Radweld

[Pete W]

Hi, just wondering what peoples opinions was on radweld. I have got a tiny leak on my rad, and my mechanic advised using some radweld. I've never been a beleiver of the stuff, but was wondering what others thought about it. Any opinions welcome. thanks

you might as well throw eggs into the radiator.

Bars is better...used it plenty of times to great success

Any of the coolant so-called leak additives have a tendency to end up blocking the heater matrix and even some cores of the radiator.

It is OK as a get you home fix but not recommended as a permanent repair. It also gathers in the cooolant galleries inside the engine block and cylinder head.

What may start off as a reasonably cheap radiator could end up expensive in the end.

Ask anyone who has ever had to replace a heater matrix.

In my experience good mechanics just don't recommend the stuff.

Is bars liquid or like an OXO cube, as i've seen some that you crumble like OXO cubes, which i allways think will block the waterways

Bubikal will not block any part of your cooling system.vauxhall and others use it ( or did ) on assembly line. the motor trade have used it for years.cant speak for Radweld etc.

Guess it's a bit of a mixed bag then. Think i'll go with my gut instinct and change radiator.
