How to replace tension pulley bearring on a 2000 plymouth neon

remove crank pulley and timing cover. line up timing marks remove tensioner and belt remove pump.

Hi,

A tensioner pulley is used to maintain proper belt tension. Some belt tensioners are locked in place with a bolt or nut after correct adjustment has been made. Other designs use spring tension to automatically tension the belt. Advice: Too much tension will cause a strain on any bearings involved. Not enough tension can lead to slippage or belts jumping off. Tensioner pulley bearings are of the sealed type and can not be serviced. Check to make sure that there is no wobble or play in the bearing and that it turns smoothly. If any play or roughness is found, the tensioner pulley should be replaced. If spring tension is being used, ensure the integrity of the spring

To re;move the pulley you'll need a 'breaker bar' or a long socket wrench. Just slip the correct socket over the bolt and unloosen it. If your Voyager was built in Canada, the nuts and bolts are usually metric. Make certain that you're using the correct size so as not to strip the bolt. It's a pain because of the lack of room. Just take it slow and easy.

No you will not have to pull the motor. The pulley is held on with a standard bolt. However, if the pulley bearing is worn, I would suggest replacing the entire tensioner. The spring inside gets weak over time. It won't cost all that much more for the whole tensioner (it includes a new pulley already installed) and it will prevent a problem in the future.

a serpentine belt tool is really needed to do this. you use the tool to move the tensioner to remove the belt. once you remove the belt there is a bolt in the center of the tensioner not on the pulley but the unit itself. unbolt this and you can remove the old one. the second belt should be replaced if your doing one. here is a picture to aid you. hope this helps

Remove the belt and check all the pullies. the should turn freely and shouldn'have any side to side play. With the exception of the power steering pump, it will pull out alittle this is normal. Also check the tensioner, this should move back and forth smoothly and have the same tension all the way. Some to look at before you remove the belt is the alignment of the belt and pullies. They should be strasight with each other. If one looks like it is leaning it is bad. especially the tensioner. It can lean at the pulley and at the mount

In most cases this would be correct, the belt tensioner bearing failes the pulley goes out of line and that in turn causes the belt to come off.

I usually use a 3/8" breaker bar with a shallow well socket to get them out. They are typically hard to loosen but with the breaker bar it makes it easy.

there are several.4-6 or more?? if the coolant is rusty, plan on doing all of them or sell the car. BIG $$$$...If you have not kept up with the coolant service,you will have much bigger problems later on. how many miles? at 90k miles replace the timing belt, tensioner and water pump, use factory chrysler parts only. if you dont and the belt breaks, or water pump siezes, the engine will be trashed.

Most tensioners have a bolt on the other side of the twnsion pulley, if not you have to replace the tensioner with the base.

the tensioner is part of the engine mount bracket..not serviced seperately as far as i know
