location of crankshaft sensors in 2004 infinity M45
5 Qts
The factory 2003 Infiniti M45 shocks are monotube. It is evident by the huge piston size. For a premium luxury sports sedan as heavy as the M45, monotube shocks makes sense as they provide stable control on longer drives on different road conditions.
The sensors are wheel position specific. They should reset themselves. If they are not in correct position they will not reset.

The oil capacity for a 2007 Infiniti M 45 is approximately 5 quarts of oil. The oil can be purchased at any auto parts store.
The cam position sensor for a 2003 Infiniti M45 will cost about $30-40 for an aftermarket brand. For an OE (factory) part, your best bet is to call the Infiniti dealer for an exact quote. Theoretically it should be in that same price range, although it's not uncommon for OEM parts to be more expensive than aftermarket brands.
Infiniti recommends using premium grade fuel in the M45 and also in nearly every other car they make.
It is about 227 miles between Dagenham RM8 3BL, UK and Whitefield M45 8DZ, UK.
