Cylinder Head Assembly 15S4G Used for MG ROEWE MG5 Auto Parts 119kW 215Nm 1.5L: Application Fit and Specification Checks

Why Engine-Code Matching Matters for the MG ROEWE MG5

The MG ROEWE MG5 uses the 15S4G gasoline engine — a 1.5-litre unit rated at 119 kW and 215 Nm. Cylinder heads are precision-machined to the exact bore pattern, port geometry, and fastener layout of a specific engine family. Fitting a head designed for a different code — even one with an identical displacement — risks coolant leaks, valve timing errors, and fastener misalignment. Confirming the engine code is therefore the first and most critical step in the sourcing process.

Hebei Oujia Import And Export Trade Co., Ltd. catalogues this part as the Cylinder head assembly 15S4G used for MG ROEWE MG5 Auto Parts 119kW 215Nm 1.5L, making the engine code, car model, and power figures all visible at the product level so buyers can cross-reference against their vehicle documentation before enquiring.

Selection Criteria

1. Engine Code and Vehicle Model Verification

Before any other check, confirm that the engine code stamped on the donor or recipient vehicle matches 15S4G and that the vehicle is an MG or ROEWE MG5. These two identifiers together define the correct head geometry, combustion chamber shape, and valve-train interface. Do not rely on displacement alone; other SAIC-group engines may share the 1.5 L capacity but differ in architecture.

What to check:

• Engine code label or casting mark on the block
• Vehicle model and variant documentation (VIN decode, workshop manual)
• Rated output: 119 kW / 215 Nm (confirms the specific calibration-level variant)

2. Output Rating Confirmation (119 kW / 215 Nm)

The 15S4G engine appears in different output states across the SAIC range. The 119 kW / 215 Nm specification identifies the precise variant. Port dimensions, combustion chamber volume, and valve sizing are calibrated to this output level. Ordering against the correct output rating prevents fitment issues that would otherwise only appear on reassembly or first start.

3. Material and Construction Specification

The assembly is constructed from cast iron, the industry-standard material for cylinder heads in this class. Cast iron provides the thermal mass and machinability needed for reliable long-term sealing at the head-gasket interface. Buyers should confirm the material specification is met by the supplied assembly, particularly when sourcing aftermarket parts where aluminium or mixed-material alternatives may be offered by other suppliers.

4. Parts Inspection Criteria

Hebei Oujia Import And Export Trade Co., Ltd. applies a structured inspection framework to each assembly before shipment. The inspection covers four areas:

Buyers sourcing in volume should ask their supplier to detail which of these checks are performed and at which stage of production, as the scope and documentation of inspection directly affects downstream warranty claims.

5. Packing and Logistics Compatibility

The assembly is available in neutral or customised packing, with a minimum order quantity of 1 set — suitable for both trial orders and bulk procurement. Shipment is available by sea or air from multiple Chinese ports (Xingang, Qingdao, Shanghai, Shenzhen, Guangzhou), which gives distributors flexibility on lead-time versus freight-cost trade-offs. Buyers operating in markets with strict import labelling requirements should specify customised packing at order stage.

6. Warranty Terms

The assembly carries a 12-month quality warranty. Procurement teams integrating this part into an aftermarket distribution channel should confirm whether the warranty period aligns with their own customer-facing warranty obligations and document the warranty coverage scope before listing the part.

When This Assembly Does Not Apply

This assembly is specified for the MG ROEWE MG5 with the 15S4G engine. It is not applicable to:

• Other SAIC, MG, or ROEWE models using different engine codes
• 1.5 L engines in other vehicle brands (such as the Daewoo/Chevrolet L2B or similar)
• Higher- or lower-output variants of 1.5 L SAIC engines where port or chamber dimensions differ

If you are sourcing for a different platform, Hebei Oujia Import And Export Trade Co., Ltd. also catalogues cylinder head assemblies for other engine families — including the MAXUS V80 (SC25R136Q5 2.5L), Chevrolet/Daewoo L2B 1.5L, Hyundai G4LC 1.4L, Mazda R2 2.2L, and Chevrolet/Opel F16D4 — each specified to its own engine code and vehicle model.

Summary: Key Checks Before Ordering

1. Confirm engine code 15S4G on the vehicle or engine documentation.
2. Verify the vehicle is an MG or ROEWE MG5 — not another model sharing the same platform.
3. Cross-check the output rating (119 kW / 215 Nm) against the specific variant in the fleet or repair order.
4. Review the material specification (cast iron) against your application and climate requirements.
5. Understand the inspection scope — ask for documentation covering dimensions, appearance, function, and material checks.
6. Align packing and logistics requirements (neutral vs customised, sea vs air, port selection) at the enquiry stage.
7. Review the 12-month warranty terms relative to your own distribution or repair obligations.
