Trying to be optimistic as to whether I should view the radiator as half full or half empty...LOL. So I noticed a small puddle the other day. Opened the hood and the reservoir was almost empty. After driving home form work the radiator cap was still cold. Thought that was odd. Opened it, and no coolant. The radiator was warmer about halfway down so I assume there was some in there. I'm getting it fixed. I think its a hose because I see dry residue around the passenger side. So long as there was some fluid in the radiator, should I be ok?
