Description

Function of the Cylinder Head

The cylinder head is a core engine component that houses the valves, injectors, and combustion chambers. It seals the top of each cylinder and contains precision-machined passages for intake air, exhaust gases, oil, and coolant. Delphi-specification heads are engineered to work with the Delphi fuel injection system fitted to GW4D20 engines. Cylinder head failure causes compression loss, coolant contamination, overheating, and poor engine performance.

Why order it from Partszar

A worn engine part rarely fails on its own; it loads the parts around it until they fail too. Replacing it when the first symptoms show is what keeps a small repair from becoming a big one, and the engine runs smooth and quiet again once it is done.

• Fitment checked before it is listed. Every part is cross-referenced against the official parts catalogue and OEM part number so it fits first time. If your vehicle is listed above, this is the one you need. Not sure? Send us your VIN using the contact form below and we confirm the exact part for free, no obligation.
• Dispatched fast, tracked to your door. In-stock parts leave within 1 to 2 business days and reach you anywhere in South Africa in 2 to 5 business days with tracking. Back-order parts are sourced directly from our supplier, typically 3 to 4 weeks, and we keep you updated by email.
• Honest about what you get. This is an aftermarket part, built to the original specification without the OEM logo on the casing, which is what keeps the price down.
