DESCRIPTION & OPERATION
Page 53
A 2-1/4-inch diameter steel coolant tube connects
the oil cooler water outlet to the water pump inlet.
The tube connects to the water pump with a
flange, and a gasket is used at the joint between
the water pump and tube flange. On earlier
engines, the coolant tube connects to the oil
cooler water outlet by an O-ring connection. On
later engines, the O-ring connection was replaced
by a hose connection. The most commonly used
tube has two smaller tubes attached to the main
tube (one tube for the thermostat bypass and the
other for the water line to the surge tank). Other
chassis models use variations of this tube
assembly.
