When it comes to utility terrain vehicles, the Kawasaki Teryx is one of the most popular choices, and understandably so. With its rugged good looks and amazing off-road capabilities, you can enjoy the freedom of driving just about anywhere on any terrain. Although the Teryx is one of the best UTVs on the market, you may find the engine making strange noises, leaving you wondering what the problem could be.
When a Kawasaki Teryx engine is making noises, it could be due to overheating, spark plugs deteriorating, or a loud and open engine. Some fixes include replacing your fan sensor, replacing your spark plugs, placing foam under the seats, and covering the engine bay.
In this article, I will discuss the possible reasons why your Kawasaki Teryx may be making engine noises. I will also explain how to fix these issues so that you can spend less time worrying and more time exploring the great outdoors. Let’s get started!
1. The Engine Is Overheating
Overheating is possibly the most common reason for engine noises in a Kawasaki Teryx.
If you have been out on the tracks or exploring the great unknown for an extended period of time and you hear a ticking noise, you should stop immediately. This means that your UTV is in the process of overheating.
Overheating is usually due to a faulty fan sensor wire which leads to the fan being unable to cool down the engine. This is a dangerous situation for your Teryx and can lead to a lot of damage, so it needs to be addressed immediately.
How To Fix
When it comes to overheating, it is best to avoid it all together. You can prevent your Kawasaki Teryx from overheating by doing regular maintenance and not driving it for hours at a time without taking a break. When climbing up and going down steep hills, the motor has to work harder and can overheat faster.
When taking brakes, you can check the following items to help prevent overheating:
- Radiator water levels
- Temperature switch
- Fan plugs
- Fuses
- Fan relay
If, however, your engine still overheats, here are some easy fixes:
- Replace your fan sensor wire. Your fan sensor wire may be faulty, leading to your fan not switching on and the engine overheating.
- Replace the fan breaker. Sometimes, the original breaker gives issues, so replace it with an in-line fuse.
- Invest in a new fan. If your fan doesn’t come on at all, you will have to purchase a new one.
- Clean the radiator. Air in the radiator can cause issues, so burp it to remove any air bubbles and give it a thorough clean.
- Replace the engine. If your engine has overheated and you keep on driving, it can cease. If so, you might have to replace it or have it overhauled.
