Are you noticing higher temperatures in your truck lately? Has your truck accumulated high mileage? Consider replacing your thermostats with DMAX High Flow Thermostats - they are a direct fit for GM originals. Designed to open at the same temperature as stock, these thermostats open faster and allow for increased coolant flow. This helps lower the temperature of the coolant more quickly when it gets hot, maintains a steady temperature, and reduces strain on the water pump impeller. We highly recommend these thermostats, especially when upgrading your water pump and other components in your cooling system.

Includes:

• 1x Thermostat that opens at 185º
• 1x Thermostat that opens at 180º
  

Notes: 

• Sold as a set
• The oil filler tube and upper coolant pipe seals are not included. They are highly recommended to be replaced during a thermostat replacement to prevent leaks.
