Did this video help you?

Don Dyzzle: I have a 1997 Subaru outback legacy I recently noticed that the engine gets real loud when in isle than calms down for two minutes the gets loud again what does this mean?

614yeloboi702: hello, besides the idle pulley, would the ignition coil have anything to do with the screeching noise at start-up? and before trying to replace the pulley, is there a way that i can look at it while being started to determine if it is indeed the pulley, thanku n advance!!!

1A Auto Parts: @surfndude44 It wouldn't be a bad idea if it's the original one. If your truck also has the original water pump, you may want to replace that too while you're in there, and already have it off. Here's a link to our timing chain sets on the website if you would like to check them out. 1aauto.com/1A/TimingBelts/Ford/Explorer/-/-/2002?utm_source=youtube&utm_medium=youtube&utm_campaign=1ATony

Jonathan Neal: When i changed my Idler pulley & tensioner pulley on my 2002 explorer i didn't disconnect my battery .i never do unless i have to last time i did it messed up my engine idle made me go nuts didn't know what was wrong with my explorer it always wanted to almost stall at a stop but reading info online i disconnected the battery again for 15 to 20 minutes fixed it

1A Auto Parts: Thanks for watching. 1aauto.com 888-844-3393 FREE SHIPPING on all auto parts in the lower 48 states!!!

1A Auto Parts: @tiara313 They're pretty easy to fix. We sell the pulley on our website 1aauto.com If you have basic hand tools it's not to bad to fix yourself. Hope this helps you out.

1A Auto Parts: You may want to inspect the other pulleys to see if they're working correctly.

1A Auto Parts: You may be referring to the AC compressor pulley.

powers0099: I have a 2005 ford taurus. It is making a whirring noise coming from the pulleys. I have replaced the tensioner pulley and it is still making the noise. What else could it be. It is a 6 cyl. Thanks for any help.

1A Auto Parts: @567dirt8910 If the belt squeals when you start the truck up, it should either be a bad belt on your Ford Explorer or a worn serpentine belt tensioner. I would inspect the ribbed side of the belt first for cracks. If it has a bunch of small cracks throughout the belt you should change it. If it's not cracked, more than likely the belt tensioner needs to be replaced. Hope this helps you out.

TheKing0fHalo: I think I'm going to have to do this soon, do I need to replace the bolt, washer, and bushing too or should they be fine? Thanks.

1A Auto Parts: @surfndude44 There's not really any trick other than trying to narrow down what section of the motor the noise if coming from while it's running.

jpedroza602: I got a 5.0 started squeeking aftervchanhing water pump i changed belt and pullis and still aqueeks i wonder if my new water pump can be squeeking....

567dirt8910: I think this will be my next move on my 03 sport trac. The "belt" or one of the pullys squeals bad in wet weather, Is this a sign of something particular??? I guess I'll just remove the belt and test the idler pully out and see what needs to be done. I'm sure I'm due for a new belt also. As always thanks for the videos - I love 'em.

Vinicius Pietscher: Great video, that was exactaly what I was looking for! I need to replace the same pulley for my explorer but I couldn't find it in your website for the 94 model, can you please help me? And I live in Brazil, do you take international orders? Many thanks!

surfndude44: Thanks for a great video. I have a 2002 Explorer and have this squeak and replaced the belt tensioner but still have the noise. The serpentine belt is not glazed or cracked. The noise begins a few minutes after the engine is running. It sounds like it could be the idler pulley. Is there a trick to determine exactly where the noise is coming from ?

Jarad Nobles: Thanks for this video. I lost my idler pulley earlier this week and had to replace it. This video helped me confirm my suspicions and quickly repair my vehicle. DIY definitely beats taking it to a shop when it's something simple like this. Thanks again guys!

614yeloboi702: the belt looks fine, tension feels good as well, if i look at the idle pulley while some1 starts my car if there any way visible to know that the idle pulley is failing? and thanku for taking time to respond

99f234: thanks, this video helped remind me how to install the idler pulley on my 2002 ford ranger today. thumbs up.

journalwriter: the idler on my 94 mazda pick up b4000 seems to be different from the one shown on the video...the one you replaced.... looks like a hockey puck mine looks like a small tire rim...does it matter?

surfndude44: Hi.. thanks for the response. I have one more question. My 2002 expolorer has 148K miles. Is there any service that needs to be done with regards to the timing chain?

1A Auto Parts: It could be the fan making noise, you may want to look at it. Hope this helps you out. Have a great day! 1aauto.com 888-844-3393

1A Auto Parts: The procedure should be pretty much the same.

1A Auto Parts: We carry them for both the 4.0 and 5.0 motor. If you call we can take your info over the phone and match you up with the correct serpentine belt for your Ford Explorer. 1aauto.com 888-844-3393

614yeloboi702: thanks again, i removed the serpentine belt, all pulleys r tight and spin upon touching, except for my power steering pulley it moves a bit, so i figure i need to replace the whole thing considering when making a turn my steering column sticks(resist) sometimes. but as far as the short noise n engine knock at start-up, it has completely died. now it makes a noise (maybe grinding) and wont turn over at all. im lost, n dont have cash for the shop.

1A Auto Parts: You may want to check the belt to see if it's worn or cracked. You may also want to check the belt tensioner to see if there's enough tension on the belt.

Evan Last: Is the tension pulley in the same spot on the 5.0's?

1A Auto Parts: @journalwriter It sounds like you have v belts on your '94. Obviously you want to make sure you get the correct replacement and removing the belt probably involves loosening a pulley or component.

1A Auto Parts: @xx0rz Hey thanks for checking us out. Glad we could help you out. Have a great day!

ogbobbye: Love your videos every time I need to do anything on my car I check your videos first. the idler pully look easy to do but I still watch this first and glad I did cause I didnt know about that lock washer on the back side. BTW I had to change a bad oil pressure sensor switch and I was surprised you didnt have a video on that because its a pretty common problem on Fords it was easy to do but very hard to figure out how to get at it. I know you would have had a trick or 2 to get it. thanks

Steven Oak: Thank you for a great video showing exactly what needs to be done to replace the idler pulley

1A Auto Parts: It may be the belt tensioner that's loosing some of it's tension. When you did the pump you had to lift up on the tensioner to release the tension on the belt. This may be what's causing the noise. I had this happen on a 92 Mustang when changing an alternator, If it is, we sell new serpentine belt tensioners with free shipping on our website 1aauto.com 888-844-3393

DJTommy812: my bolt broke off my 1999 ford explorer xls 4.0. any idea what size it is and where to find buy it? please message me ASAP if possible thank you

1A Auto Parts: usually if a tensioner or idler pulley fails they'll wobble all over the place.

kevin suber: I was struggling with replacing the drive belt for my 96 explorer and found your instruction video, as soon as I finished the video it only took me 5minutes! Started my engine and the Idler sheared off. I guess I should have checked my pulleys hahaha. Watching your video on replacing Idler. Got to get the old bolt out first. I will always check with your site before starting my next project! Thanks
