FAQs

Are these bolts reusable?

No, cylinder head bolts are typically stretch-to-yield bolts and are designed for single use only. They should be replaced every time the cylinder head is removed.

What does 'OE-quality' mean?

'OE-quality' means the part is manufactured to meet or exceed the standards set by the original equipment manufacturer for fit, form, and function.

How do I know if this part fits my car?

You must verify your vehicle's exact make, model, year, and engine type against the compatibility list provided. It is also recommended to check specific measurements and dimensions mentioned in the product description.

What is the thread size?

The thread size for this specific set is M12x1.75x152.

How many bolts are included in this set?

This set includes 10 bolts.

What tool do I need to tighten these bolts?

The spanner size required is M 12. A torque wrench is essential for correct installation.

Can I use these bolts for any engine repair?

No, these bolts are specifically designed for cylinder head applications on the listed compatible vehicles. They are not suitable for other engine components or repairs.

Troubleshooting

Bolt won't thread properly

Ensure the bolt holes in the engine block are clean and free of debris. Verify you are using the correct bolt for the specific hole if there are any minor variations. Double-check vehicle compatibility.

Difficulty reaching torque specification

Ensure you are using the correct torque wrench and following the manufacturer's specified torque sequence and values precisely. Clean bolt threads if necessary, but do not lubricate unless explicitly stated by the vehicle manufacturer for specific bolts (these are typically not lubricated).

Engine misfire or coolant/oil leak after installation

This may indicate improper torque or seating of the cylinder head. The bolts may have been over- or undertightened, or the torque sequence was not followed correctly. Professional inspection and potential re-torquing or replacement of the bolts may be necessary.

Setup, Compatibility & Care Instructions

Compatibility Verification:

Before purchasing, it is crucial to verify that this specific part number (305.430) is compatible with your vehicle. Check your vehicle's year, make, model, engine type, and variant against the provided compatibility list. Pay close attention to any notes regarding measurements and dimensions, as variations can occur even within the same model. Compare the specifications (Thread Size: M12x1.75x152, Bolt Head Design: Internal Serration, Spanner Size: X - M 12) with your existing bolts or manufacturer's specifications.

Installation:

Installation should only be performed by a qualified mechanic. Follow the manufacturer's torque sequence and specifications precisely. Overtightening or undertightening can lead to serious engine damage. Ensure the cylinder head and engine block surfaces are clean and free of debris before installation.

Care:

These are single-use, stretch-to-yield bolts, meaning they are designed for one installation only. They cannot be reused. Proper storage in their original packaging until installation will prevent damage or contamination. No routine care is required as they are installed internally within the engine.
