SOURCE: what is the l shaped hose called that comes from

Heater hose connector is all they call it. I assume you are talking about the hard plastic one,they come as a set(another one in the back too) I know auto zone sells them,others too I would think .
usually on the rack with"help" Problem solvers.They just slip in ,o-ring seals on the ends.Of course you must take the tensioner off.3 bolts(don't forget the bolt holding the tensioner pully on is left hand thread.)

How do I replace heater hose fitting elbow


Tools: 10 mm 13,mm,15,mm sockets and a straight screwdriver if you need to pry, a shop light, you will need to get the air out running a while while you add coolant back to level.It's usually the top elbows that leak, if its the 3800 drain coolant into something, go to AutoZone tell them u need the elbows for the 3800, remove your coolant tank, and your alternator, pretty simple, loosen alternator, then slide belt off, then move alternator out of your way, remove the 3 bolts, pull loose, place in new parts, press back in place, then tighten everything back. Discard your bad elbows with bad seals. Check for leaks, if all good, your done.

2006 pontiac grand prix smells antifreeze in car


Is there coolant leaking inside the car? Check the floor under the passenger side dashboard. If the carpet is wet your heater core is leaking.

If the floor is dry check the coolant elbows going from the block into the automatic belt tensioner. That's inside the engine compartment. They are notorious for leaking. You may not be able to see the leak because it drips onto the block and evaporates. That's what the smell may be.

Search google images for "3800 series 3 coolant elbow" to see the part I am talking about.

The only way to find a coolant leak is to pressurize the cooling system. You can rent a coolant pressure tester from an auto supply store. Pressurize the system and look for leaks. You may have a leaking water pump.

The elbows can be purchased from the dealer. The water pump you can get from an auto supplier. Might as well change the thermostat while you are doing the other repair. Drain the cooling system and refill with fresh dex coolant.

Make sure you bleed all of the air out of the system or the car will overheat.

Need to locate coolant reservoir in 2004 Chevy Impala engine 3800 series 2


The coolant recovery tank is located between the power steering fluid reservoir and the underhood fuse block in the engine compartment on the passenger's side of the vehicle. .

The vehicle must be on a level surface. When your

engine is cold, the coolant level should be at the COLD

mark or a little higher. When your engine is warm,

the level should be up to the HOT mark or a little higher.

Unknown part name or function


I just replaced that tube on a 1997 3800 series 2. The packaging says Heater Hose Fitting. Dorman part #47065. If the engines are as similar as I think, you need to take the belt loose, remove the alternator, and unbolt the idler pulley. The elbow goes between the idler pulley (why the hell does water need to go through the idler pulley?) and the lower intake manifold. The ends are likely to break off when you attempt to remove the elbow. A good flatblade screwdriver and needlenose pliers are your friend.

This is no joke, I can,t fine where my thermostat is in my 1997 merc sable, ,i even followed the top hose back to the engine block


if you follow the "upper" radiator hose from the radiator to the engine it should have a metal piece that bolts to the car ( usually with only 2 bolts) and also the hose is clamped to it. it most likely has a domed shape to an elbow looking piece. take the "upper " radiator hose from where it connects to the engine. remove the bolts that hold this metal piece to the engine that you just took the hose off of. the thermostat "should" be located under this piece. you must take that metal elbow thing off from car to access the thermostat. where it bolts to the engine it most likely will have only 2 bolts and where that connects to the engine will be a gasket and it will be kinda football shaped. a lot of cars will also have a brass flat screw on top of this domed shaped elbow. that will be the give away to that that is where it is. what you do is when the car is running and the coolant starts to get warm, you back out the brass screw a little. this will let the air escape thats trapped and when coolant starts to escape tighten the screw back down. now you have the air out of the system after youve replaced the thermostat. I hope this helps....

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.

Leaking coolant


These plastic elbows (3.8L Engine) do fail. To the best of my knowledge this is a dealer only item, which is not a big deal as the cost is low (in terms of car repair). Remove the alternator to gain access to the elbow. Monitor the coolant level following repair.

As you probably know, don't let the engine run low on coolant as engine damage will follow.

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 .
