Only way to tell is to look at the engine code near or on the cambelt cover. It will either end in S or S2. If it ends in S it is the 170ps version, if S2 usually the 140ps version.

They are both exactly the same 20v engine - the difference is purely in the ECU.

For some reason most 2000-2003 Volvos with SE spec say S in the logbook. No idea why.

As PD says, both the 140 and 170 bhp 2.4L engines are 20V.

The 140bhp is simply detuned via the software.

It was the 90s version of the 850/V70 that had 10v and 20v versions, they dropped this difference for the 2001 V70.

If you want to know for certain if you have 140 or 170 bhp then phone Volvo customer services, they will know.
