INA ZG0235 Engine Timing Chain Guide - Upper

Overview

INA engine timing chain guide part number ZG0235 is an upper guide for select Mercedes-Benz applications. It is built to meet or exceed OE quality and performance, with plastic material formulated to match OEM PA66 and PA46 grade requirements for material and hardness.

Fits 2011-2018 Mercedes-Benz applications across multiple models, including upper timing chain guide locations. This part cross-references Monroe Shocks & Struts (e.g., 5520235100) for the same application.

Key Features

• Engine timing chain guide for upper chain routing
• OE-quality replacement from INA
• Plastic construction matched to OEM PA66 and PA46 grade targets
• Engineered for material hardness consistency
• Part number ZG0235 for accurate ordering and service matching

Detailed Description

INA ZG0235 is an upper engine timing chain guide used in a wide range of Mercedes-Benz engines, including C-Class, E-Class, CLS, SLK, ML, GLK, GL, G-Class, and AMG applications. The guide supports proper timing chain path control in the valve train, helping maintain chain alignment under engine operating conditions. Fitment includes models such as Mercedes-Benz E350, S63 AMG, and GLE350, with application-specific notes tied to INA Global Number 552 0235 100.

The part number ZG0235 is useful when matching service parts for Mercedes-Benz timing system repairs. INA timing chain guides are specified to align with OE expectations, and the material formulation is selected to mirror OEM plastic grade and hardness characteristics. For technicians servicing Mercedes-Benz E350 or SLK55 AMG timing components, ZG0235 provides a direct reference point for the correct upper guide application.

What It Helps Address

• Timing chain noise caused by worn guide surfaces
• Chain misalignment in the valve train
• Plastic guide wear from extended engine use
• Incorrect timing component replacement during service
• Fitment confusion when sourcing Mercedes-Benz upper guide parts

Installation Notes

Verify engine code, model year, and upper guide application before installation. Confirm the INA Global Number 552 0235 100 against the removed part and service documentation. Timing system service should follow manufacturer procedures for chain alignment and component inspection.

Quality Assurance

INA states that this timing chain guide is made to meet or exceed OE quality and performance standards. The plastic material is matched to OEM PA66 and PA46 grade requirements for material and hardness consistency.
