Does anyone know how bad this is and what it may be? Pink fluid on garage floor. Thanks.

 

Total radiator failure not far away.

Denso 221-3125

 

Yep, there is the beginning of separation between the plastic end caps and metal core of the radiator. It is a common failure point on higher mileage 470's. Failure will be coming VERY soon. Order the Denso OEM replacement (I found mine on Amazon) and swap that out. It is not a hard repair if you are mechanically inclined. Just have to remove the fan shroud (fan also if you want to make it very easy). Check your radiator hoses to see if they still are good and pliable (I am at 212K on original radiator hoses and they are soft and supple still with no bulges).
