Where does the upper radiator hose go?
The upper radiator hose is where the hot coolant enters the radiator from the engine. It cycles through the radiator, cooling as it goes. When it reaches the bottom, it moves out of the radiator through the lower hose and back into the engine to start the cycle once more.
Can I take off the upper radiator hose?
Use a flat head screwdriver to remove the hose clamps on both ends of the hose. You may have to use a utility knife to remove the hose completely. If so, remember to cut carefully so you don’t damage the radiator.
Are there 2 radiator hoses?
There are two types of radiator hoses, upper and lower. These parts aren’t interchangeable and come in different length and shapes. Connected to the bottom of the radiator and the pump of the engine. While both hoses transport coolant and made from synthetic rubber they have different roles within the cooling system.
How and where does coolant hose failure most often occur?
Electrochemical degradation (ECD) is the number one cause of failure on the rubber portion of coolant hoses. If the ends feel softer and mushier or if you feel gaps or channels inside the hose, the hose is most likely under attack by ECD.
How long does it take to replace upper radiator hose?
