I had a minor accident with my s70 and need to replace upfront. My radiator got pushed back a little, but otherwise seems intact. However, it is leaking from the drain plug. When I pour the coolant/water mix it immediately comes out the drain plug. Is there a fitting that need to put on the bottom of the plug? or is does just need to tightened?

Thanks

 

Replace the radiator. It must be cracked or broken.
