Belt Drive Systems

The 12PK designation refers to the specific size and configuration of the fan belt. The 12 indicates the number of ribbed grooves on the belt, while PK signifies it is part of the Poly-V or serpentine belt system. This design has become the standard for modern vehicles due to its efficiency in powering multiple components such as the alternator, water pump, power steering pump, and air conditioning compressor.

3. डिप्रिसियसन नयाँ भ्यानको मूल्य प्रयोगमा ल्याउँदा झन् छिटो घट्ने गर्दछ। यद्यपि प्रयोग गरिएको भ्यानमा यो समस्या कम हुन्छ। एक पटकमा गाडी किनिसकेपछि, यसले पहिले नै केही मूल्य घटाइसकेको हुन्छ, जुन पुनः बिक्री गर्दा फाइदाजनक हुन्छ।

5. Visible Cracks or Damage Inspecting the timing belt for visible signs of wear, such as cracks, fraying, or missing teeth, is crucial.

Unlike older belt designs prone to drive belt slipping, modern PK belts use advanced synthetic materials like EPDM (ethylene propylene diene monomer) that resist wear and maintain a strong grip on pulleys. This minimizes unnecessary energy losses, allowing the engine to work efficiently. As a result, fuel consumption decreases, leading to lower carbon dioxide (CO₂) emissions.
