High-Strength Steel
HIGH-STRENGTH STEEL (HSS) PARTS
Generally, High-Strength Steel (HSS) is that which has an intensity value of at 35 kgf/mm2
(343 MPa),
and distinguished from mild steel.
The handling of HSS is the same as for mild steel, but the following should be observed.
1. Panel Hammering: Because HSS is thinner than mild steel, care should be taken to avoid warping
during hammering operations.
2. Removing Spot Welds: Because HSS is tougher than mild steel, damage will occur more easily to
a regular drill. Therefore, an HSS Spot Cutter is recommended.
Also, use a high-torque drill at low speed, and supply grinding oil to the drill during use.
3. Panel Welding: Panel welding procedures for HSS are exactly the same as for mild steel. Plug
welding should be done with MIG (Metal Inert Gas) welder. Do not gas weld or braze panels at
areas other than specified.

REPLACEMENT
1. DRAIN ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
(b) Loosen the 2 drain plugs (for the engine and radiator),
and drain the coolant.
HINT:
To prevent the coolant from spraying over the cylinder block,
connect the rubber hose (inside diameter 6 - 8 mm) in the mar-
ket to the union pipe under.
(c) Close the drain plugs.
Torque:

29 N´m (300 kgf´cm, 22 ft´lbf)
2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.

Use a good brand of ethylene-glycol base coolant
and mix it according to the manufacturer's direc-
tions.

Using coolant which includes more than 50 % ethyl-
ene-glycol (but not more than 70 %) is recom-
mended.
NOTICE:

Do not use an alcohol type coolant.

The coolant should be mixed with demineralized wa-
ter or distilled water.

REASSEMBLY
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the O-ring contact surface of the lower tank and oil
cooler.
(b) Install new O-rings (1) to the oil cooler (2).
(c) Install the oil cooler (2) to the lower tank (3).
(d) Install the plate washers (4), and nuts (5).
Torque: 8.3 N´m (85 kgf´cm, 74 in.´lbf)
(e) Install the inlet pipes (6).
Torque: 15 N´m (150 kgf´cm, 11 ft´lbf)
HINT:
Face the inlet pipes in the same direction they were before dis-
assembly.
2. INSPECT LOCK PLATE
Inspect the lock plate for damage.
HINT:

If the sides of the lock plate groove are deformed, reas-
sembly of the tank will be impossible.

Therefore, first correct any deformation with pliers or simi-
lar object. Water leakage will result if the bottom of the
lock plate groove is damaged or dented. Therefore, repair
or replace if necessary.
NOTICE:
The radiator can only be recaulked 2 times.
After the 2nd time, the radiator core must be replaced.
3. INSTALL NEW O-RINGS AND TANKS
(a) After checking that there are no foreign objects in the lock
plate groove, install the new O-ring without twisting it.
HINT:
When cleaning the lock plate groove, lightly rub it with sand pa-
per without scratching it.
(b) Install the tank without damaging the O-ring.
(c) Tap the lock plate with a soft-faced hammer so that there
is no gap between it and the tank.
