Volvo Engine Cold Start
NOTE! These cold start instructions are for
Volvo engines only. For other engine
makes, see the manufacturer’s handbook.
Do not use ether or similar starting aids
in a Volvo or any other engine with start
help. The Volvo engine is equipped with
a preheater. Introduction of ether or
other combustible material in the intake
manifold could cause a fire or explosion,
resulting in severe property damage, se-
vere personal injury or death.
NOTE! Volvo engines have a unique cold
start feature. Depending on the ambient
temperature, the engine cranks two to four
turns without injecting fuel. This provides
cleaner combustion at start-up and pro-
motes longer engine life.
To avoid excessive exhaust smoke when
starting a cold engine, the intake air should
be warmed up by using the preheater.
Turn the ignition key to the preheat posi-
tion and hold momentarily to engage the
preheater. It remains engaged and will light
the preheater telltale between 0 and 50 sec-
onds, depending on the engine coolant
temperature.
