3. ENGINE COMPARTMENT LAYOUT
Do not work on the engine compartment while the engine, radiator, exhaust manifold, muffler
or catalytic converter is hot. Always turn the engine off and allow it to cool before starting the
maintenance.
Regularly check the engine oil level and add Ssangyong genuine engine oil if necessary.
Clean the dipstick with clean cloth so that any foreign materials cannot get into the engine. -

A. Overview of cooling fan and A/C compressor
The cooling system maintains the engine temperature at an efficient level during all engine
operating conditions. The water pump draws the coolant from the radiator. The coolant then
circulates through water jackets in the engine block, the intake manifold, and the cylinder head.
When the coolant reaches the operating temperature of the thermostat, the thermostat opens.
The coolant then goes back to the radiator where it cools. The heat from automatic transmission
is also cooled down through the radiator by circulating the oil through the oil pump. ECU controls
the electric cooling fans with three cooling fan relays to improve the engine torque and air
conditioning performance.
For detailed information, refer to Chapter "Air Conditioning System".

A. Overview
The supplementary electrical heater is installed in DI engine equipped vehicle as a basic
equipment. The PTC system is operated according to two temperature values measured at the
coolant temperature sensor and HFM sensor. This device is mounted in the heater air outlet and
increase the temperature of air to the passenger compartment. Because PTC system is heated by
electrical power, high capacity alternator is required. PTC does not operate during engine
cranking, while the battery voltage is lower than 11 V or during preheating process of glow plugs.

C. Operation process
The ceramic PTC has a feature that the resistance goes up very high at a certain temperature.
There are three circuits in PTC heater. Only one circuit is connected when PTC1 relay is ON, and
two circuits are connected when PTC2 relay is ON.
