Check the water pump and the heater hoses. Also check the radiator and the engine for cracks in the block or leaking freeze plugs. You just have to keep looking. Park it on a dry patch of pavement and idle it until you see coolant dripping then look directly above the puddle!

It could be leaking over a hose or metal part and running down, which throws u off cause the poodle won't be directly under the leak

Look around the intake manifold as well. Unfortunately these engines are known for developing leaks as has already been mentioned. While its good to figure out what's leaking, fixing the leak is not always viable on an old car like yours (and mine). My standard advice after making sure its not a leaking hose or radiator is a couple of cans of Bars Leak. Its a safe, cheap and often effective way of taking care of the problem for the balance of the car's life without spending hundreds of dollars on it. "Fixed " the leaky intake manifold on mine 5 years ago without taking anything apart, and so far, so good.

The lower in take manifold always goes bad and people donr even know that the super charger takes its own oil and has to be changed every 30000 miles iys organic super charger oil and there is nothing on the market that mimics it
