Topic: Guess the Breakdown!
My semi-truck has a noise. It is a Volvo 780, with a D16 engine.
The noise is a hissing sound behind the fan, centered near the fan.
No it's not the fan, I think, no the belt... it is intact and no wear. It does not happen with key in start position, only when the truck is running.
I did have low oil, but filled it and should not, hopefully be the problem.
I will of course have an idea in the next hour or two, but I figured this could be a good guessing game for the mechanically inclined ![]()

Avogardo and Noir ignored by me for life so people know why I do not respond to them. (Informational)
