What size are the bolts on a 2017 Chevy Cruze?
The wheel fasteners (lug nuts) on a 2017 Chevy Cruze are M14 x 1.5 with a 60-degree conical (acorn) seat, typically requiring a 19 mm wrench; the installation torque is about 135 N·m (100 ft-lbs). This sizing covers the standard factory wheels, but always verify against your specific wheel package or owner’s manual if you have aftermarket rims.
Understanding bolt sizes for the Cruze involves primarily the wheel hardware, but there are many bolts throughout the vehicle with varying sizes depending on location and trim. The following sections outline the most common and relevant sizes you’re likely to encounter, along with practical guidance for safe maintenance.
Wheel lug nuts: size and specifications
These specifications apply to the standard wheel lug hardware on most 2017 Cruze models equipped with factory wheels. If you’re replacing wheels or using aftermarket hardware, confirm compatibility with the wheel manufacturer and GM guidelines.
- Thread size: M14 x 1.5
- Seat type: 60-degree conical (acorn) seat
- Hex size (across flats): 19 mm
- Quantity per wheel: 5 lug nuts
- Torque (installation): approximately 135 N·m (100 ft-lbs); re-torque after wheel changes and periodically after road use
When changing wheels, use a torque wrench and follow a star/diagonal pattern to ensure even seating. If you switch to aftermarket wheels, verify the seat type and thread size with the wheel supplier and consult the owner’s manual for the correct torque specification.
Other bolts you may encounter on a 2017 Cruze
Beyond the wheel lug nuts, the Cruze contains a wide range of bolts with different sizes across components such as the engine, suspension, body panels, and brake system. There isn’t a single universal size for all bolts on the car; exact dimensions vary by component and trim. Rely on the official service manual or OEM specifications for precise measurements when servicing or replacing these fasteners.
- Engine and transmission bolts: sizes and thread pitches vary by part and mounting location; refer to the service manual for exact values and torque specs.
- Body and suspension bolts: a mix of metric sizes (commonly in the range from small M6/M8 up to larger M12–M14 equivalents, depending on part) with location-specific torque requirements.
- Brake system fasteners: caliper mounting bolts and rotor-related fasteners have dedicated sizes and torques listed in GM braking specifications or the service manual.
Practical takeaway: if you’re replacing fasteners beyond the wheel lugs, obtain the exact size and torque from GM documentation or a trusted repair guide for your exact trim and production date. When in doubt, consult a qualified technician.
How to verify the right bolts for your Cruze
To ensure you’re using the correct hardware for your vehicle, follow these steps:
- Check the owner’s manual and the tire/wheel information label on the door jamb or fuel filler door for lug nut size and torque.
- Consult the GM service manual or an authorized dealer for precise specifications for engine, suspension, and body bolts.
- When replacing non-wheel bolts, match the bolt size, pitch, and grade (strength) to the original part and torque accordingly.
If you’re implementing modifications or using aftermarket components, confirm compatibility and torque values with the supplier and GM guidelines to avoid improper clamping or misfit issues.
Summary
For a 2017 Chevy Cruze, the standard wheel fasteners are M14 x 1.5 lug nuts with a 60-degree conical seat, using a 19 mm wrench and a torque of about 135 N·m (100 ft-lbs). Other bolts across the vehicle vary widely by component, so always refer to the owner’s manual or service manual for exact sizes and torque requirements. Ensuring correct hardware and proper torquing is essential for safe wheel installation and overall vehicle maintenance.
