I have a 87 grand national antifreeze is leaking from the bottom what is wrong.....I know nothing about cars

First off, kick ass car! Is it leaking from the radiator, the hose(s) or the engine?

Is it a big leak (the whole front end of the car has anti-freeze under it) or a small leak (the size of a basket ball or smaller)? Is it leaking out now or only when the car is running?

I went in the house after I started it to let her warm up 10 mins later came back the freeze was on the floor leaking when I stopped the car it just drips

Thanks Tom. Could be just the water pump itself, very common on the older GM cars. If you know nothing about cars, 87grand, get it to a REPUTABLE mechanic.

Oh yes they where and are. VERY cool car and in the best color you can get, black. They made a T-Type Regal with the turbo motor as well. Not nearly as much $$$. I almost pulled the trigger on an 89 Indy pace car turbo T/A. They only made like 1550 of them. All white with the Grand Nat turbo 3.8 in them. FAST really FAST I think it was the fastest T/A ever produced if I'm not mistaken.
