How do you remove and install a Coolant Reservoir on Cadillac CTS?

To remove the cooling system, start by draining it. On 2007 and earlier models, remove the left side cowl panel and disconnect the hoses. If the model has a manual transmission, unbolt the clutch master cylinder reservoir and set it aside. Slide the master cylinder forward without disconnecting the brake lines and position it out of the way. Remove the surge tank mounting fasteners and take out the tank. On 2008 and later models, remove the fasteners securing the coolant reservoir to the fender, lift it up to disconnect the hoses, and disconnect the fluid level sensor if present. Clean the tank with soapy water and a brush to remove any deposits and inspect it for cracks. If a crack is found, replace the reservoir. To install, simply reverse the removal steps.

Cadillac CTS Coolant Reservoir

Coolant Reservoir is commonly featured in Cadillac CTS automobiles; it is designed to prevent coolant spilling along with entering air into the engine cooling system. There are two main types of Coolant Reservoirs used in CTS vehicles: two types of the tank systems; the overflow tank systems and the expansion tank systems. In the overflow system, coolant gets to the recovery tank in cases of pressure build up beyond the cap's limit while in the expansion system, the tank is an integral part of the pressure containing cooling system and serves to accept the coolant fill in during expansion and shrinkage during contraction. Annual examination is advised to look for cracks or pinhole leaks and change of color due to product deteriorization from the years or from dirty coolant. As to The Coolant Reservoir, it regulates the amount of coolant required for proper operation of the Cadillac CTS' engine.

Each OEM Cadillac CTS 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.
