Review VOLVO MACK TRUCK New Genuine Oem Belt Tensioner

The Volvo Mack 87GB47A Belt Tensioner 25195072 is a crucial component of the Volvo Mack trucks' engine cooling system. This tensioner ensures the proper alignment and tension of the serpentine belt, which drives various accessories such as the alternator, air conditioning compressor, and power steering pump.

The 87GB47A Belt Tensioner is designed with a robust construction, ensuring durability and reliability under heavy-duty operating conditions. It features a precision-machined pulley with a diameter of approximately 3.3 inches (85 mm) and a bore size of about 1.5 inches (38 mm). The pulley is made from cast iron for enhanced strength and longevity.

The tensioner's design includes a spring-loaded tensioning mechanism that automatically adjusts belt tension as the engine warms up or cools down. This feature maintains optimal belt tension, ensuring efficient power transmission and preventing premature wear of the belt and related accessories.

Additionally, the Volvo Mack 87GB47A Belt Tensioner 25195072 comes with a flexible, heat-resistant rubber cover that shields the tensioner from engine heat and other environmental factors. This protective covering also helps to reduce noise generated by the belt and related components, contributing to a quieter operating environment.

The installation of the 87GB47A Belt Tensioner is straightforward and can typically be accomplished with common hand tools. Volvo Mack provides detailed installation instructions to ensure a proper fit and function. Replacing a worn-out or faulty belt tensioner with a new, genuine Volvo Mack part like the 25195072 can help maintain the overall performance and longevity of the engine cooling system in your Mack truck.

Volvo Mack 87-gb47a Belt Tensioner (Part Number 25195072) is an essential component in the Volvo Mack truck's drivetrain system. The belt tensioner ensures that the drive belts are properly tensioned, which is vital for the engine's proper functioning and overall truck performance. Let's discuss some pros and cons of buying this part.

1. Ensures Proper Belt Tension: A faulty or worn-out belt tensioner can lead to drive belt slippage, which can negatively impact the engine's performance.

By replacing the faulty belt tensioner with a new one, you can prevent potential damage to these components, saving you from costly repairs down the line.

3. Improves Truck Longevity: Regular maintenance and replacement of worn-out parts, such as the belt tensioner, can help extend the life of your Volvo Mack truck.

2. Labor Costs: The cost of labor to replace the belt tensioner can also add to the overall repair cost. It is recommended that you have the replacement done by a qualified mechanic to ensure proper installation and avoid any potential issues.

3. Time Consuming: Replacing a belt tensioner can be a time-consuming process, especially if you are doing it yourself. It may require you to remove other components to access the tensioner, which can add to the overall time spent on the repair.

Investing in a new Volvo Mack 87-gb47a Belt Tensioner (Part Number 25195072) is an essential part of regular truck maintenance.
