GLOSSARY OF TERMS
Introduction
This glossary of terms is intended to cover both general and emissions-related (to SAE J 1930) terminology. It is in- tended to enable the user to ascertain the meaning of standardized terms and acronyms used throughout the Manual.
The required term may be looked-up in the left-hand column, and subsequent columns give the standard abbreviation
or acronym, definitions and previously used terms, as applicable.
As this Manual is a world
-wide publication, and must comply with certain Society of Automotive Engineers Standards, it has been necessary to adopt the terminology etc. demanded by that Standard.

Cooling System (AJl6) m
4.1.1 COOLING SYSTEM DESCRIPTION
4.1.1.1 Major Components
o Main engine crossflow radiator, incorporating a concentric tube cooler for the power steering fluid mounted in
the right
-hand radiator side tank. Vehicles with automatic transmission have a transmission fluid cooler
mounted in the left
-hand radiator side tank; for 4,O liter supercharged engines a six-plate cooler is fitted; other
vehicles have
a tube-type cooler. Adouble-action temperature switch, for controlling the radiator cooling fans,
is mounted in the left
-hand radiator side tank.
0 Two electrically operated radiator cooling fans, mounted behind the main radiator.
0 Coolant circulating pump, belt driven from the engine crankshaft.
0 Coolant header tank with pressure relief cap and coolant level probe.
o Engine thermostat.
4.1.1.2
0 Heater matrix.
o Electrically operated coolant circulating pump, mounted on the left-hand side of the engine bulkhead.
o Solenoid operated valve, located adjacent to the coolant circulating pump.
Components for Climate Control System
4.1.1.3 Components for Supercharged Engine
0 0 Supercharger crossflow radiator, mounted in front of the main radiator. The supercharger radiator is reverse- circuited, i.e. the coolant inlet is at the bottom of the radiator.
0 Electrically operated coolant circulating pump, located at the left-hand side of the main radiator.
4.1.1.4 Operation
The configuration of the cooling system for normally aspirated and supercharged (4,O liter) engines is shown in Sub- section 4.1.2.
The cooling system is pressurized, which allows the system to operate at a higher temperature without overheating.
The header tank is fitted with a pressure relief cap to protect the system against overpressure.
Under cold start conditions, coolant is forced by the engine driven water pump through the cylinder block and cylinder
head to the thermostat housing. The thermostat is closed to give rapid engine warm up, hence the coolant is returned
directly to the water pump inlet. When normal engine operating temperature is reached, the thermostat opens and
coolant is diverted through the radiator before returning to the water pump inlet. In vehicles fitted with
a supercharger,
coolant is circulated through the supercharger radiator and intercooler by the supercharger water pump. The super- charger cooling circuit uses the same coolant header tank as the main engine cooling system.
The radiator cooling fans operate in series and parallel under the control of the double
-action radiator mounted tem- perature switch. The fans are also controlled by the climate control system on vehicles fitted with air conditioning.
Under hot operating conditions, the fans may continue to operate after the engine has been switched off. The fans
stop automatically when the coolant temperature has been reduced sufficiently.
The system also provides the coolant supply for the climate control system, which is described in Section
14.

mounted in the right

radiator cooling fans, is mounted in the left

0 Engine driven, viscous-coupled, radiator cooling fan
0 Two electrically operated radiator cooling fans, mounted in front of the radiator.
o Coolant circulating pump, belt driven from the engine crankshaft.
0 Coolant header tank with pressure relief cap and coolant level probe.
0 Two engine thermostats, one in each cylinder bank.

4.2.1.3 Operation
The configuration of the cooling system is shown in Sub-section 4.2.2.
The cooling system is pressurized, which allows the system to operate at a higher temperature without overheating.
The header tank is fitted with a pressure relief cap to protect the system against overpressure.
Under cold start conditions, coolant is forced by the engine driven water pump through each cylinder block and cylin
- der head to the thermostat housings. The thermostats are closed to give rapid engine warm up, hence the coolant is
returned via the engine cross pipe to the water pump inlet. When normal engine operating temperature is reached,
the thermostats open and coolant is diverted through the radiator before returning to the water pump inlet.
If the engine driven fan is unable to provide sufficient cooling, the electrically operated fans operate in series and paral
-
lel underthe control of the radiator mounted temperature switch. Under hot operating conditions, the electric fans may
continue to operate after the engine has been switched off. The fans stop automatically when the coolant temperature
has been reduced sufficiently.
The system also provides the coolant supply for the climate control system, which is described in Section 14.
