2. Lack of OEM fit: Although the Pai water pump is designed to fit the International DT466 engine, it may not have an exact OEM fit, leading to potential vibrations or other issues.
3. Shorter lifespan: While the Pai water pump may be more affordable, some users have reported that it has a shorter lifespan compared to the OEM pump.
In conclusion, the Pai 481802 water pump offers cost savings and high-quality materials, but it may come with the potential for leaks, a lack of an exact OEM fit, and a shorter lifespan compared to the original equipment manufacturer part.
