NOTE:
An
antifreeze concentration should be selected on the basis of a temperature which
is about 10 0 F (50 C) lower than the actual atmospheric temperature expected.
B. Filling the Fresh Water System
A coolant recovery tank kit:, PN
0249n,
is supplied with each Westerbeke gasoline generator. The purpose
of this recovery tank is to allow for engine coolant expansion and contraction, during engine operation,
without the loss of coolant and without introducing air into the cooling system.
This coolant recovery tank should be installed at, or above, the engine's manifold level, in a location where
it can be easDy monitored and where coolant can be easDyadded,
if
needed (see the figure below). A stainless
steel mounting bracket
is
supplied with each kit along with a 30 inch length of clear plastic hose and clamps
to connect the hose between the engine's manifold fitting to the hose spud on the base of the recovery tank.
Coolant Recovery Tank, Recommended Installation
NOTE: Coolant loss can occur at the connection points of the plastic hose, at the manifold
fitting, and the tank spud and go undetected when this coolant leaks onto the hot exhaust
manifold and evaporates. Check these connections when troubleshooting the cooling system
for coolant loss.
