After I put it to the test, I must say that this Hoses & Pulleys product is amazing. The HVAC heater assembly worked flawlessly and provided warm air in my car during the cold winter months. The installation process was simple and the overall construction of the product was very durable .The only downside would be that it is a bit pricey compared to other car belts in the market. Nonetheless, its quality and durability make it worth the investment..
