timing belt

[sho'noff]

It is time to get another crank position sensor, why not put a timing belt in there while I am getting dirty.
what are some helpful tips for the timing belt, special tools, etc?
should I worry about another tensioner?
I have the basic knowledge on how to replace a timing belt but this one seems a little tricky any help would be welcomed.
233k miles who knows what could go wrong.

Its pretty straight forward. Line up the timing marks on the 2 cam sprockets and the crank sprocket. Loosen the tensioner and remove. Install the new belt by lining up the marks on the belt with the marks on the sprockets.

Be aware which timing belt you buy. The Italian made belts suck namely because they whine and place too much tension on everything. Something isn't correct about them. Cloyes is the only brand that worked properly for me from the get go. No issues with having to go back and release tension or fiddle with it at all. Just use a USA made belt.

Not trying to start an argument about brands but do a search and read up on the issues some here have with timing belts whining and tensioner studs breaking. Guarantee you that they were all Dayco or a name brand that uses Italian sourced belts.

so, there is no scheduled maintenance on the tensioner? I ordered the dayco duralast belt, is that the usa one?

there is a problem with the serpentine belt tensioner as it is in the way of the timing cover. any clues?

No, all the Dayco belts are Italian. Put it on and see what happens. But do know if it starts whining that more than likely it's the belt itself. I don't know why they do it but they do it for some reason. Just follow the manual in regards to install. Make sure you rotate the whole assembly like it says to do before finally tightening down the nut.

Good idea to replace the tensioner because of the bearing. MTX cars use a spring to set tension and then the tensioner is locked into place with a nut. ATX cars use a hydraulic tensioner.

no manual here, I am now stuck on the crank bolt, the impact wrench is going to have to do or else!! it's not that I can put it in gear and hold it that way due to the auto trans.

Starter bump will break the bolt loose whether its MTX or ATX. SHOphoenix steps you thru it.

impact wrench did not work but just as you said the starter bump got it. it appears the intake valves need a serious adjustment, either that or the timing was off due to the crank position sensor.

true or false; the timing belt tensioner only needs to be tightened and loosened with the bolt. if so what is the torque? gütentight?

ok, I just now put up the tools, the middle valve cover broke the rest of the way during reinstallation. I found the waterpump gasket was leaking but I loosened and retorqued the bolts. I also had to curse at the neighbors dog because it was barking at the birds for a good 45 minutes and they will not quit chirping. tomorrow I will reinstall the serpantine belt and whatever else is left.
(any good ideas for grease in a busted knuckle besides soap and water?)

The waterpump leaking is what caused your crank sensor to fail. If you do not replace the waterpump and waterpump gaskets now, you will be replacing the crank sensor again very soon. Going thru all that effort and not replacing the pump while you can would be a timely and costly mistake.

The intake gets dirty inside because of the pcv system. If you dont want the inside to get like that then you need to install a catch can.
