Many riders install guards on the radiators that comprise stainless steel, black, and dirt-repellent covers. They repel stones, dirt, and road salt because of their specific mesh and design.
Do Motorcycle Radiator Guards Cause Overheating? Motorcycle radiator guards do not cause overheating because of balanced airflow, do not affect the cooling system, and the fan regulates the increased temperature. Air can easily pass through its mesh and design, and you will notice similar temperature readings.
These guards are shields or protective covers for these radiators. They are not mandatory, but many individuals use them to protect these parts.
Why do motorcycle radiator guards not cause overheating?
Many people install radiator guards because they do not affect the cooling system of motorcycles. They do not cause overheating because of the mentioned reasons.
Balanced airflow
The radiator guards of the motorbike protect against dust, debris, and rocks. However, they have a specific design with different patterns.
The hollow portions have variable patterns according to their layouts. In addition, their standard mesh size is 16×12 inches.
They have flat plastic sheets that comprise these dimensions. However, they can fit all radiators due to this size.
The radiators of various motorbikes increase the contact of hot coolant with the external air. They balance the internal heat of the engine and stabilize its efficiency.
The protective sheets on the front side of the built-in radiator allow a balanced airflow. The external air can enter it and work with the coolant according to the standard efficiency.
In such circumstances, its temperature stabilizes with a balanced flow of the external air inside the system. As a result, they do not cause overheating of the motorcycle and its engine.
Also, the air can pass through the specific mesh size properly. These plastic-based flat sheets do not block the airflow passages because of their built-in gaps and specific designs.
The coolant works at a standard level and prevents overheating according to the fan’s performance. Their specific designs do not block the cool air which flows towards the radiator and reduce the heat level.
Then, the coolant stabilizes the engine and prevents its overheating.
No effect on the cooling system
The radiators reduce the temperature of the engine and stabilize its efficiency. Road pebbles can hit them when they do not comprise the protective covers.
Also, their cracks reduce the coolant stability and cannot maintain the temperature. Many people install protective guards over them to reduce their direct exposure to debris and pebbles.
However, their covers do not affect the cooling mechanism because they have stable air flow and ventilation. The coolant system of the motorcycle works despite these protective covers.
These protective barriers are lightweight, but they have high stability. Furthermore, they can fit the radiator by following its frame and air flow passages.
They do not interfere with the airflow. The cool air flows inside the cooling mechanism, which reduces the overheating.
Furthermore, they cannot cause the overheating of the stock engine because they do not affect the cooling system.
Fan regulates increased temperature
Sometimes, the radiator guards can increase the temperature of the coolant system. Their variable mesh size can block the airflow.
It decreases the overall ventilation, and the airflow reduces by 10%. In such circumstances, its fan activates and regulates the overheating.
Therefore, it rises to a few degrees while you install these protection guards on the radiators. Similarly, the fan activates and reduces the heat.
It can stabilize its efficiency and improve the coolant performance. These fans are heat regulators and prevent the cooling system from overheating.
These covers are compatible with these electrically working fans. However, these fans can reduce overheating, which increases after the installation of these guards.
Then, they do not cause overheating of its stock engine.
Similar temperature readings
They have specific radiator guards with plastic-containing flat sheets. These sheets have particular gaps in the airflow.
These flat sheets are mesh sizes of these protection guards over the coolant system of the motorbike. The operational heat level of motorcycles is about 155°F (68°C).
However, the range varies according to their models and the size of the cooling system. A few have a high operational temperature range of 220°F (104°C).
The manufacturing companies modify these ranges according to the climate conditions of a specific area. Furthermore, they can control and modify these ranges according to the external environment.
These limitations vary because of the high or low climate heat. Their cooling systems regulate it and stabilize overheating according to variable climate conditions.
In addition, you can check the temperature limits of your motorbike before installing the flat sheet protection guards over this part.
Using a specific radiant thermometer is better for checking the limitations. You can use a radiant thermometer to identify the heat level without touching the radiator or cooling system.
Also, it can measure the heat range of the engine from the surface because it has specific sensors. It determines the stable running temperature of your motorbike.
Then, you can install the protective guards on the radiator. Furthermore, after riding for a few miles, it can increase overheating, according to various assumptions.
Then, you can stop and check the temperature of its cooling system, frame, and engine. It is not advisable to check the temperature after cooling the motorbike.
Now, you can compare the readings of internal engine temperature before and after installing the protective plastic guards on the radiator.
These readings are similar in several circumstances, and you cannot identify a difference between the readings.
Moreover, these people ride them for several miles to increase the temperature of the built-in cooling system. Then, they compare the old readings of temperature with the new values.
It is possible to find similar readings because these radiator guards do not excessively overheat the engine.
You can measure multiple readings to ensure temperature differences and radiator stability. However, checking it is better after installing them on the outer side.
When does a motorcycle radiator guard cause overheating?
Sometimes, the radiator guards can cause overheating of the engine. They can change the temperature of the cooling system to a few degrees.
However, they can increase the heat level when their fan malfunctions. This fan can regulate the motorcycle temperature and reduces the heat level.
But, it malfunctions and cannot stabilize the heat flow. The mesh size of these protective guards allows stable and balanced airflow.
In a few conditions, the airflow can reduce to 10% to 20% and affects the performance of the coolant. Also, the reduced airflow can increase the temperature of the coolant system and causes overheating.
In such circumstances, the malfunctioning fan cannot stabilize the airflow. It cannot control the high temperature of the system.
However, this fan malfunctions because of internal electrical failures. Its wires break, and the fuse blows when the electric circuit undergoes power fluctuations.
In such circumstances, its blades do not move, and the fan cannot decrease the temperature, which leads to overheating of the engine.
The malfunctioning fan can increase the temperature. Then, the reduced airflow increases more heat which affects the performance of the cooling system and engine.
Furthermore, 16×12 inches is the standard mesh size of these radiator guards. These are stable options with better fitting properties.
A few people select the wrong mesh sizes, which results in an incorrect installation. Also, they do not fit on the radiator and lose their efficiency in protecting it from road debris and rocks.
The closed gaps of their plastic flat sheets reduce the balanced airflow. As a result, proper ventilation reduces, which increases the temperature of the built-in coolant system.
The internal heat level increases and affects the engine performance. In such circumstances, they can cause excessive heating of the motorcycle engine, frame, and cooling system.
