HSP Factory Replacement Coolant Tank (2011-2014 Chevrolet / GMC)

527-1-HSP is best known as the HSP Factory Replacement Coolant Tank for the 2011-2014 LML equipped Chevrolet and GMC trucks. The HSP Factory Replacement Coolant Tank is something that everyone can benefit from no matter if you are stock or not.

Why would you need the HSP Factory Replacement Coolant Tank for the 2011-2014 LML Trucks?

The factory coolant tanks in the LML Duramax are a failure point that will happen to everyone. We commonly see these tanks fail due to their design and the construction being of plastic. We also see almost every time the tanks quickly yellow and look awful under the hood of these trucks. With so many people trying to make their engine bays look better and better the factory coolant tank is something that in its stock form can not be fixed.

What does the HSP Factory Replacement Coolant Tank do differently?

To start we want you to know that the HSP Factory Replacement Coolant Tank is a drop-in style tank. You do not need anything else to install this and you do not need to change anything from the factory set up to take advantage of this tank. With that being said we did make some changes from the factory tank, we started with CNC bent, CNC cut, and hand-welded aluminum. We did this for two reasons, no more worries about plastic becoming brittle and cracking and we also were able to remove that yellow look that the plastic gets because we can now powder coat the tanks to match your engine bay. The HSP Factory Replacement Coolant Tank also comes with a factory low coolant sensor and all the proper fittings/provisions to clean up the engine bay and install. The HSP Factory Replacement Coolant Tank is made to look good and stand up to not Only the test of time but also all the wear and tear that your truck sees.
