I have a leak in the bottom left hand corner of my radiator as you face the front of the car. I need to put about ½ litre of coolant/water mix in every 3 weeks or so. I’m nearly sure I have to replace the radiator as the leak is quite noticeable along where the plastic and metal meets. Its like the metal has corroded and I can see the fluid forming at the bottom of the rad.
My question is do I need to replace the radiator or is there anything that can be done to save the existing one?
