I am in the process of replacing my tension assembly in my 1996 Camaro (also a 3800 V6). I haven't got it all apart yet, but I did buy a factory replacement part from O'Reilly's today. From what I can see from looking at the new part, you must remove your alternator first. At that point, you'll see that the tension assembly is a fairly large piece that is only held on by a few bolts. Toward the top, it forms one of the mounts that the alternator attaches to, and toward the bottow, it curves back out and has a couple of rubber hoses attached to it. I haven't figured out where the hoses go to exactly, but they look fairly easy to remove.
The thing that really threw me off is that I thought you had to have some sort of special tool to remove the tension assembly. I thought that just the tension pulley (black plastic wheel) and the arm that it attaches to was the assembly, but it's actually a big piece that attaches with a few bolts.
Well, I hope this points you in the right direction. Just remember, remove the alternator first and you'll see how big the assembly actually is.
If its like my Buick Regal (98) there are 2 bolts holding the tensioner on. Remove those bolts (2 1/2 in or so) and it will seem like something else holds it on. It will be loose yet won't come off. Since coolant flows through the tensioner it has to go back into the engine. You have to take a prybar and gently pop it off the engine. There are (2) passages in the tensioner. One is a 90 degree plastic elbow that goes into the intake manifold. This will break when you pry it off. The other passage slips into the water pump. There is an o-ring in there, do not forget to change it. The elbow is called a heater core bypass elbow, your parts store should have it. You will have to use a seal pick to get the old pieces out. Clean the passages out with a rag, spray silicone on the new stuff and it should slip in easily. Also I would suggest if it hasn't been done yet, R@R the lower and upper intake manifold gaskets and get the Dexcool antifreeze out of the motor. Trust me on this, it will save you a ruined engine. Good luck.
Here is a diagram that shows the whole assembly. I am planning on replacing one of the elbow O rings on our Chevy impala because it is leaking, hope it goes smoothly! Thanks for posting your experience.
How do you remove the headlight assembly on a 2001 camaro?"
One bolt holds the tensioner to the engine, take it off to get the tensioner off and then you can get to the bolt that holds the pulley to the tensioner.
Remove the serpentine belt. Tensioner is below Alternator. Remove the three mounting bolts on the tensioner baracket assembly. Replace entire unit.
The 1998 Lincoln Continental belt tensioner assembly is held in place by three retaining bolts. Remove the retaining bolts. The belt tensioner will come off.
remove belt then remove two bolts holding it on and remove old put new one on
Remove the Right wheel and inner plastic fender which will allow you access to the tensioner side of the motor. There will be a few bolts holding into place on the block. Remove the bolts and remove the entire tensioner assembly. Reverse for replacement.
remove radiator assembly/ disconnect all bolts/ lift it from top
remove wheel. remove brake caliper assembly(not the brake hose) and pull off the rotor.
Put a ratchet on the tensioner pulley bolt... set your ratchet on "loosen" turn the tensioner pulley and assembly upword... hold it there and remove the belt... DO NOT LET GO OF THE RATCHET AFTER YOU REMOVE THE BELT slowly let the tensioner pulley move back to a resting position...
Just remove the bolt that holds it to the front of the engine and take it off.
Remove belt and tensioner complete should be able to be unbolted from engine (Left-hand thread)
remove interior panel and unscrew large black plastic nuts, remove light assembly
You have to remove the tensioner assembly, not just the tensioner pulley, but the whole assembly, in order to access the plastic bypass hose. Be very careful, as these pipes get old, the plastic becomes brittle, and possibly the flange end will break off and remain in the block when you remove the pipe, check the block opening carefully to remove all of the remaining flange. Also, be very careful when removing the lover pipe nipple into the engine block, if you try to pry the tensioner assembly off the block, you will probably snap off the machined nipple that locates into the block, Ask me how I know!!! Good Luck, it can be done but you need to move carefully and deliberately. (by the way, a rebuilt tensioner assembly costs about $80 US, the pipe is about $6. New tensioner assembly comes with the pipe)
most places sell the complete hub assembly. You have to remove the brake assembly there are four bolts holding the hub assembly in place remove and reinstall
rotate the tensioner clockwise to release the tension and remove the belt then slowly release the tensioner. route new belt over the various pulleys according to the diagram under the hood again rotating the tensioner as to allow belt to fit in place and then slowly release the tensioner again.
How to replace the tensioner assembly depends on which engine your car has. If it is the 2.5L 4cylinder engine: 1. The tensioner assembly covers a coolant opening in the block, so you need to drain the coolant to point lower than the bottom of the tensioner assembly. 2. Release the tension on the serpentine belt and move the belt out of the way. 3. The tensioner assembly also is the mounting point for the power steering pump. So to change the tensioner assembly first remove the power steering pump. Be careful to avoid power steering fluid leakage. 4. With the power steering pump off, the tensioner assembly is held onto the block with three screws, remove them. 5. At this point the tensioner assembly should simply pull off. It may be stuck to the block with rtv sealant. Install the new tensioner: 1. Clean the old sealant off of the block. Be sure to have an adequate bead of rtv on the block or the tensioner to seal against coolant leaks. The last time I replaced one of these there was no mounting gasket, it was all done with just rtv sealant. 2. Mount the new tensioner and tighten the bolts. 3. Reattach the power steering pump. Check the fluid level, refill if necessary. 4. Reinstall the serpentine belt. 5. Top off coolant as necessary, check for leaks. If your car has the 2.8L V6: 1. Release the tension and remove the serpentine belt. 2. The tensioner assembly is held on by one bolt in the middle of the fixed end. Remove the bolt. 3. Install the new tensioner assembly. be sure it is in the correct rotation. Tighten the bolt. 4. Put the serpentine belt back on. You are done.
On driver side, you will have to remove the steering assembly. With the passenger side you should only have to remove the factory manifold.
Remove the belt, Remove one bolt out of the fulcrum part of the tensioner and remove the tensioner; reverse the precedure.
Loosen 13mm nut that secures tension pulley. Then loosen 13mm nut/bolt just above tensioner assembly facing upwards, to remove tension from belt. Then finally remove the three 10mm bolts holding tensioner assembly to engine block. Install in reverse order.
loosen the tensioner bracket, remove old belt. replace with new belt. tighten with tensioner. job complete!
You will need to loosen the tensioner pulley. Slide the tensioner pulley to the right and the serpentine belt will become loose. Remove the old serpentine belt and put the new serpentine belt on. Slide the tensioner pulley to the left and tighten it.
raise the trunk. pull back the carpeting. remove the 5 plastic wingnuts holding the light assembly in. separate the light assembly from the car. twist and remove the bulb. installation is reverse.
remove belt, remove upper accessory tensioner bolt (shock) remove bolts holding power steering pump and push to side - to get at recessed tensioner bolt. remove lower a/c bracket - front of engine. Remove tensioner bolts and tensioner.
Remove the serpentine belt and remove the alternator. The belt tensioner bolts are under the alternator.
You will have to replace the complete window regulator assembly.
