The real deal - certified original
This is an exact factory replacement and is identical and fits exactly. It even comes with a factory manufacturer's holographic certification seal to ensure you confidence that this isn't a cheap knockoff.

Saved me a bunch of money!
Perfect fit. Fixed common issue that causes low coolant warning from faulty coolant sensor molded in tank. The dealer wanted $460 to complete the repair. I was able to complete it in my garage with minimal tools after watch a few videos online.

Happy So Far
I bought this to replace the OEM coolant tank on my 2018 Silverado Duramax. I was experiencing the common problem where the sensor indicated the coolant was low. I had my mechanic install this one and have had no issues so far. It has been in my truck for six months.
