I have a 2010 Subaru Outback that I bought second hand. The first few weeks it was fine, but then suddenly a bunch of lights were flashing on the dash.

So I replaced the thermostat and did a full coolant flush. A few weeks later, the coolant levels were low again and I realized there was a leak coming from the bottom of the radiator. A few drops per hour.

I tried to use radiator leak stop to no avail.

Then I tried to patch up the bottom of the radiator using metallic paste

But it still drips. It’s not an urgent issue, the car runs fine and I top off the coolant once a month. But it’s annoying and the car always smell like coolant.

Any ideas on a fix? How hard/expensive would a full radiator swap be?

    Radiator replacement can be pretty simple. You can possibly remove the rad and take it to a rad shop and have them repair it for fairly cheap, however you can probably also find a relatively cheap new aftermarket rad. If I was you I’d flush that rad leak stop out as soon as possible because that shit is snake oil and will only cause you headaches in the long run.
