However, UTV antifreeze may sometimes start blowing everywhere, causing concerns for vehicle owners. Antifreeze blowing everywhere in your UTV can be a frustrating and potentially dangerous problem.
To fix antifreeze blowing everywhere in your UTV, you can inspect and replace the damaged components, such as the radiator cap, water pump, hoses, and thermostat.
Additionally, flushing the cooling system and checking for leaks can help prevent the issue from recurring.
When this happens, fixing the issue before it causes more significant damage to your UTV’s cooling system is essential. This article will discuss why UTV antifreeze blows everywhere and how to fix it.
Reasons Why UTV Antifreeze Blows Everywhere:
1. Failed Radiator Cap:
The radiator cap is in charge of preserving the cooling system’s pressure. If the cap fails, it can cause the antifreeze to boil, leading to excessive pressure buildup.
This buildup can cause the antifreeze to blow out from the radiator cap, resulting in a mess.
2. Clogged Radiator:
The radiator’s primary function is to remove the heat generated by the engine. Over time, the radiator can become clogged with debris, dirt, and rust.
When the radiator is clogged, it restricts the flow of antifreeze, causing it to build up pressure and blow out of the radiator.
3. Water Pump Failure:
The water pump is responsible for circulating the antifreeze throughout the engine. If the water pump fails, the antifreeze won’t circulate, causing it to build up pressure in the cooling system.
This pressure buildup can cause the antifreeze to blow out of the radiator or overflow tank.
4. Overfilled Cooling System:
Overfilling the cooling system can also cause antifreeze to blow out. When the cooling system is overfilled, there is not enough room for the antifreeze to expand when it heats up.
This expansion can cause the antifreeze to blow out of the radiator cap or overflow tank.
One of the most common reasons why UTV antifreeze blows everywhere is overheating. When the engine temperature exceeds the normal operating range, overheating occurs.
The cooling system in the UTV is designed to regulate the engine temperature, but when it fails, the engine can overheat, causing the antifreeze to boil and blow out of the overflow tank.
6. Low coolant level:
Another reason why UTV antifreeze blows everywhere is due to low coolant levels. The cooling system in the UTV requires a specific amount of coolant to function correctly.
When the coolant level is low, the cooling system cannot regulate the engine temperature, and the engine can overheat, causing the antifreeze to blow out of the overflow tank.
7. Blocked radiator or hoses:
A blocked radiator or hose can cause antifreeze to blow everywhere in a UTV. The radiator and hoses are responsible for circulating coolant through the engine to regulate its temperature.
Coolant won’t circulate correctly when they become clogged or blocked, causing the engine to overheat and antifreeze to blow out of the overflow tank.
8. Cracked or damaged hoses:
The hoses in the UTV cooling system are designed to withstand high temperatures and pressures.
However, they can crack or become damaged over time, causing coolant leaks and antifreeze to blow everywhere. Damaged hoses must be replaced immediately to prevent further coolant loss and overheating.
9. Improper antifreeze mixture:
The antifreeze mixture in the UTV cooling system must be of the correct ratio to function correctly.
If the mixture is too concentrated or too diluted, it can cause overheating and antifreeze blowing everywhere. It is essential to check the antifreeze mixture regularly and adjust it as necessary.
10. Old or worn-out thermostat:
The thermostat regulates the engine temperature by controlling the coolant flow through the engine.
It can malfunction when it becomes old or worn out, causing the engine to overheat and antifreeze to blow out of the overflow tank. The thermostat must be replaced immediately to prevent further damage to the engine.
11. Corroded cooling system components:
Corrosion can occur in the UTV cooling system, causing damage to components such as the radiator, hoses, and water pump.
Corrosion can also cause the antifreeze to break down, reducing its effectiveness in regulating the engine temperature.
Regular maintenance and flushing of the cooling system can prevent corrosion and prolong the life of the components. It is also essential to use the correct type of antifreeze to prevent corrosion and ensure the longevity of the cooling system.
