Hey folks,

Does anyone know which part number corresponds to the item in the perfect blue ring in the picture?

Any tips on changing it would be appreciated as well. Do I need to drain the coolant, or can I clamp the hose before replacing it?

Put the last 7 digits of your car's VIN number into RealOEM website and hit 'browse parts", then 'Radiator' / 'Cooling System Hoses'.....that should get you a diagram of the hoses w/part numbers.

Thank you for your reply. I've been looking at those drawings all day yesterday and still have a hard time identifying the specific tube. I will give it another go.

maybe tell us what you have for year and engine type/model
