How do you change the water pump on a 1996 dodge avenger?
GOOD LUCK WITH THIS ONE,ITS A REAL TUFF JOB IF YOU DONT HAVE THE PROPER EQUIPMENT BUT IT CAN BE DONE IF YOUR A GOOD BACKYARD MECHANIC. FIRST OF ALL JACK THE CAR UP AND REMOVE THE PASSENGER SIDE TIRE , PUT JACK STAND UNDER THAT SIDE. UNBOLT THE AIR POLUTION PUMP FROM THE FRONT OF THE ENGINE AND PULL AWAY BUT DONT DISCONECT. UNBOLT AND REMOVE THE SIDE ENGINE MOUNT, THIS IS WHERE IT GETS HARD. PUT A JACK UNDER THE ENGINE AND JACK IT UP AS HIGH AS YOU CAN GET IT THE WIGGLE THE ENGINE MOUNT AND BOLTS OUT, THEY WILL COME BUT NOT EASILY. NOW GO AND RENT A CRANK SHAFT PULLY PULLER OR HARMONIC SINCRONISER , GO TO AUTO ZONE YOU PUT A DEPOSIT DOWN AND GET IT ALL BACK. PULL OFF THE CRANK SHAFT PULLY AND REACH UP BEHIND THE ALTERNATOR AND LOSEN THE TENSION BOLT , THIS ONE IS FUN TO BUT AGAIN IT CAN BE DONE. REMOVE THE ALTERNATOR AND AIR CONDITIONING BELTS FROM THE PULLY THEN POP IT OFF. NOW REMOVE THE PLASTIC SHROUD, TWO BOLTS ON BOTTOM . YOU CAN SEE THE WATER PUMP NOW BUT IT LOOKS LIKE THE REAR SHOUD ALSO HAS TO BE REMOVED. FORGET IT , JUST CACK ENOUGH OF IT AWAY SO YOU CAN GET OUT ALL THE BOLTS. THERE YA GO, NOW PUT IT ALL BACK TOGETHER, AND MAKE DAM SURE YOU HAVE THE CRANK SHAFT PULLY TIGHTENED DOWN AS FAR AS IT WILL GO OTHERWISE THE BELTS WILL SLIP OFF. YOU WILL PROBABLY JACK UP AND LET DOWN THE ENGINE AS FAR AS IT WILL GO SEVERAL TIMES BEFORE YOUR DONE.
You can go to Auto Zone.com and check under repair info, and it will give you instructions and illustrations on how to do it. I must tell you, it is a lot of work. A mechanic will charge you up to 1k dollars to do it. If you replace the timing belt make sure you change the water pump and idler pulleys also.
I had the same problem with a 1996 Dodge Avenger 4-cylinder manual transmission and found out that is was the Idle Air Control Motor is located right underneath the Throttle position sensor. It will run as long as a revved the engine but as soon as I would let go of the gas pedal it would not idle and it would shut-off.
