Fastener Strength Identification
Most commonly used metric fastener strength property classes are 4T, 6.8, 7T, 8.8 and radial line with the class identification embossed on the head of each bolt. Some metric nuts will be marked with punch, 6 or 8 mark strength identification on the nut face. Figure shows the different strength markings.
When replacing metric fasteners, be careful to use bolts and nuts of the same strength or greater than the original fasteners (the same number marking or higher). It is likewise important to select replacement fasteners of the correct diameter and thread pitch. Correct replacement bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks correspond to bolt strength (increasing numbers represent increasing strength).

Vehicle Identification Number
The number is punched on the front dash panel in engine room (1) and it is also attached on the left side of instrument panel (2) or left side of cowl top panel (3) depending on the vehicle specification.
Scheme 50
Engine Identification Number
The number is punched on cylinder block.
Scheme 51
Transaxle Identification Number
The CVT identification number is located on transaxle case.
