SOURCE: 1996 Buick Regal Sport - Leaking Plastic Elbow

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.
STEPS:
-REMOVE BELT
-DISCONNECT BATTERY
-DRAIN ANTIFREEZ AND DISCARD
-REMOVE ALTERNATOR
-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 .

SOURCE: Hose from water pump to intake manifold above and behind water pu

this is a water pump bypass hose connector to the manifold, take the broken piece to a parts store and show it to them, it should have the threads still broken off in the manifold so explain that. To remove the broken piece ask for a EZ OUT to fit the piece you took to the store.
It is common for these to become brittle and break off but it is a simple fix.

SOURCE: lower intake manifold gasket leaking 02 Olds Silhouette

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

How do you change a heater line elbow on a 2004 Pontiac Grand Prix ?


This must be a 3.8 liter engine. They have 2 plastic elbows that always break they run threw the alternator mounting bracket. #1 disconnect battery #2 remove serpentine belt by unloading tensioner . #3 remove alternator and mounting bracket this needs to be pried away from cylinder head remove broken pieces and clean passage bores install new elbows with some vasoline on o-rings and align then reassemble. one elbow comes from intake manifold both sides are the same size the other comes from timing cover near water pump the lager side goes into timing cover.

My 2003 monte carlo ss is leaking antifreeze. i noticed it is leaking from behind the belt tensioner out of a piece which is black in color and has a 90 degree angle on it.


There are two plastic elbows that go from the intake and the waterpump to the tensioner bracket for the heater hoses. They need replaced.

I have a 98 Olds Intrigue. It is leaking coolant and water from somwhere on the passenger side of the motor. Replaced water pump and radiator is fine. Any ideas?


Depending on what engine you have, the 3.8 has a plastic elbow coming out of the lower intake manifold that goes to the belt tensioner assembly, which has 2 hoses coming out of it for the heater hoses. That elbow likes to crack. The older 3.8 has a nipple there which also likes to crack that runs to the heater core. Either way that's where i'd be checking first.

I have a water leak coming from my engine block. How to repair 2001 Buick 3.8 It is come out of a 5/8 pipe or around it


If it's a hose, best bet is to just replace it, and use new clamps.

If it's leaking where it's connected to the nipple, for a quick fix, you can remove the hose, cut the hose off past the leak, and reattach it.

This requires a little bit of slack in the hose, but if the leak is right at the connection, there should be enough slack in the hose to do this.

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!!!
