Im looking to change the serpentine belt ,but i heard about a tensioner that they have ,where is located in the engine,and if i have to tight againg have the new belt is installed?

Tensioner is hydraulic and is self adjusting.

After further research have the dealer look up TSB EG021-07. The belt tensioner was updated with a new assy. because of noise. TSB dated 4-17-07.

Engine Mechanical problem
2003 Toyota Corolla Front Wheel Drive Automatic

I want to remove the plastic cover on the top of the engine of my 03 Corolla. There are two acorn nuts, and two plastic fasteners. To avoid braking the plastic fasteners, I want to know if there is a correct method of removal? The reason for remomoval of the cover is to give myself some extra room to replace the serpentine belt.

They are flimsy at best, I took mine off and replaced with M6 x 1 studs and nuts, available at most hardware stores.

I am needing a diagram to replace the serpentine belt in my car

time to replace the drive belt (it is showing wear). I have a manuel on how and am a retired mechanic so should be no issue. The pboblem is the tool to loosen then retighten the belt. it is a unfamiliar size and shape. looks like a torx. tried a e16 and e18 but neither will fit. talked to a mechanic at toyota that said use a 19 but unable to locate.

can you help

Is it an E torx (female) or T torx (male)?

Toyota does use a lot of 12pt bolts, which do look like an e torx.

There is no E19, he may be referring to a 19mm 12 pt.

Toyota Corolla 2003, 64k

A Toyota dealer recently changed my serpentine belt. They got my authorization by claiming the belt was cracked. It was not. But now they claim that the belt was 'glazed, slipping and wearing unevenly'.

Some questions.
-- Can a belt be slipping given I never heard a sound?
-- If it is slipping, are there any other 'signs' other than noise?
-- What does a glazed belt look like (a pointer to where I might find a picture of a glazed belt would be nice)? This belt flexes well and no part looks different to the rest.
-- What would 'wearing unevenly' mean? The only wear I can see is minor wear (normal :?: ) on the side of the belt. By this I mean that on some parts you can see stiching as though it's new, in some areas you see the rubber (stitching has faded or been worn).
-- what makes belt replacement 'necessary'?


P.S. The belt was just under 8000 miles on it. When I examined the belt they had left in my car, I assumed that they had misinterpreted my instructions and left a new belt :!:
Belt was replaced at 57k after intermittent noise that disappeared after a couple of minutes - belt was diagnosed as glazed back then.

Serpentine belt wear is one of the most misunderstood problems on a vehicle. Everything depends on temperature, engine performance (smooth running) and condition of the pulleys. A belt can look new and still have thick and thin spots.

A good rule of thumb is to replace the tensioner and the belt. The spring loaded action of the tensioner causes thick and thin places.

Flip the belt over at various locations and if there are more than 3 cracks per inch replace it. The last rule is ALWAYS replace the belt between 45,000 and 60,000 miles. It will save a lot of problems.

Lastly DON"T buy a belt from discount supply houses. Get a quality belt and replace the tensioner at the same time. It is a small expense to save a very expensive repair.

Good luck

that series 03 on up thru at least 05 have a reputation for noise when starting cold. usiually it,s related to the tensioner malfunctioning. sometimes it,s just the belt. alot of discusssion how to replace the tensioner all over the web.

Four cylinder front wheel drive automatic.

Released the tension-er by turning the tension-er clockwise. what shall i pay attention to avoid any potential mess up?

After that, how to put back the tension-er? just turn the tension-er nut counter-clockwise, to the original position?

Where is the forum the answers will be posted?

Thanks,


kk

Both on and off pull clockwise. See diagram.

I am replacing the Serpentine Belt in my 2002 Corolla. The Auto place that is doing this for me will charge me the same labor for multiple belts if I need to have more than 1 put on. What other belts are in my car that I may need to have replaced?

Only have one belt

Hi MALAKIYA, Here are the procedures. FAN AND GENERATOR V BELT (1ZZ-FE) REPLACEMENT 1. REMOVE ENGINE UNDER COVER RH 2. REMOVE FAN AND GENERATOR V BELT a. Turn the drive belt tensioner clockwise to relieve tension on the belt, and then remove the belt. b. Carefully return the tensioner to the unloaded position. NOTE: Be sure to connect SST and the tools so that they are inline when using. When retracting the tensioner, turn it clockwise slowly in 3 sec. or more. Be sure to not apply force rapidly. After the tensioner is retracted all the way, do not apply force any more than necessary.

Hello,
I am very new to car repairs and have found your website extremely helpful. I saw the video about changing the drive belt on your website. My toyota is different, it doesn't have a spring loaded tensioner that i can see; should I change the belt trhu the alternator?

Hi jangtex,

For some models you need to unloosen the adjusting bolt at the alternator to remove/replace the belt.

how do i get the new belt back on the engine? i would also like to know if i can get a diagram for the tension bar and how to get the belt on right?

My TOYOTA COROLLA 2000 CE is making rattling noise. It is coming from down under the hood. When I turn the steering wheel the noise goes away. Some times the noise goes away magically for no reason. I showed my car to a mechanic, they asked me to change the serpentine belt, which I did but the noise is still there. They also changed the pulley but the noise is still there...
Other mechanic said that it might be timing chain. Somebody else said that A.C. compressor has problems but my A.C. works fine (it blows cold air). I am confused, could you guys please help me?

if you changed the belt you shold have changed the tensioner as well. you can still do that. but disconnect the belt and seeif noise disappears. if it does then its 'internal to engine.

Noises problem
2001 Toyota Corolla 4 cyl 77500 miles
----------------------------------------------------------------
Hello,

Great to find this portal in the internet. I am facing noise issue with my toyota corolla 2001 model having milege of 77500. Though it is not very loud but when I asked my toyota dealer he told me to change the engine belt as it is getting loose which creates noise. He did not say that it isurgent but warned me that it might break anytime.

Please let me know what exactly could be the problem and if possible, pls provide me more description about the belt he is talking about.

Thanks

He must be talking about the serpentine belt since the 1ZZFE engine is equipped with a timing chain, not a timing belt.

The serpentine belt could be bad or the tensioner bad.

I would go ahead and change the serpentine belt and tensioner. If it breaks you will lose the AC, alternator, power steering etc.
