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.

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.

DIY: 1998 Volvo S70 Timing Belt Overhaul

The TB (Timing Belt) with 85K on it is still OK, has hairline cracks, but time to replace.
The TB factory Idler and Tensioner Pulleys have slight play and were “free-wheeling”, so time to replace
The WP has no leak, but the bearing has a very very slight play. Technically speaking, you can keep the WP for another 30K. From reading Ozark Lee’s and few others experience with leaking WP at 150K or so, and since I have no time to redo this in 30K, I put in a new Aisin WP.

Timing Belt Photos

Whether you’re planning to replace your Volvo’s timing belt, have someone else replace it, or just want to know what the terms mean, I’ve got your timing belt photos here. Sent in by MVS user Carl, they’re technically good photos, very large, and each photo is captioned.

Head Gasket Change Parts List

You want to do the valve seals while you’re at it. This is not an overkill because they are probably nearing the end of their life cycle and will develop oil seepage (just to make you feel regretful one day that you have to redo the gasket).
On another note, have you ever overheated the engine? Even if you haven’t, the mating surfaces for the head gasket need to be planed. There is usually a reason for the gasket to fail (and not always an apparent one).
