Q: No compression in engine

asked by on

My engine has no compression. What could be causing this?

Unfortunately there are a few reasons as to why your Volvo’s engine has no compression. The most common reason I have experienced would be when the timing belt fails. When this belt fails, the starter will crank the engine over, which moves the pistons, but because the timing belt has failed the camshafts may not move at all. To be 100% certain this is the problem, it may be time to enlist the assistance of a certified mechanic. They will have the knowledge and tools needed to identify exactly why your S40 has no compression and assist you on making the necessary repairs, such as replacing your timing belt, to get your Volvo running again.
