What Causes a Radiator to Clog?

Radiators can become clogged due to various reasons, including:

• Rust and Corrosion: Over time, metal parts can rust, leading to debris accumulation.
• Sediment Build-Up: Minerals in the coolant can form deposits inside the radiator.
• Contaminated Coolant: Using the wrong type or old coolant can introduce contaminants.

How to Clean a Clogged Radiator

Cleaning a clogged radiator involves several steps. Below is a step-by-step guide to help you through the process:

Step 1: Gather Necessary Tools and Materials
