  • Anti-seize compound (optional)

Step-by-Step Guide

Step 1: Locate the Spark Plug

The spark plug on the 2003 Polaris Trail Blazer 250 is located on the top of the engine. Remove any covers or components that may obstruct access to the spark plug.

Step 2: Remove the Spark Plug Cap

Carefully pull the spark plug cap off the spark plug. Be sure to pull on the cap itself and not the wire to avoid damage.

Step 3: Remove the Old Spark Plug

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

Step 4: Prepare the New Spark Plug

Check the gap on the new spark plug using a gap tool. The correct gap for the 2003 Polaris Trail Blazer 250 is 0.028 inches. Adjust the gap if necessary. Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the engine.

Step 5: Install the New Spark Plug

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 wrench to tighten it securely. Do not over-tighten, as this can damage the threads.

Step 6: Reattach the Spark Plug Cap

Push the spark plug cap back onto the new spark plug until it clicks into place. Ensure it is securely attached to prevent misfires.
