You fill it from the overflow jug located on the passenger side of the engine compartment
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 not one. You just have to loosen the bottom radiator hose and open the fill cap on the antifreeze reservoir when the vehicle is cool.
While cold fill through radiator cap until full, then fill reservoir at front of car to the " cold " or full level.
i got a 1991 grand am it is a 5 speed i need to no where to fill it
about as much it would take to fill ur bun hole
On a 1997 Mercury Grand Marquis : The thread on cap on the engine coolant reservoir is your 16 PSI pressure cap / radiator cap
Open the hood and face the engine. Near the front edge on the left side you'll find the radiator cap. With the palm of your hand, press down and twist counter-clockwise. Top off the coolant and replace the cap.
Uhh, maybe try the dipstick tube
Minimum - 26psi Maximum - 36psi I would fill it to about 31psi.
If you follow the upper radiator hose (the larger hose at the top of the radiator usually below the fill cap) from the radiator to the block you will find a housing that will unbolt from the engine. Your thermostat will be inside this housing.
On a Marauder VZ800 (1998), remove the black cap (triangle shap) on the right side at the front. There you can fill radiator fluid.
First You Would find the drain plug on the left or right of the bottom of the radiator,locate the plug screw the plug out let the fluid drain put the plug back,go to a local parts store get 1 gal. of antifreeze pour that in first, then fill the rest of the radiator with water/check for leaks,no leaks your set for life.
