Problems with Kawasaki Mule Pro FXT:
Kawasaki Mule Pro FXT is a durable workhorse that has gained an excellent reputation for work-related tasks within years. It has some excellent characteristics that add comfort during its usage for riders and has made it a well-rounded and excellent piece in the UTV market.
But as we know, there is no perfection in materialistic pursuits, so it also holds some significant drawbacks that should be kept in mind to avoid mishaps during off-roading. The problems usually arise due to a lack of maintenance and transmission failure.
1. The Problem of Heat in Kawasaki Mule Pro FXT:
One of the common complaints of the Kawasaki Mule Pro FXT is about the heating issue in this vehicle.
The heat generated from the radiator blows into the vehicle's cabin and can affect the cabin area. In addition, this heat can affect the legs and feet of the driver if there is no windshield on the vehicle.
Heat is generated when the radiator of the vehicle vents beside the dashboard and blows some warm air out on the driver’s footwell region. It becomes highly inconvenient to bear during hot days of the year.
How to Fix:
Heating issue is a common problem that is not adequately addressed, but a few strategies can be adopted to prevent this issue:
Installation of a Hood Scoop:
You can install a hood scoop in your Kawasaki Mule Pro FXT that force the air to pass out under the hood and can offset the hot air.
The Hood scoop also helps keep the radiator cool so it can produce less warm air. Various hood scoops are readily available in the market, and in some vehicles, they are already pre-fitted. You can get your hood scoop for your Kawasaki Mule Pro FXT for just $100.
The Hood scoop is fitted with your vehicle using heavy-duty brackets that keep it in its place. Hood scoop is easy to install with brackets and latches and increase the flow of cool air.
Removing the Doors of Vehicle:
If there is a heating issue in the vehicle, you can remove the doors to resolve it.
It is not an ideal fix for this issue, but it can still create a noticeable difference in it and allow some additional air to flow through the vehicle. In addition, it helps dissipate the heat from the cabin area.
Removing the Cover of Hood:
You can remove the hood cover and the hood scoop to dissipate heat from the cabin. But it is not a natural approach to doing so.
2. Problem with Oil Filler Cap in Kawasaki Mule Pro FXT:
In 2020, a recall was issued for FX, FXR, and FXT models built between 2015 and 2020, as well as DX and DXT models built between 2016 and 2020, due to the potential for the oil filler cap to dislodge.
The oil filler cap is located on the valve cover of the engine. It is susceptible to popping off, spilling hot oil all over the vehicle, and creating a fire hazard.
This can happen when the breather tube becomes filled with exhaust gas-induced moisture, which freezes and obstructs the tube, causing a build-up of pressure that leads to the oil fill cap being ejected.
How to Fix:
You can fix this problem by installing an oil catch in the models of this vehicle. It is recommended to install an oil catch even if your model has not shown up this problem yet.
3. Oil Leakage in Kawasaki Mule Pro FXT:
As mentioned above, it is recommended to install oil catch cans that can prevent oil spillage in the vehicle.
Each oil catch can is equipped with a transparent drain plug. If oil and water accumulate in this plug, it could begin to overflow, causing a mess on the floor.
How to Fix:
You can fix this oil leakage issue by seeking help from the owner’s manual. It is recommended to remove the drain plug that is present at the bottom of the catch can.
If this transparent drain plug gets clogged with oil or water accumulates, you can remove the drain plug to make the can empty. Make sure to regularly check the drain plug to avoid oil accumulation and overflow of oil from it.

- Step 2: To bypass this switch, you can press down the brake pedal and try to start the Mule in gear.
- Step 3: Inspect the spark plugs for any foreign substances such as fuel, oil, or coolant, and check the color of the tips to make sure they are not grey or black, which would indicate fouling.
- Step 4: If you heard a whining sound coming from the fuel tank before your FXT stopped working, it’s likely the fuel pump has become faulty and needs to be replaced.
