How to remove and install Coolant Reservoir?

Drain the cooling system. If the coolant is relatively new and still in good condition, it can be saved and reused. Note: On four-cylinder engine models, there is an additional drain plug on the bottom of the water pump. Be careful to clean up any spilled coolant as stated in the Warning at the beginning. Disconnect the coolant reservoir hoses by sliding the hose clamp away with pliers and then removing the hose from the reservoir fitting. Remove the coolant reservoir mounting fasteners. Clean out the reservoir with soapy water and a brush to remove any deposits inside. Inspect the reservoir carefully for cracks. If you find a crack, replace the reservoir. Installation is the reverse of removal. Refill the cooling system with the proper concentration of antifreeze.

Pontiac G6 Coolant Reservoir

The Coolant Reservoir in Pontiac G6 is yet another component of the engine cooling system; its main function is to avoid coolant spillage on the ground and to ensure no air is trapped in the system. There are two types of Coolant Reservoirs used in G6 vehicles: overflow tank systems and expansion tank systems are the two fundamental categories in this case. In the overflow system, in case of pressure build up beyond the rating of the cap, the coolant moves to the recovery tank while in the expansion system, the tank forms part of the sealed cooling system and provides for the expansion of the liquid or contraction as applicable. It is advised that, at least once in a while, the Coolant Reservoir should be inspected for any signs of cracks or leakages or any sign of rusting.

Each OEM Pontiac G6 Coolant Reservoir we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
