I got my 30K done at Smart Service a few weeks ago. I haven't had any issues with leaking coolant, but I read about the conditioner in the other threads (like the Cooling FAQ) and everyone says you HAVE to use this even if you don't have a recall vehicle.

I've talked to Smart Service, Carter, Chaplins, and SOA and they all said it wasn't necessary.
I'm not really sure what to do. It's like $1 something for the conditioner, so why not? But at the same time, I don't want to have something go wrong and have the dealers say its my fault for adding it - I heard it has to be added directly to the radiator? I'm not really familiar with the cooling system.
Thanks for any help.
