If your motorcycle is in need of a coolant change, you may be wondering how to go about tackling the job. If so, read on to learn the basics of changing your motorcycle's coolant.

Step 1 - Drain the Coolant

After placing a bucket beneath your motorcycle to catch the discarded coolant, use a wrench to carefully remove the coolant drain bolt. Once all the old coolant has been drained into your bucket, use a washcloth to give your drain bolt a vigorous cleaning, then reattach it. If your drain bolt is exceptionally filthy, however, you may want to take this opportunity to replace it.

Step 2 - Apply New Coolant

Now that your old coolant has been successfully drained, open up the motorcycle's coolant cap and pour in the amount of coolant recommended by your owner's manual. Use a washcloth to vigorously clean the coolant cap. Once the cap has been cleaned, securely reattach it. As was the case with the drain bolt, you may want to consider replacing your motorcycle's coolant cap if it strikes you as particularly dirty.
