If you have a book picture your are screwed. You do have a tensioner but it is between air con and powersteering pullys. In front from under you can put 15mm wrenchopend with a nother for leverage pull center bolt down to release tension. simple.

SOURCE: serpentine belt slips off idler pulley

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.

SOURCE: how do you release tension on idler pulley to

There should be another pulley that looks like the idler pulley but is located just a little further down in the serpentine pulley system. This is the tensioner. Use a wrench or a shallow well socket to crank it to gain slack and slide the belt off the uppermost most easily accessible pulley. The tensioner will probably pivot toward the rear of the vehicle so you'll want to crank it toward the front of the vehicle (if the serpentine belt assembly is on your driver's side, reverse this).

Do I need special tools to change water pump on 2005 cadillac cts

  1. You'll need a tool to release the tension on the serpentine belt and when you need to put the belt back on. Regular standard socket wrenches will suffice for the rest.

Serpentine belt was shredding and smoke was coming from under the hood. changed the serpintine belt and it si still smioking

Serpentine belts have an idler pulley and an automatic belt tensioner - either one of these could have gone bad and could cause the smoke. The idler pulley has a bearing inside that can seize, stopping the pulley from turning which would cause the belt to fray. The tensioner keeps the belt tight and when they go, the belt hangs loose, causing the belt to burn on the other components. The Alternator also runs on that belt, as well as the a/c compressor and other components, depending on the particulars of your car ( make, model, engine, accessories, etc.) and the main bearings can be bad there too. There are actually several key components running off the belt and, without being there, I cannot accurately diagnose the issue. I recommend you go to a reputable shop. The type of smell in the burning would guide me to what to check - there are many things that can cause these symptoms. If that mechanic only changed the belt but did not investigate the cause I personally would not go back there.
I'm sorry i couldn't offer anything more concrete to help - hopefully I've given you some directions to look!
Hope this helps!!

Will an idler pulley cause the car to smoke and leak coolant or oil

Not likely. Idler pulleys are only for routing of the serpentine belt. If one of your "pulleys" is leaking coolant its likely the water pump, which also has a pulley on it. The smoke is probably leaking coolant burning off a hot part of the engine or exhaust system.

Replace the serpetine belt

My sincere apologies for the severly delayed response.
I am personally going back to answer your unanswered questions.

I do not know if you still need this information, however I am answering it in case you still do.

Click on the following direct Link. It has A Diagram for your Belt.


Standard Rules to Removal the Serpentine Belt with a Tensioner:
1. Find the Tensioner(s). (See Diagram on Link)
2. Using a Serpentine Belt Tensioner Tool, Or Wrench OR Ratchet, Rotate/Move the Tensioner USING THE AVAILABLE NUT (on the Pulley or Arm Base) OR the OPENING (3/8ths or 1/2 inch square opening) rotating it\moving it away from contact with the belt and towards the area where the belt is not in contact with the Tensioner Pulley. The Tensioner is spring loaded, and is hard to rotate/move.
3. Remove the loosened belt off one of the other more easily accessed Pulleys.


Standard Rules for Installing the Serpentine Belt with Tensioners:
a. Pick a Pulley that is most easily accessed. This will usually be on top. This will be the last Pulley that the belt will go on.
b. Using the Diagram: Install the new Serpentine Belt on the remainder of the Pulleys....over, under, left right.
c. Using a Serpentine Belt Tensioner Tool or Wrench or Ratchet Tool: Rotate/Move the Tensioner Pulley/Arm "away" from Belt contact area on the Tensioner. This spring is pretty hard and with a new belt, it will be even harder to install. Rotate/Move this to as-close to the maximum allowed inorder to have enough slack in the belt to get it up and over the last pulley.
d. Using your other hand - Pull the Belt up and over the Last remaining Pulley.
e. Before releasing the pressure on the Tensioner, visually inspect the remainder Pulleys and the Belts' Positioning on them

Again my apologies...
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.Com!
