Small Downturn spout on firewall dumps coolant within minutes

I have a 1997 Pontiac Grand Am SE 2.4. It recently just dumped all the coolant while I was driving. I pulled over at a gas station and looked in the engine compartment. There is a small rubber "L" shaped tube, or downspout on the firewall on the passenger side just below the rack and pinion. It was POURING out Coolant at a ridiculous rate. It's not leaking int the car, its not leaking at the water pump or at the send a receive hoses for the heater, Just the little down tube. What could the issue be? All the auto zones say water pump and the mechanic said Freeze plug, but he wasn't sure. What should I do here?

Both brain sturgeons are wrong. Your heater core is leaking and the coolant is coming out of the heater box where the condensation from the a/c usually exits.

    Yes...disconnect both heater hoses and install a short piece of copper plumbing pipe into both ends of them, secure with clamps. (real pain to get in there but it will work. Likely you will need a manual to get core out later...lots of plastic to remove before you get in there.

Richard's answer is correct. My mechanic used to say that when they build some cars, they start with a heater core and put everything around it. meaning that it's a bear to change. My 1986 Grand Am was like that. Not sure how a 2002 GA is like.

95 VW Jetta dumped all the antifreeze, what could be the problem?

If its coming from the reservoir lid, something is causing overheat. Most likely fans are not working. You can test the fans themselves by pulling the plug off of the sensor about midway up the drivers side of the radiator. short the 2 similar contacts and both fans should come on low speed. short right contacts and they should come on high. if this works your fans themselves are good. look at the fan relay (mounted with 2 bolts under the reservoir) or the temp sensor itself.

How do to install a coolant sensor in a 1997 Pontiac

Yes it usually screws in. Depending on it's location you may have to drain the radiator and save your coolant to re-use. Most of the time it's high on the engine so you don't lose much coolant.

My 1997 Pontiac Grand Prix GTP has an oil leak located on the firewall side of the engine. It's a small leak (2-3 drops a day) but very messy on my concrete driveway. How can I fix it?

Try some motor honey. It can be bought at most part stores, advanced auto, autozone, ect. It worked for my 95 Grand Am when I had a leak in my oil pan gasket. Hope this helps

Where is the a/c drain line on a 95 Grand Prix SE

On the bottom of the A/C evaporator box. This case is located under the hood R/R area. To clear the drain you must be UNDER THE CAR. will probably abe a small hole in the plastic casing clogged and blocking the water. Poke this hole GENTLY to clear, lest you damage the A/C EVAPORATIOR. Hope this helps.
