Figure 2.162 The heater matrix (radiator) is similar to the main radiator but smaller

folding the edges of the radiator core ends over a sealing ring and a lip on the
end-tank. Aluminium radiators are lighter and cheaper to produce than traditional
copper/brass radiators.
The water pump is usually fi tted into the water jacket of the cylinder block
( Fig. 2.163 ). However, there have been some engines where it has been fi tted
into the cylinder head. An external water pump is used on some engines and
connected to the water jacket by pipes or hoses ( Fig. 2.164 ). The water pump is
driven from the engine crankshaft by a belt.
