That hose is to let the condensed water out of the box(from the AC system) If antifreeze is coming out there ,has to be a leak in the heater core. Hose is supposed to just direct the water to the ground,open on the end.

SOURCE: How do you change out a heater hose elbow in a

If you are talking about the 90 degree plastic elbow coming from the belt tensioner housing.......first loosen the belt and take it off ( remember the routing on it) and then remove the two little nuts holding the coolant overflow bottle ( you don't have to disconnect the hose....just set it over to the side so you will have room to work). Next remove the bolts holding the alternator and set it to the side.Now the fun part. remove the 4 bolts holding the belt tensioner housing to the block. Once those are out you can pull the assembly forward and the elbows should come with it. The elbows are held in by o-rings and should just pull out. remember to replace both of the 90 degree elbows at the same time ( might as well so you don't have to do it all over again). Assembly is just the reverse of the above. FYI these elbows break so often that you can now buy replacement ones made of metal at www.rockauto.com and they are only $4 more than the plastic ones. I replaced these 5 times before I'd had enough and went searching. Seems that this piece of plastic breaks quite frequently when the vehicle hits a dip at speed.Hope this helps.

How to remove belt tensioner on a 2002 buick regal l s 3.8l


disconnect battery first, unbolt alternator(3 bolts), cross bar bracket(2 nuts) unhook both heater hoses out of the connectors(each has a 7mm head bolt in them, then twist loose), remove belt, then there are 3 bolts holding it on the motor, has a plastic elbow to the intake and an o-ring seal male port that goes into the timing cover. gently pry back and forth to work it loose so not to break either the elbow or the port off. alot of times it seizes up in there. the elbow is a hat trick to get in and out also, just be patient and take your time

I own a 2004 Buick Rendezvous, its a 3.4 liter engine and it's leaking coolant from an elbow on the engine firewall, on the passenger side. It only happens when the heater or the a/c is on. Would you...


That elbow goes to the heater core. Just go to a auto parts store, and ask them for a new elbow, remove and replace and everything will be just fine. The heater core controls the heat and cooling for the cabin of the vehicle.

Is there any fluid leaking onto the floor of the passenger side of the vehicle?

1997 Cirrus is still overheating... The heater does not blow out hot air...would the heater core cause the vehicle to overheat? if not, what other problems am I looking for, I was loosing anti freeze...


it appears that you have a large air pocket/low on coolant. The engine is getting hot due to the lack of coolant but there is no heat because nothing is flowing through the core.

How do you change out a heater hose elbow in a 2005 buick lacrosse


cool car down and drain the radiator, usually a spigot or valve at the bottom. remove the clips or clamps holding the hose on, pull hose off. get a new hose from any parts store, sometime helps to have the old one with you. install new one, put on new clamps and tighten firmly, pour in new coolant. check your owners manual to see what kind of coolant Buick recommends.

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.

How do I install the heater hose outlet located above the water pump. The part is plastic, 90 degree elbow.


You have to take the intake off in order to change..Its threaded in and the only wall to thread it in is remove intake.It wont screw in with the intake on because the elbow is to big and will hit block when you try to turn it..Have a great after noon..

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 .
