Re: Yanmar YQM15 - hard starting
Is there any harm to spraying a little "Heet" fluid into the air intake of a Yanmar 3GM30F diesel for cold starts? Its taking longer and longer, 20-30 secs of total cranking spread over two attempts to start it in the cool damp winter of the Pacific NW. I am worried about raw water getting sucked into the engine with all this cranking, not to mention the stress on the starter and batteries. However, one quick spritz of HEET into the air intake and the thing starts on first crank (1-2 secs max). Its a miracle drug as far as I can tell. My only concern is , is it bad for the engine in any way to use this spray ?
