To remove the cooling system expansion tank, start by draining the engine coolant. Then, remove the fasteners and detach the hoses connected to the expansion tank. Clean the reservoir with soapy water and a brush to remove any deposits and inspect it for cracks. If any cracks are found, replace the reservoir. For installation, simply reverse the removal steps and refill the cooling system. For the removal of the Charge Air Cooler (CAC) reservoir in LS9 engines, begin by loosening the left front wheel lug nuts and raising the vehicle securely on jackstands. Remove the wheel and the passenger's side inner fender splash shield. Drain the cooling system and locate the quick-connect fittings for the charge air cooler reservoir hoses. Use a screwdriver or pick to pull on the open ends of the retaining rings and rotate them around the quick-connector until they can be removed. Separate the hoses from the fittings. Remove the reservoir fasteners and be prepared for coolant spillage. Clean the reservoir with soapy water and a brush, inspecting it for cracks and replacing it if necessary. To install, reverse the removal steps, refill the cooling system, and bleed the charge air cooler.
