2011-2016 Duramax Engine Coolant Thermostat Kit (10513)

Got a truck engine that isn't heating up or overheating? Often, the issue is faulty thermostats. Over time, thermostats can stick open or closed, causing heating or cooling issues. No worries! Just swap them out for new ones with this kit.

The thermostat at the front is situated in the forward location of the thermostat housing and is marked by its symmetrical appearance. It opens at 185°, giving way for coolant to move towards the radiator.

The rear position of the thermostat is found near the firewall. You can spot it by its offset design and it also has built-in bleeder valves. It opens at 180° to let coolant flow to the radiator.
