(This answer Covers the Ford Motor Company Ford Taurus and Mercury Sable with the 3.0L OHV "Vulcan" Engine and the 3.0L DOHC "Duratec" engines.)Installation notes:Replace the belt by fitting it around the pulleys and lastly loosening the tension with the tensioner/idler pulley to allow the belt to fit over the last pulley. Attach a 15mm socket or wrench to the bolt in the middle of the tensioner pulley.On all 3.0L (OHV) engines, rotate the drive belt tensioner clockwise to relieve belt tension and slide the belt off the pulleys.On 3.0L (DOHC) engines, rotate the tensioner counter-clockwise to relieve belt tension and slide the belt off the pulleys.Replace the belt by fitting it around the pulleys and lastly loosening the tension with the tensioner/idler pulley to allow the belt to fit over the last pulley.AnswerPut a wrench on the (spring loaded) tensioner/ider pulley and take out the tension. You can then remove the belt. Replace the belt by fitting it around the pulleys and lastly loosening the tension with the tensioner/idler pulley to allow the belt to fit over the last pulley.
use breaker bar with square drive in the square hole. takes 2 people to do safely, as belt is under a lot of tension A further suggestion. I use an 18" long, 1" (id) black iron pipe as an extension for my breaker bar. It makes a world of difference and one person can then de-tension the belt and slip the belt over the alternator pulley.
Hey Chris==Pull up on the belt and you can see how the idler puller must move to release tension on the belt. The schematic for the belt should be on the fan shroud. If it isn't, draw a schematic before removing the old belt. Don't rely on memory. Goodluck Joe A further suggestion. The belt tensioner uses a 1/2" breaker bar to de-tension the serpentine belt. I still had problems releasing the tension, so I used an 18" long, 1" (id) black iron pipe as an extension for my breaker bar. It makes a world of difference and one person can then de-tension the belt and remove or reinstall the belt over the alternator pulley.
I assume that this is a petrol engined Mondeo The Mondeo's idle speed is controled by a sealed air system Most erattic idling problems are caused by an air leak somewhere in the system.
The battery should be disconnected. The belt tensioner is spring loaded, using a socket and wrench, pull to the side to release the tension. Remove the old belt. Install the new belt over the pulleys the same direction that the old one went. Release tensioner and reconnect the battery.
The tensioner does not need removing. It just needs to be swung out (clockwise) of the way to reduce the tension on the belt so the belt can slip over the pulleys. The tensioner has a slot, towards its end, for a 3/8 drive in it. Place the drive into that slot and you get the leverage to overcome the tension in the spring.
open the hood-youll see the tension pully with the belt wraped around it and to the other pullies. youll need the right socket wrench to loosen the belt once accomplished-youll turn the nut on the pully to remove-go slowly and check the direction if correct. remove the tension pully insert the new one-put the screw back in=dont over tighten then place the belt back on-start your engine.
very simple, there is only one belt , a serpatene belt, and you use a 10 inch ratchet and short socket head to release the tension on the tension pulley, it is only going to go one way, the belt slips off, there is a diagram on the front shroud, in front of the radiator, that shows the belts direction around the pulleys, just slip this around and then pull back on the tension pulley, slip the belt over the last pulley located at the top, ( easier to get to ) and then release.Addition: If he has a 1999 4-cylinder Ranger, he has a timing belt. This is not the same as a serpentine belt and it takes more than just a ratchet handle to change it.
Using a ratchet and socket, put the socket on the bolt holding the idler pulley to the tensioner arm. Pull the ratchet and the whole assembly will swivel over taking tension off of the. The belt can now be removed. Reverse the process to put on new belt. This is easier done with two people.
If its a 4.6 1992 to newer. You should be able to read the belt label over the alternator then route it RIBS to RIBS and Smooth side to Smooth side. Use a 1/2 drive ratchet or breaker bar on the tensioner pulley to slack the old belt to remove and install the new one.
can use a breaker bar with either 3/8" or 1/2" inch drive, whichever fits in square hole. be careful, because that belt tensioner is under a lot of force. You really need 2 people, one to release the belt tension and another to remove/install the belt A further suggestion. I use an 18" long, 1" (id) black iron pipe as an extension for my breaker bar. It makes a world of difference and one person can then de-tension the belt and slip the belt over the alternator pulley.
Loosen the bolts on the pump to allow the belt to lose tension. Remove the belt, then put on the new belt. Pull the pump to tighten the belt snug but not over tight while tightening the bolts.
