ENGINE COOLING

14-2

GENERAL DESCRIPTION

M1141000100304

The cooling system is designed to keep every part of
the engine at appropriate temperature in whatever
condition the engine may be operated. The cooling
method is of the water-cooled, pressure forced circu-
lation type in which the water pump pressurizes cool-

ant and circulates it throughout the engine. If the
coolant temperature exceeds the prescribed temper-
ature, the thermostat opens to circulate the coolant
through the radiator as well so that the heat
absorbed by the coolant may be radiated into the air.
The water pump is of the centrifugal type and is
driven by the drive belt from the crankshaft. The radi-
ator is the corrugated fin, down flow type and is
cooled by the cooling fan.

ENGINE COOLING DIAGNOSIS

INTRODUCTION

M1141005300295

The system cools the engine so that it does not over-
heat and maintains the engine at an optimum tem-
perature. The system components are the radiator,
water pump, thermostat, cooling fan and fan clutch
assembly. Possible faults include low coolant, con-
tamination, belt loosening and component damage.

TROUBLESHOOTING STRATEGY

M1141005200298

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure to find
most of the engine cooling faults.
1. Gather information from the customer.

2. Verify that the condition described by the

customer exists.

3. Find the malfunction by following the Symptom

Chart.

4. Verify that the malfunction is eliminated.
