For the Toyota Nadia with the 3S-FSE-D4 engine, you can find the fan belt and A/C belt using the following specifications:
1. Fan Belt: - The fan belt for the 3S-FSE-D4 engine should have the following specifications, which you can use to find a replacement: - Part Number: 90916-02400 - Dimensions: 6PK1955 (6 ribs, 1955mm length)
2. A/C Belt: - The A/C belt for the 3S-FSE-D4 engine should have the following specifications: - Part Number: 99364-20840 - Dimensions: 5PK1060 (5 ribs, 1060mm length)
When replacing the belts, it's important to ensure that they are installed with the correct tension to prevent any high pitched noises or premature wear. If the belts are making a high pitched noise, it could indicate either wear or improper tension. It's recommended to inspect the belt tensioner and pulleys for any signs of wear or damage while replacing the belts.
Additionally, it's a good practice to check for any misalignment of the pulleys as this could also cause excessive noise and premature wear on the belts. Once the new belts are installed, check the tension according to the manufacturer's specifications to ensure proper operation and minimize noise. If the noise persists after belt replacement, further inspection of the A/C compressor and other related components may be necessary.
No, you should be able to fish the belt over the fan blades, one at a time. Follow this:
Step 1
Open the hood. Disconnect the negative (black) battery cable.
Step 2
Inspect the fan shroud for the accessory belt routing diagram. If the diagram is missing or illegible, use a pen and paper to draw your own diagram before removing the belt. The new belt must be routed around the pulleys exactly as the old one was.
Step 3
Locate the spring loaded belt tensioner on the front of the engine. There is a small pulley attached to the bottom of the tensioner arm.
Step 4
Slide the square end of the breaker bar into the square hole in front of the tensioner pulley. Rotate the breaker bar counterclockwise and the entire tensioner will move enough to relieve the tension from the belt. Pull the belt out from under the pulley and slowly let the breaker bar retract.
Step 5
Remove the accessory belt from each pulley with your hands. Rotate one of the fan blades to the top side of the engine with your hand and pull the belt around it. Repeat this process until the belt is around all of the fan blades. Pull the belt out of the engine compartment.
Step 6
Route the new belt carefully around each fan blade. Wrap the belt around the crankshaft pulley to begin the belt routing process. Refer back to the belt routing diagram instructions to properly route the new belt around the accessory pulleys.
Step 7
Turn the tensioner counterclockwise again with the breaker bar. Position the new belt evenly under the tensioner pulley. Allow the tensioner pulley to tighten against the belt. Pull the breaker bar out of the tensioner.
Step 8
Reconnect the negative battery cable.
fan belts squeak for several reasons 1 incorrect belt for pulley.2 belt running on the botton of the pulley and worn pulleys. To check measure across the top part of the pulley and the widest part (back) of the belt should be the same if not marginally bigger. V belts work best at t5he top of the pulley.If you can see that the pulley is polished at the bottom the belt is slipping and not driving Check if the pulley sides where the belt runs is not stepped from wear. Recheck the tension as new belts stretch slightly. If you have a multi groove pulley check the tension setting. As a last resort CRC make a product that is used to stop belt but it is best to fix the real fault first
Things You'll Need 3/8-inch drive breaker bar Metric sockets Serpentine belt
1 Open the hood and inspect the flat surface on top of the plastic fan shroud for the belt routing diagram. Follow the diagram instructions to route the new belt.
2 Locate the serpentine belt self-adjusting tensioner on the front of the engine block. The tensioner has a pulley on the bottom of the tensioner arm, which the belt travels under. The tensioner can only be rotated from the bolt that secures the pulley to the tensioner arm.
3 Rotate the tensioner in a clockwise motion with a metric socket and the breaker bar to loosen the tension from the belt. Then, pull the belt off the top of the tensioner pulley. Release the tensioner pulley and pull the breaker bar off the pulley bolt.
4 Pull the belt out of the accessory pulleys. Then, slide the belt around each fan blade and out of the engine bay. Rotate each fan blade to the top side of the engine to get the belt around each fan blade.
5 Match both the new belt and the old belt together to make sure that the new belt is the correct size. Then, route the new belt around each fan blade and around the crankshaft pulley. The crankshaft pulley is the big pulley at the very bottom of the engine.
6 Follow the routing directions from the belt routing diagram to install the new belt around the other accessory pulleys. Once the belt has been routed around all of the pulleys, look over the belt and make sure that it is secure inside all of the pulleys.
7 Crank the 1998 Dodge Caravan and let the motor run for about 15 seconds. This will finish seating the ridges of the new belt into the grooves of each accessory pulley.
It really depends on your engine. If you have the straight 6 cylinder and it's the pulley that bolts to the alternator bracket then it's the idler pulley. If you have a different engine I can tell you.
You can do it. If it takes longer than 10 minutes something is wrong. If its a V8 make sure the tensioner is good, Fan belts rarely just "break" so check all the pulleys.
Look for a decal of some kind for the belts. I take it that your probably have V belts, you mentioned moving the alternator bracket. That's your adjustment so with that all in, it should slip right on. Check and see if there is any other adjustment you can make. If all else fails you can go to a local auto parts store and pickup a manual which I'm positive will have a diagram of some sort in it. Hope this helps!
you dont need remove the fan or the fan shrow you can put the belt on by looping the belt partially on a fan blade and then turnning the fan blade kinda like a bicycle chain and if it is the power steering belt there is a guard over the top of the pulley just remove the 2 10 milimeter bolts and it will come right off
