How Do You Tighten Or Replace Coolant Hoses In A Chevy Cobalt?
Check the coolant hoses on a Chevy Cobalt twice a year, once in the spring and again in the fall. Replacing the coolant hoses on the Chevy Cobalt takes about 30 minutes and requires basic tools. Replace hoses every four years or at the first sign of wear. Cool the engine for at least an hour after driving. Lift the car using the jack points directly behind the front wheels and set the car on jack stands. Place a collection can or bucket under the drain plug, located at the back side of the oil pan, and remove enough coolant to keep fluid from escaping when removing the hose. Upper hoses need very little coolant removed while lower hoses require draining the radiator completely. Use pliers to open spring clamps or a nut driver for screw clamps. Slide the clamp down the hose until it clears the nipple and twist or pull until the hose releases. Cut the hose with a knife and peel it away from the connection if doesn’t pull off easily. Dip the hose ends in clean coolant and slip the clamps
