ENGINE MAINTENANCE

MA-13prose procedure

1
Inspect for cracks, fraying, wear or oil adhesion. If necessary, replace with a new one.
2
Inspect drive belt deflections by pushing on the belt midway between pulleys.
SMA989B

IMPORTANT

Adjust if belt deflections exceed the limit.

NOTE

Inspect drive belt deflections when engine is cold.

Changing Engine Coolant

WARNING

WARNING: To avoid being scalded, never change the coolant when the engine is hot.

1
Move heater "TEMP" control lever all the way to "HOT" position.
SMA990B
2
Open drain cock at the bottom of radiator, and remove radiator cap.
Be careful not to allow coolant to contact drive belts.
SMA991B
3
Remove cylinder block drain plug.
SLC764
4
Close drain cock and tighten drain plug securely.
5
Fill radiator with water and warm up engine.
6
Stop engine and wait until it cools down.
7
Repeat step 2 through step 6 until clear water begins to drain from radiator.
8
Drain water.
Apply sealant to the thread of drain plug. Torque: 54 - 74 N·m (5.5 - 7.5 kg-m, 40 - 54 ft-lb)
