oil to enter, the adjusters and
cause them to be spongy.
2.Insufficient running time after rebuilding the cyli nder head.
Low speed running up to 1 hour may be required.
3. Low oil pressure.
4. The oil restrictor pressed in to the vertical oi l passage
to the cylinder head is plugged with debris.
5.Air ingested in to oil due to broken or cracked oil pump
pick up.
6. Worn valve guide.
7. Faulty hydraulic lash adjuster. (1) Check for sponginess while still installed in e ngine.
Depress part of the cam follower just over the adju ster.
Normal adjusters should be free and very firm.
Spongy adjusters can be depressed to the bottomed
position easily.
(2) Remove a suspected hydraulic lash adjuster asse m-
bly.
(3) Clean out dirt and varnish with solvent.
(4) Reassemble with engine oil.
(5) Check for sponginess.
(6) If still spongy, replace
new adjuster
assembly. .
