Product Overview: This cylinder head assembly is manufactured for Volkswagen CDBA CDCA CKTB CKTC CKUB CKUC CNFA CNFB CNEA CSHA engines and supplied ready for installation as a direct replacement unit. The assembly arrives complete with valves fitted and machined combustion chambers, making it a practical solution for a warped, cracked or valve-damaged original cylinder head.
Key Features: The casting is CNC-machined to original equipment tolerances to deliver correct deck flatness, valve seat concentricity and accurate port geometry. Guides and seats are fitted and honed so sealing is even and compression is balanced across all cylinders, giving a stable idle.
Vehicle Compatibility: This part is listed for Volkswagen, covering model families such as Volkswagen Golf Passat Jetta Tiguan. Always check the engine code and the reference number on the original part against the listing to ensure the correct variant is supplied. Early and late builds of the same engine can use different revisions, so identification from the original component is essential.
Specifications: Key specifications: engine code CDBA CDCA CKTB CKTC CKUB CKUC CNFA CNFB CNEA CSHA; displacement 2.0 L; cylinder configuration Inline-4; material High-Strength Aluminum Alloy; size STD; condition New; warranty 12 Months. Measured characteristics include valve train DOHC 16V with Hydraulic Lifters. Purpose is replacement and repair of the original component in standard form.
OEM / Reference Numbers: OEM and cross-reference numbers covered by this listing are 03L103265EX, 03L103351G, 03L103351Q, 03L103065A, 03L103265HX, 03L103351N, 03L103265E, 03L103351C and 03L103351P. Compare these references with the identification marks on the original component to confirm compatibility.
Applications: Typical applications include head gasket failure repairs, valve damage repairs, engine rebuilds and fleet maintenance on vehicles with cracked or distorted cylinder heads. It also suits preventative maintenance programmes where a failed unit is replaced before secondary damage occurs.
Benefits / Replacement Information: Installing a new head assembly restores lost compression, corrects coolant loss and combustion leakage caused by cracking or distortion, and returns the engine to reliable service. The pre-assembled, pre-machined format avoids the labour and uncertainty of welding, skimming and re-seating an original head. It is a cost-effective alternative to a dealer-supplied assembly while maintaining original equipment dimensions and clearances.
Installation or Fitment Notes: Check the reference number and engine code first, then inspect the block deck for flatness and distortion. Use new head bolts where they are torque-to-yield, a correct replacement gasket, and clean, dry head bolt holes before assembly. Cleanliness during assembly is critical; keep machined surfaces free of swarf, grit and moisture at all times.
