Elring Head Bolt Set Ford Focus C-Max 1.8Tdci 96> | 027.850 | Euro Car Parts

This is a head bolt set manufactured by Elring, specifically designed for the Ford Focus and C-Max models equipped with the 1.8 TDCi diesel engine – applicable to vehicles produced from 1996 onwards (and later iterations of this engine family). This kit provides all the necessary bolts for reassembling the cylinder head following maintenance or repair work.

Head bolts are critical components within an internal combustion engine, responsible for securely clamping the cylinder head to the engine block. Maintaining correct cylinder head gasket compression is paramount for efficient combustion, preventing coolant leaks, and avoiding oil contamination. Over time, these bolts can stretch or fatigue due to thermal cycling and the immense pressures exerted during engine operation. Replacing head bolts is generally considered best practice whenever the cylinder head is removed, ensuring a reliable and lasting seal.

Elring is a well-respected manufacturer of engine sealing components and gaskets, known for its adherence to Original Equipment (OE) standards and quality control processes. This head bolt set reflects that commitment, utilising materials selected for their strength, durability, and resistance to corrosion within the harsh engine environment.

Key Features & Considerations:

• Vehicle Compatibility: Specifically engineered for Ford Focus and C-Max models powered by the 1.8 TDCi diesel engine (from 1996 onwards). Please verify your vehicle’s specific engine code to ensure compatibility – consult your vehicle documentation or a trusted mechanic if unsure.
• Complete Set: This kit contains all the head bolts required for a complete cylinder head reassembly. The exact number of bolts included will correspond to the engine's design; typically, this is around 10-20 bolts depending on the specific engine variant.
• Material Composition: These bolts are constructed from high tensile steel alloys, chosen for their ability to withstand significant clamping forces and repeated stress cycles. The material specification ensures resilience against deformation under load.
• Surface Treatment: A protective coating is applied to each bolt to prevent corrosion and facilitate installation/removal. This coating also helps to ensure consistent torque readings during tightening procedures.
• Torque Specifications: Correct torque application is absolutely critical when installing head bolts. Refer to the vehicle’s workshop manual for precise torque settings and tightening sequences. Incorrectly torqued bolts can lead to gasket failure, engine damage, or even catastrophic mechanical issues.
• Stretch-to-Yield Design (Potential): Some 1.8 TDCi engines utilise stretch-to-yield head bolts. These bolts are designed to permanently deform slightly when tightened to the specified torque, providing a more accurate and reliable clamping force. If your engine uses these, it is *essential* not to reuse old stretch-to-yield bolts; replacement with this kit is mandatory.

Importance of Regular Maintenance:

While head bolt failure isn't necessarily a frequent occurrence, it’s often linked to overheating events or previous cylinder head gasket failures. Proactive maintenance and addressing any cooling system issues promptly can help prevent premature wear on these critical components.

Installation Notes:

• Always use a calibrated torque wrench when tightening head bolts.
• Follow the manufacturer’s recommended tightening sequence precisely. This ensures even pressure distribution across the cylinder head gasket. Typically, this involves multiple passes with increasing torque values.
• Clean all mating surfaces thoroughly before installing the new head bolts and gasket.
• Consider using a thread lubricant specifically designed for head bolts to ensure accurate torque readings and prevent galling.
• If you are not confident in your mechanical abilities, it is strongly recommended that this work be carried out by a qualified mechanic.

This Elring head bolt set provides a reliable and cost-effective solution for restoring cylinder head clamping force on Ford Focus and C-Max 1.8 TDCi models. By utilising high-quality materials and adhering to stringent manufacturing standards, Elring ensures these bolts meet the demands of modern diesel engines.
