I recently purchased a 2006 XC 70 with 114,000 miles I dont have service records. I am proactively changing the timing belt and water pump . In ordering a timing belt site I found the following: for 2006 Volvo XC 70 engine number 3188688, the Aisin timing belt kit is AIS TKV001; for engine number 3188689, the timing belt set is AIS TKV003. Howver, when I checked my engine number, the engine number on the timing belt cover is 3743399. This does not match either.

 

The engine number is not on the timing belt cover. It's stamped on the block in an area that's hard to see.

 

Thank you for your reply. Looks like the timing belt cover needs to come off to see the engine number?

 

That photo is looking straight down (note the cam gear with no belt on it at the bottom of the photo)

 

Thanks. I found that place on the engine but cant even get anything in there to clean off corrosion. There is also a manifold cover not shown in the pic. Is there a way to look up engine number by VIN?

 

VIN will tell you the engine family ie the B4204T etc by mapping the 6/7 digits in the VIN. The VIN will also tell you the chassis serial number which is usually good enough to determine part number breaks. A dealer may be able to research the build information from the VIN if you really need the engine's serial number
