How to Replace a Lower Radiator Hose
Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
Open the hood and locate the vehicle's radiator.
Place a drain pan under the radiator. Remove the lower radiator hose clamps. Remove the lower radiator hose from the radiator to drain the cooling system.
Remove the lower radiator hose from the engine. Install hose clamps on new lower radiator hose. Install new lower radiator hose.
Place the clamps over the hose ends. Tighten the hose clamps.
Refill radiator with a 50/50 mix of antifreeze and distilled water. Fill overflow reservoir with same mixture.
Leave the radiator cap off and start engine. While the engine idles, the coolant will burp (air bubbles) and the level should drop. Refill the radiator to the top.
Install radiator cap.
Pressure test the cooling system once the hoses and coolant are replaced. Check for any other leaks.
Road test the vehicle, keeping an eye on the engine temperature gauge. If the vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after the vehicle has fully cooled down.
