You put a 3/8" ratchet in the tensioner arm. Looking at the side of the engine to the passenger side of the van, the tensioner is at the top of the engine towards the back. Twist the tensioner to allow the old belt to be removed, Install the new belt following the same path. There should be a sticker on the belt guard by the power steering pump. The belt will fit smoothly on all the pulleys. Pay attentions as some pulleys have the belt groves facing in, some have the belt groves facing out.IMPORTANT - When you do this, put all the keys for the car in your pocket so no one can try to start it.

10.5 quarts or basically 2.5 gallons

1: Drain coolant system
2: Purchase coolant flush, making sure you have the proper amount for your size of coolant system
3: Pour coolant flush into your radiator, filling the rest with water
4: On the coolant flush bottle it will tell you how long to run your vehicle
5: Once done running, let cool enough to open radiator cap, and drain system COMPLETELY by first draining out of pep **** on radiator, then taking one side of the hoses off the radiator and draining those
6: Put hoses back on and fill system with coolant. When the fluid gets to the top of the fill port on radiator, start vehicle and let run, allowing air to escape the system, and fill as necessary

Depends on how bad the head gaskets are. I've used it on numerous vehicles motors, and if the problem was minor, it worked. If the problem is a little more than minor, it would be a wast of money trying to treat it, you would be better off replacing the gaskets.

Instructions

1. • Detach the negative battery cable from the battery of the Pontiac Montana with an open end wrench and move the cable so that it is not touching any metal objects.
   • 2Locate the alternator in the front of the engine on the passenger side of the engine compartment. The alternator will be on the top, side of the engine with a belt running to the crankshaft pulley.
   • 3Unfasten the electrical wire connector from the alternator by using a socket wrench to undo the nut and take the electrical wire connector off the terminal.
   • 4Loosen the bolts holding the alternator in place with a socket wrench just enough so that you can move the alternator on the bracket, and take the alternator belt off the pulley. Note: Do not remove the belt from the crankshaft pulley.
   • 5Undo both bolts on the alternator with a socket wrench until you can remove the bolts completely and take the alternator out of the bracket, removing it entirely from the engine compartment.
   • 6Position the new alternator in the bracket and slide the bolts back into place, tightening the bolts with a socket wrench until you can just barely slide the alternator on the bracket.
   • 7Place the alternator belt around the alternator pulley and check the position of the belt around both the crankshaft and alternator pulleys to verify that it is seated properly.
   • 8Place a crow bar between the alternator and engine block and pull back on the alternator with the bar to add tension to the belt.
   • 9Tighten the bolts on the alternator with a socket wrench while you keep the tension on the alternator belt.
   • 10Reattach the electrical wire connector to the alternator terminal by placing the connector and the nut on the terminal and securing with a socket wrench.
   • 11Connect the negative battery cable to the battery of the Pontiac Montana with an open end wrench.

replace thermostat .

Check Fuses. There is a seperate fuse for the cig lighter and the power port. Hope this helps. Thanks

Missing is usually ignition problemsBackfiring-timing issues or possibly lackof fuelRepeated dead battery that is over 4 years oldyou have to replace.I would first change the spark plugs & thensuspect a timing chain issueJust have to go over the entire engine, one itemat a timeYou can not just shot gun the problem or expectan internet guessThe vehicle has to be looked at & things tested

Check for low coolant in resavoir if coolant is not low then replace the coolant level sensor.

REMOVAL: 1) Remove the plastic belt routing diagram (there is a bolt underneath if I remember correctly)(yep, 8mm). 2) Using a 3/8 breaker bar or a ratchet, insert into the belt tensioner and push toward the back of the engine enough to release tension on the belt with one hand, and with the other hand, remove the belt from the water pump pulley. Then remove the bar/ratchet from the tensioner. 3) Remove the 4 bolts holding the shiny pulley onto the water pump (11mm). 3a) Large catchpan underneath, there's more coolant in there than it looks like. 4) With a ratchet and possibly a short extension, carefully remove the 5 bolts that hold the water pump onto the block (8mm). 5) Pry the water pump away from the block and clean both surfaces so they are free of gasket material. INSTALL: 1) Line up the gasket and *carefully* fit the new water pump onto the block. The holes are very easy to line up wrong because they are almost, but not quite, equally spaced from each other, so be VERY careful you have all 5 holes lined up right. 2) Screw each bolt in a few tuns to make sure they all go in smoothly. If you get any resistance (it will feel like it's crossthreaded), you have the holes wrong, and you need to rotate the water pump so the holes are lined up right. I can't stress this enough. 3) Torque all the bolts down (I can't recall the exact in/lbs - sorry) in a star pattern. 4) Mount the pulley onto the water pump shaft, torque bolts down (an air ratchet helps greatly here as the shaft will try to spin when the bolts start getting tight). 5) Release the tension as explained in step 2 at the top, put the belt back on the water pump pulley & double check to make sure it's on all the other pulleys while you're at it. 6) Bolt the plastic bolt routing diagram back onto the head. 7) Refill the resevoir and bleed the system of air. That's it! It's an hour or so job if you've never done it before. Note, if you're not using a gasket, get some water pump gasket sealer and make a gasket around the entire diameter of the mounting surface of the water pump. Remember to make little circles around the bolt holes also.

some one added it is a flush port get new hose and remove it before it cracks and leaks.
