    Question Radiator leak

    Noticed that my car was gettting a bit hot yesterday so I pulled up at a garage to find that my car was just throwing loads of water out from underneath the radiator. Managed to fix it with some of that radiator repair fluid which seems to be holding it ok.

    Would the cause of this have been down to a faulty thermostat may be, if so what will I need to do?

    You'll need to give us more info on the car (model, age, mileage, etc). Are you sure it's not just failed? Radiators don't last forever. That repair stuff is not great, and is certainly not a permenant fix. If I were you I'd get it checked out and the radiator replaced if necessary.

    So is this a garage job then, nothing I can do myself with the help of a Haynes?

    Assuming that it's the original radiator, then I would bet that it's failed. Mine lasted 110,000 miles, so yours has done well.

    Changing the radiator is not too tricky. You just need to remove the bumper, disconnect the existing one, fit a new one and then refill with coolant. At a guess I'd say to budget around £80 - £100 for a new radiator.

    What about any hoses, will they need replacing as well?

    if its a direct replacement and the hoses have not perished then its a straight swap. or take the opportunity to upgrade to one of the ebay alloy numbers

    ebay ones do the trick, but there a ball ache to fit so they line up correctly, just a heads up if you do decide to get one
