Look directly across from the radiator and you will see 2 small Hex head screws . (about 6mm). both on top of the engine .. one is one the passenger side at the coolant hose,, the other on the drivers side also at the coolant hose. Loosen the screws until they feel loose, but don't remove them .. start the engine and as the engine begins to warm you will see spurts of coolant come out of the screw threads ,, do not tighten until a nice solid flow comes out (all the air has been purged) .. then tighten but don't over tighten, Make absolutely sure the radiator cap is very tight .. some of these caps have a tendency to only engauge 1 side of the cap and it's not easy to see ... grab the caps firmly and see if it's really tight ,, if not than your engine will overheat in a very short time
