Well, there are two place is can go. In the radiator and the reservoir. The radiator is the big black thing in the very front of the engine area. It usually has a silver cap. DO NOT OPEN THIS CAP WHEN VEHICLE IS HOT OR OVERHEATING, DANGEROUS...it says that on the cap too. If you are not good with pouring, then get a spout and put it into the radiator after you open it and pour the coolant in slowly. Watch for it to rise so as not to overfill. You also put the coolant in the reservoir this is usually a white plasitci container on one side of the fender area that says, coolant only. You can put water in there but far less effective than coolant. Do the same thing with the spout if needed and only fill to the lind indicated on reservoir.
how to remove a engine in a 1999 Pontiac grand prix 3.8L
why does the coolant only leak when engine is off on my 1999 grand am?
The coolant bleeder valve should be on the front passenger side of the engine. It will be on one of the metal hoses. The bleeder valve on the 3400 V6 engine is located on a black stem where the water pump connects to the engine block.
Depends on the parts

The radiator on a 1999 Pontiac Grand Prix is flushed by draining the coolant, filling the system with water, adding a liquid flush to the system, and running it for a few minutes. The system is then drained, flushed with fresh water, and refilled with coolant.

Why wouldn't it? There is NO difference between a 1999 and a 2000, as of right this second i have a 1999 Pontiac grand am with a 3.4 liter (what your looking at right now) and built it from ground up. I know plenty about cars.
You don't have a cap on the radiator. The cap is located directly on the coolant bottle
loosing coolant without leaking under the car, so it is burning coolant, mine is staying on and so is engine light and it is also a 99 grand am gt and just happened today :( now we to put upper gaskets in.
