3.0 Duramax Coolant Valve: GM Just Dropped New Special Coverage (N252508341) LM2

Описание: GM just dropped Special Coverage N252508341 for the LM2 3.0 Duramax diesel, and it directly impacts trucks with the coolant control valve issue. In this video, I explain what the new policy covers, which Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade models are included, and what you need to know if your check engine light comes on with a coolant valve code.

If you own a 2020–2023 3.0 Duramax, this update could save you money on repairs under GM’s extended coverage. We’ll walk through how the coolant control valve works, why it fails, and what GM’s new warranty support means for real truck owners.

For more details, check out the full article on DuramaxNews.com linked below. I’ll also share related videos and the exact parts, filters, and tools I personally recommend as a GM tech and 3.0 Duramax owner.

👉 Whether you’re maintaining, troubleshooting, or upgrading your truck, this channel is here to help you extend the life of your Duramax.
