This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits select 2001-2026 Chevrolet Silverado and Express, and GMC Sierra and Savana 2500/3500 models (6.6L).

- Higher activation temperatures: 185°F (85°C) and 191°F (88.3°C)

- Manufacturer Part Number: MMTS-CHV-01DH
