Radseal

[taichiperson]

Has anyone used this? The car has just come back from the garage with a few minor problems, one of which was the radiator leaking - I've put a couple of litres of water in to top up over a week. They replaced a cap on the drainage hole, but it's still leaking. I've been told to try Radseal as a cheap/ quick alternative. Any advice please, as I'm fed up going back and forth to the garage.

I have never been too chuffed with Radseal. It can clog up other places rather than the one you are hoping to bung up! It never seemed to have any real effect and the only real solution is to bin the radiator and get a new one. Having said that...are you sure its the rad thats leaking? More likely to be a hose. Does water pool under the car when its left standing or are you only losing water when the cars moving?

Thanks for your answer. I haven't seen any obvious leaks, it seems to happen when the car is moving. Do I need to be topping up with anything other than water?
