Tracker / Trax - Europe 2013-2020 F18D4 F18D4 Bare Cylinder Head Assembly for 1.8 Petrol Chevrolet Cruze Lacetti Optra Tracker / Trax - Europe 2013-2020 – OEM 55571690

Product Overview: Engineered for Chevrolet F18D4 engines, this cylinder head assembly is a complete replacement unit built to original equipment tolerances. It is supplied fully assembled with valves, guides and seats installed, so a cracked, warped or valve-damaged original head can be replaced without additional machining work. The head is intended for 1.8 litre applications and is finished in aluminium alloy.

Key Features: The head is machined on CNC centres for correct deck flatness, precise valve seat angles and matched combustion chamber volumes. Pre-installed, honed valve guides and cut seats produce even sealing and consistent compression on every cylinder. Machined cam carrier surfaces maintain correct bearing clearance and reliable camshaft support for the DOHC valvetrain. The finished component is inspected and packed to protect its machined surfaces during transport and storage.

Vehicle Compatibility: Compatible applications include Chevrolet, with listed fitment across Tracker / Trax - Europe, New EPICA and Tracker / Trax - GMSA. Documented fitment covers model years 2013-2020 and 2007-2015. If a vehicle is not shown in the compatibility list, cross-reference the engine code and original reference number to confirm fitment.

Specifications: Key specifications: engine code F18D4; displacement 1.8 L; cylinder configuration Inline-4; material Aluminum Alloy; size Standard Size; condition New; warranty 12 Months. Additional dimensional and build data includes valve train DOHC 16V. It is supplied in standard size, so no undersize bearings or additional machining are required at assembly.

OEM / Reference Numbers: No alternative reference numbers are published for this listing; identification should be made from the engine code and vehicle application details.

Applications: Typical applications include head gasket failure repairs, valve damage repairs, engine rebuilds and fleet maintenance on vehicles with cracked or distorted cylinder heads. Keeping this assembly on the shelf helps workshops cut vehicle downtime on a common repair.

Benefits / Replacement Information: Fitting this assembly restores compression, eliminates coolant loss through cracked castings and returns consistent combustion. The pre-assembled, pre-machined format avoids the labour and uncertainty of welding, skimming and re-seating an original head. A new casting removes the risk that a repaired original head will crack again after the engine has been rebuilt.

Installation or Fitment Notes: Prior to assembly, verify the part number and engine code, and check the block deck and head bolt threads for condition. Fit a new gasket and, where required, new torque-to-yield bolts, ensuring the bolt holes are clean and free of fluid. A qualified technician should carry out fitment using the manufacturer's documented procedures and torque values.
