What engine? If it is the 3.1 v-6, the air in the cooling system has to be bled out. There are 2 bleed points, one on top of the water line for the heater (which is the black tube that comes out of the top just above the water pump) and the other is at the upper radiator hose inlet on the thermostat housing (some models have a silver tube from this one to the coolant tank. If it has the tube, you only need to bleed from the first point.). The fittings are 7 mm and slotted screw. Get the engine warm with the cap off, and open the bleed screw(s) until all the air is vented. Then shut the engine off, top up the coolant and install the cap
