Cooling System - New Holland 6010 Service Manual

Engine - Engine and crankcase
An intermittent flow of oil is directed to the value rocker arm shaft assembly via a drilled passage in the cylinder block.
This is located vertically above No. 3 camshaft bearing and aligns to a hole in the cylinder head. The rotation of the
camshaft allows a controlled intermediate flow of lubrication.

COOLING SYSTEM

The function of the water pump mounted at the front of the engine, is to maintain a continuous flow of water around
the cooling system. This is essential to ensure engine temperature and performance within the recommended range,
during vehicle operation.
The Water pump is driven by a 'V' belt by the crankshaft pulley, when the engine is running.
The cooling system for the new generation of engines is of recirculating by‐pass type with full length water jackets for
the bottom tank of the radiator by the water pump, which passes the coolant to the cylinder block. This coolant then
flows through cored passages to cool the cylinder walls.
Passages in the cylinder head gasket allow coolant to flow from the cylinder block, into the cylinder head cored pas-
sages also conduct the coolant to the fuel injector nozzle locations before re‐entering the water pump below the
thermostat
The thermostat is located in the top of the water pump body, and controls the flow of the water as required by tem-
perature changes.
