If just changing the belt any of the cheap tools will do - provided it is designed for your engine. If removing the sprocket you really do need the proper Volvo tool as the cheapo ones can bend - don't ask how I know😥

If using a locking tool you will need a new camshaft end cap - only one as the cam sensor fits on the other cam and can be replaced. The caps are only a couple of quid from Volvo.
