Mercedes Hood Release Cable - Metzeler 204880085964

Product Information

The hood release cable is a mechanism that allows the driver to open the vehicle's hood from inside the cabin. It consists of a flexible metal cable that runs inside in a protective plastic sheathing much like a bicycle brake cable. It connects the interior lever to the latch on the hood. The operation should be smooth, without any gritty feeling in the lever when unlatching the hood release. All modern vehicles also have a secondary safety latch that must be manually lifted to fully open the hood.

Key components of the hood release system include the release handle or lever (usually plastic), the cable itself with a ferrule, the sheath that protects the cable, and the hood latch. The cable is typically made of steel to handle the tension required to release the latch, while the sheath protects it from wear and external elements like dirt, moisture, and rust. The latch mechanism under the hood is spring-loaded to ensure it locks the hood securely when closed but pops free when unlatched.

Hood release cables may fail or require replacement due to several common issues. Over time, the cable can stretch, making it difficult to pull the release handle far enough to disengage the latch. The cable can also fray, snap, or rust, especially in older vehicles or in regions with harsh climates. Additionally, the sheath can wear out or crack, exposing the cable to corrosion. If the cable becomes misaligned or disconnected, it can prevent the hood from opening.

• Stretched Cable: Corrosion on the latch or the prong that engages the latch will increase strain on the cable. Make sure to grease the latch (or latches) to make sure the operation stays smooth and protects the metal surface from corrosion. Repeatedly pulling the hood release cable can stretch it, eventually to the point where you cannot pull it far enough to disengage the latch.
• Hood only partially releases: Most European cars have two hood release latches, with the cable only engaging the first one. Then another cable connects the two latches. Sometimes if both sides aren’t releasing correctly, you can adjust the location of the latches to get a more positive pull on both latches. If that doesn’t work inspect both cables for stretching or corrosion.
• Broken handle: If you broke the handle on the hood release cable, there are a few things to consider. There is probably corrosion on the latch that leads to a harder pull. The plastic handle is usually the weakest part of the system so it's important to inspect, refurbish, or replace the latch at the same time you replace the cable and handle assembly.
• Broken Cable: Much like the broken handle, if the cable has snapped the latch should be inspected or replaced along with a new cable.
