New bolts must be used at all times and especially in new cylinder heads, to ensure a satisfac- tory reparation. • It is also very important to carefully follow the bolts torque sequence. All our bolt sets contain the relevant torque sequence.

The use of regular water and poor coolants lead to aluminium corrosion.

CYLINDER HEADS: MAIN CAUSES OF HEAD FAILURE1. Aluminium Corrosion/Cavitation 2. Overheating

3. Injection Failure 4. Overtorque (on caps or injectors)

5. Installation Failure 6. Correct use of Bolts.

Same head, customer used a quality coolant. No corrosion occurred.

Damage caused by cooling system malfunctions.

The proper torque given by the OE manufacturer must always be respected. If not, cracks and fractures will occur affecting the relevant caps or injector housings.

Faults in the injectors flow ( i n c o r r e c t a d j u s t m e n t , dirty hoses, etc.) can cause fuel leaks in the Pre-C o m b u s t i o n chamber.

The cyclic blast of these fuel deposits can burn and erode the alumi-nium of the cylinder head main face.

The correct timing belt positioning and distribution adjustment must be strictly adhered to when repai-ring an engine.

• Old stretch bolts can prevent the achievement of the proper torque and sealing between the cylinder head and block. New bolts must be used at all times and especially in new cylinder heads, to ensure a satisfac-tory reparation.• It is also very important to carefully follow the bolts torque sequence. All our bolt sets contain the relevant torque sequence.
