COLD WEATHER OPERATION
Volvo Engine Cold Start
Note: These cold start instructions are for Volvo engines only. For other engine makes,
see the manufacturer’s handbook.
DANGER
DO NOT use ether or other combustible
starting aids on any Volvo engine.
Introduction of ether or similar starting
aids could cause a fire or explosion
resulting in severe property damage,
serious 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 promotes longer engine life.
When starting a cold engine, the intake air should be warmed up by using the preheater. Turn
the ignition key to the drive position and push the key in to request preheater engagement.
The preheater does not engage at coolant temperatures above 12
C (54 F). If the coolant
temperature is below 12
C (54 F), the preheater will engage and will light the preheater
tell-tale between 0 and 50 seconds, depending on the engine coolant temperature.
