Step-by-Step Guide

Step 1: Locate the Spark Plug

The spark plug on the 2002 Polaris Scrambler 90 is located on the engine's top side. Ensure the ATV is turned off and cooled down before starting the process.

Using the spark plug socket and ratchet wrench, turn the spark plug counterclockwise to remove it. Inspect the old plug for any signs of wear or damage, which can indicate engine issues.

Step 4: Check the Gap on the New Spark Plug

Apply a small amount of anti-seize compound to the threads of the new spark plug if desired. Carefully thread the new spark plug into the engine by hand to avoid cross-threading. Once hand-tight, use the spark plug socket and ratchet to tighten it securely, but do not over-tighten.
