You don't have a cap on the radiator. The cap is located directly on the coolant bottle
bottom of radiator

On the coolant overflow bottle
On the plastic overflow bottle
theres no cap on radiator~ it is filled through the recovery tank on the fender well.
there may not be one if there is is it on the bottom side and if it is not you candrain it by removing the bottom rad hose The 1999 Pontiac Grand Am does not have a radiator drain valve. To drain the radiator, remove the lower radiator hose. The engine should be cold and the water fill cap removed for venting. I have a 2000 Pontiac Grand AM and radiator drain cock is located at the lower/front (not bottom) at the curbside of the radiator, you will need a hex key to back out petcock. .
There is no radiator cap. The cap is on the coolant resivuar bottle on the passenger side under the hood next to the firewall
You can find the radiator cap for a 95 Grand Am at various auto parts stores. You can also find replacements through Pontiac dealerships.
The thread on cap on the engine coolant reservoir is the pressure cap / radiator cap for the engine cooling system
Its located on the radiator passanger side about 3" below the radiator cap.
I am not trying to sound stupid, this is my question. There is a radiator cap and the overflow bottle as well, but the cap only turns slightly but will not lift off, and before I break something I just want to know that it will come off.
Add the coolant into the coolant reservoir. Be sure the engine is cool when you remove the cap off the reservoir.
