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 .

That drain line is for the box that holds the air conditioner evaporator and the heater coil. It seems that your heater coil has sprung a leak and the leaked fluid is coming out the drain. You have to replace the heater coil, which on most cars involves removing a lot of the interior equipment, including the dash board on many cars. A job best left for the repair shop unless you're very adventurous and patient. Even then you will have to take it to a shop to have the air conditioning system recharged.

This is a 3100, or a 3400 V6 engine? It should be one of the water hoses that connects the tube on the front to the water pump, it is a preformed hose availiable from many parts stores and is not difficult to replace, if you drain a little coolant out before you take it off you will lose less coolant in replacement, be sure to refill coolant after your done. Hope this helps, let me know

You are correct it is connected with two plastic elbows the will almost always break when you remove the assem. If you have removed all the bolts you should be able to wiggle and work it loose by gently prying on it, just look at the direction of the elbows and work it in that direction, but i highly reccomend replacing both elbows.

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.

3100 engine antifreeze leaking from area under a


  • There is 1 or 2 elbows (plastic from factory) that connect the coolant channels from the engine block to the tensioner pulley housing. Mine only had one (in front, visible and disintegrated) and in the back, the pulley housing had a nipple (cast) that had o rings and was inserted into the back coolant hole in the block.
  • You need to make sure to remove all bolts holding the tensioner housing on.
  • Swivel and/or wiggle the pulley housing off very slowly so as not to break that nipple off of the pulley housing.
  • The parts stores only sell the elbows in 2 packs, but they do have metal instead of the original plastic.

My 98 buick regal looses coolant I have recently flushed system out, replaced water pump & thermostat but my I keep loosing coolant dont see any leaks i will fill it up & in a couple of days its...


Take look down by the belt tensioner. There are two by-pass tubes that run from the tensioner to the engine. The by-pass elbows have rubber seals on them and after the coolant flush may have damaged or ruined the seals.
The only other option is the coolant is going into the engine oil or transmission oil. Check both oils and see if they look "milky"
Good luck.

Plastic L shaped hose next to serpentine belt and altenator is cracked and antifreeze leaks out of it. How difficult is this to replace and what is the part called???


That is the coolant inlet elbow for your alternator bracket/tensioner pulley assembly, very easy to fix.

Just let the motor cool off first and have more coolant handy.
