### ⭐⭐⭐⭐⭐ Perfect Replacement.
*by  on Reviewed in the United States 25 October 2025*

Perfect replacement for my 94 Silverado K1500. Looks great in my truck. Old one you couldn’t even see the coolant inside of. Great price, seems durable and well sealed. The perfect size and seems like solid plastic.Definitely recommend to anyone looking to replace theirs.
