ACDelco 185° & 180° Thermostat Kit (Front & Rear) For GM Pickup With Duramax Diesel (Pair)

Keep your Duramax diesel running at the perfect temperature with this genuine ACDelco thermostat kit.

You're getting two thermostats: one is a 185-degree unit for the front, and the other is a 180-degree unit for the rear, exactly as required for many GM pickups with the Duramax engine.

This is a critical maintenance item to ensure your engine warms up correctly and stays cool under load.

These are quality ACDelco parts, replacing OEM numbers like 97241129 and 97241130.

The kit comes with a 1-year warranty.
