I have a leaking pipe in the cooling system of my Mk Golf. It leaks about a litre in 5 miles. I'm not sure if it's worth trying Radweld with this rate of flow or if I should just try to find a replacement pipe.
The leaking pipe is the one which is oily at the right hand side of the shot, and wet in the centre. The leak is beneath the plastic clip.
Would you try Radweld with this amount of coolant loss? If not, what is this particular stretch of pipe called if I need to replace it? And why is there what appears to be a screw going through it? Is this standard for the clip?
