Q: How to remove the radiator and coolant expansion tank on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: To remove the radiator, first disconnect the battery cable and drain the cooling system. Remove the radiator support cover, upper radiator hose, coolant air bleed pipe, lower radiator hose, and transmission cooler lines. Then, remove the engine cooling fans and mounting bolts, then lift the radiator. Before installation, replace damaged radiator hoses and hose clamps. To remove the coolant reservoir, remove the air filter housing and detach the coolant hoses from the reservoir. Unscrew the mounting fasteners and remove the reservoir. Before installation, make sure the reservoir is clean and free of debris. Installation is the reverse of the removal. Finally, refill the cooling system and check for leaks.
