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.
The cast iron block 16 valve 4 cylinder had a spec of 4 but no unit was listed since the tool was provided by Volvo and it had no units on its face, just the numbers.

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

S60 Timing Belt Marks

And the barely visible timing marks on the crankshaft gear and engine block – the one on the engine block it’s not visible with the belt on, but can be felt by hand, it’s a small bump. There is also a timing bump on the crankshaft pulley (not visible in the photo).

S70 – Replace Water Pump

Perhaps this may be obvious to the seasoned DIY’er’s or even some regular guys like me but after mulling it over and with the help of a couple of links I decided to tackle the Water Pump replacement by removing only the Hydraulic Tensioner. There were many other excellent links in the various Volvo forums (this one included) that some may find to be more helpful but the following provided me with the larger picture of what I needed to do.
