Water pump leak.. need advice
Why I think it started... When changing my oil last week I noticed the coolant was low. Well, the little coolant that was on the dip stick looked green to me, so without thinking, I added some green coolant/water I had in the garage.
I realized the mistake I made when the coolant dripping from the water pump had a orange/pink tint (Dex Cool). I then confirmed that the car is suppose to take Dex Cool in the manual
. I would have normally made sure but I couldve sworn the little coolant that was on the stick was green. Anyways, I ran the car for just a few minutes today to see if I could see the leak again, no leak, but it also didnt get very hot at all.
Sorry this was long, but, what do you guys think? New pump? Or maybe just try complete flush and fill first and see if its still leaking? Anyone else made this mistake, and care to admit it? Anyone have a good pump laying around they would sell?
I would use this as a great time to do a nice cleaning/flush job on the system. I outlined a pretty good process for it in this thread (post #19)...

There's more information on page 2 about cleaning out the overflow tank and such. Hope this helps!
I also noticed, that night it was leaking pretty good, it was only when the engine was off. I think when it was on, it created a vacuum and didnt leak.
