Timing Belt Tension Specification on a 1998 Volvo

Volvo does not publish belt tension specs for “white” engines. The hydraulic tensioner took care of it and then the eccentric tensioners have the goalposts as marker for the correct tension range with engine cold.

I worked for the manufacturer when that car was new and there was no information in any of the published info for technical personnel.

– Upper Rad Hose PN 1335433, about $15 at dealer.
