Effect
the following preliminary
checks:
a. Cleaning and replacement of air
filter
cartridge.
b.lgnition
system efficiency: spark

there is no
extra cooling fan available, keep
checking the therinometer and the
water temperature warning light on
dashboard and immediately suspend
testing if temperature’ goes up,
meaning that engine is overheating.
