YOU NEED TO REPLACE THE BELT TENSIONER.
IF YOU BUY THE CARTER BELT TENSIONER AT ADVANCED AUTO, IT COMES WITH: A PLASTIC ELBOW WITH O RINGS, TENSIONER, PULLEY, NEW O RING WHERE THE BELT TENSIONER MATES TO THE ENGINE BLOCK AND NEW O RINGS FOR THE INLET AND OUTLET CONNECTIONS ON THE BELT TENSIONER TO THE HEATER CORE (COST $72).
IF YOU DON'T REPLACE ALL THE ABOVE O RINGS THEN YOU CAN EXPECT MORE LEAKS.
IN ORDER TO REPLACE THE PLASTIC ELBOW YOU MUST REMOVE THE BELT TENSIONER ANYWAY. IF THE BELT HAS SEVERE CRACKS REPLACE IT ALSO.
-DRAIN ANTIFREEZ AND DISCARD
-REMOVE BELT TENSIONER
-REMOVE PLASTIC ELBOW (DO NOT ALLOW BROKEN PIECES PLASTIC OR DIRT TO GET INSIDE THE ENGINE WATER CAVITIES.
-CLEAN ALL CONNECTION WHERE O RING WILL MATE.
-TO REASSEMBLE GO IN REVERS ORDER
-REFILL THE RADIATOR WITH COOLENT 50% MIX USE THE 5 YR GUARANTEE TYPE.
-MAKE SURE THE COOLENT RESERVIOR IS
FILLED TO THE HOT LEVEL MARK.
-RUN THE ENGINE UNTILE IT IT REACHES THE 1/4 % TEMP MARK ON THE TEMPERATURE GAUGE THEN TURN THE ENGINE OFF AND OPEN THE BLEED SCREW ON TOP OF THE THERMOSTAT HOUSING.
ALLOW THE AIR TO EVACUATE, YOU WILL SEE COOLENT COME OUT THEN CLOSE THE BLEED SCREW.
-BE VERY CAREFUL WHEN YOU OPEN THE RADIATOR TO REFILL TO THE TOP.
-REPEAT THIS ONE MORE TIME.
-RUN THE ENGINE AND KEEP YOUR EYE ON THE TEMPERATURE GAUGE' IF THE TEMPERATURE GOES BEYOND THE 1/2% MARK, SHUT DOWN THE ENGINE QUICKLEY AND LET THE ENGINE COOL.
THIS MAY TAKE HOURS TO COOL DOWN BUT THE COOLING SYSTEM WILL TURN FROM PRESSURIZED TO VACUUM AND DRAW COOLENT FROM THE RESERVOIR TO REFILL THE SYSTEM.
YOU WILL NOTICE THE LEVEL DROP IN THE RESERVOIR .

Yeah on that vehicle there is a 90 degree plastic elbow that goes from the belt tensioner to the intake manifold and on both ends there are O-rings. Definitely need to repair this as soon as possible. Not sure your technical abilities but you would need to remove the serpentine belt and alternator and a bracket if I'm not mistaken. Usually takes me about 45 minutes to repair but I have been doing it for awhile. Good luck and Happy wrenching!!!

Visit the autozone.com website and register the car information. It doesn't cost anything and you will have access to an online repair manual for the car. The steps for replacing the water pump should be available there. It's a handy resource. Hope this helped and best wishes.
