Volvo S90 Upper cylinder clean
Does my Volvo S90 need an upper cylinder clean?
A Volvo S90 upper cylinder/engine clean removes carbon deposits and other contaminants from the air intake and combustion chamber, without having to pull the engine apart to do so. An upper cylinder clean can improve a Volvo S90’s performance, so it runs at it’s best.
Carbon build-up, grime and contaminants are part of a Volvo S90 engine. If left to keep building up it can eventually lead to drivability issues and the engine will run rough and become less reliable. Over time this can lead to engine damage, if the Volvo S90 continues to misfire.
There are various ways to clean a Volvo S90’s upper cylinders by spraying upper cylinder cleaning into the throttle body, attaching a line to a vacuum hose to the intake manifold and/or spraying into each cylinder via the spark plug holes.
A professional automotive mechanic can carry out a Volvo S90 upper cylinder clean. They have the tools, knowledge and experience to know what cleaner is best for your Volvo S90 and the best method to get the best results.
