Had the belts break and come off engine, top center pulley damage
1991 ford escort gt 1.8L
the pulley from the engine that turns the alternator/belt is damaged and came off. what is that one called, and after replacing that how difficult
is it to replace the drive belts? engine sits sideways under hood so belts run front to back on the passenger side of vehicle.
Re: had the belts break and come off engine, top center...
The belt that turns the alternator is called the serpentine belt. this also usually runs your fan and is sometimes also called an "accessory belt"
If you look down at the belt area, you will see a pully toward the front of the car that looks like it's attached to an arm. That is the tensioner pully. The tensioner is spring loaded. If you look at the arm of the tensioner there should be a square hole in it to insert a socket wrench or a breaker bar/pull handle to use as a lever to remove the tension from the belt. If there is no hle, then use a wrench(possibly 15mm) on the bolt head of the pully itself as your lever. As you hold the tensioner out of the way, unloop the old belt. Pay attention to the routing, so you can reinstall the new one correctly. Then, you route the new one in and again use your lever to move the tensioner so you can get the belt over the last pully. I usually put it over the alternator last. Use a light to make sure the belt is fully on all 5 grooves of every single pulley before you start the car.

Rotate the engine until the Timing mark on the Crankshaft pulley, is in line with the Timing mark on the Bottom casing.
Rotate the camshaft pulley until that Timing mark is in line with the Mark on the Camshaft bearing casting.
Install the timing Belt from the RH side, with no looseness in the Straight line tension, depress the Tensioner pulley, and feed the belt around the Water pump drive, and then the tensioner.
As you release the tension on the Tensioner pulley, ENSURE that neither of the Timing Pulleys MOVE.
Rotate the engine 2 times and check that the Timing marks at Top Dead Center are still ALIGNED.
If all is in good order, reinstall the Motor Mount and Belt covers and ancillaries.
Locate the serpentine belt tensioner on the front of the engine. The belt tensioner on the 2001 Ford Escort is located directly under the power steering pump and above the air conditioner pump. The belt tensioner has a 17 mm bolt head in the center of the pulley.
The tensioner is between the a/c compressor and crank pulley, below the power steering pump. Use a 13 mm wrench to 'tighten' the bolt in the center of the pulley and it'll move to release tension off the belt.
first jack up the right front tire side of your car and remove cover under your car motor, so you can see your pulleys from underneath your car, remove black cover where your timing chain belt is thats on the top center between alternator and powersteering pulleys, ok,looking at all your pulleys from your right side of your front end, starting from your top left is your alternator pulley,put belt on it and go underneath the motor mount to your right top powersteering pulley,then go down around the bottom right ac pulley,then to your left bottom crankshaft pulley,the back side of the belt thats on your top alternator pulley wraps around the soft edge pulley thats above your center waterpump pulley,then wrap around the idler pulley that's under your top alternator pulley,then wrap the backside of your remaining belt around the tensioner pulley that's in on your right, under your top ac pulley, use a 13 mm wrench to adjust by turning towards the back of your car so you can slide the belt on
First put the car up on jackstands, remove the front left wheel. disconnect battery, take the drive belt off, remove the drive belt tensioner, put a floor jack under the engine with a block of wood or somthing to support it, remove the motor mount by taking the 3 bolts off of the body and the bolt out of the center of the mount. Remove the crankshaft pulley, this may require a pry bar. Take the bolts out of the front cover and remove it. Take the timing belt tensioner loose by loosening the 10mm bolt and rotating the tensioner with a hex key. remove the timing belt. I would also replace the tensioner while I was in there. Line the cam and crank up with the index marks, the cam has a pointer on the sprocket that lines up with a dimple behind the pulley. The crank has a keyway that lines up with a mark on the block. Install the timing belt and tension it making sure the marks do not move, then rotate the engine by hand 2 revolutions and make sure the marks line up again. After that reinstall everything in the order you removed it and fire it up. -Jared
