How to remove tensioner pulley??

The title says it all. Im trying to remove the blower and the stupid tensioner pulley and those two bolts behind it are the only things left to remove. What tool do i need to use to get the bolt on the pulley because there is barely any clearance. Thanks in advance

Mike

you can either use a regular wrench and angle it a litte, but your might strip the nut.

or a flare nut wrench will do the job.

something like this: http://mgaguru.com/mgtech/tools/flare_nut_wrench.htm

it should be a 14mm wrench

Thanks alot. I really appreciate it

Now here's another question. How do i adjust the belt tension while the blower is on or is it a trial and error type of thing??

use a 10" extension along with the universal swivel adapter. make sure the tensioner pulley nut is loose before you adjust your belt tension.

what two bolts? the allen bolt behind the IDLER pulley? if so, you want to be careful with that or your will strip it. dont air tool it. make sure your allen key socket fit in completely. then turn your wrench. try a breaker bar or larger wrench but never air tool an allen bolt.

what's the other one?

a pic will help

if you can post a pic i can suggest a way to get it off. i have removed and installed my kit over ten times now. i have never needed any air tools to get anything on or off. i can usually remove the blower and reinstall it in just over 2 hrs. to change belts or pulleys. later.

Look at the picture on page 63. I took the tensioner pulley (red/black) off and am working on the bolts that hold the gold plate thing on which the tensioner is mounted to the block. Now that I look at that picture, it seems that those bolts arent even necessary to take off. Oh well you live and you learn. So i guess the only bolts left are the one behind the idler pully(#18) and the one on the alternator(#17) (pg. 62).

Any suggestions on how to get alternator bolt off?? Should I take off the lower radiator hose?? And what tool to use?

bolts on the top

to remove the 1 on top of the tensioner pulley you have to remove the sc bracket. the one bolt is covered by the sc bracket right where the other idler pulley sits(the second plactic one). the other one i think can be removed once you pull the tensioner bolt out of the tensioner bracket. i stopped using the one bolt behind the ilder pulley because it made installing and remove the sc or changing the belts easier. lok at page 61 and you can see the tensioner bracket move clearly. there are only three bolts that hold it in place. hope this helps. later.

Im not trying to remove the tensioner bolt itself. Im just trying to remove the SC bracket. My question is do I have to remove the tensioner bracket to remove the SC bracket, or can i leave it in place?

And what did you do to remove the alternator bolt? I REALLY dont wanna have to remove the radiator hose.

nope, no need to remove the tensioner bracket.

no need to remove the radiator hose either. if you have a set of gear wrench, you will be able to slide it in between the mounting brakcet and the water hose. if not, have someone puse the water hose from the top of the car while you are loosening the bolt from bottom.

The only two bolts that are a truly pain in ther rear should be the one ten mm directly under the plate and the allen FHS thats behind the idler pulley. If you can stick an air tool up under the plate I paypal you $100. The tensioner pulley, grab a 14mm open/closed end wrench and turn it and remove the tensioner pulley. Then proceed to get a 19mm open/close end wrench to remove the idler. After you have the idler pulley out, from under the car grab a 5mm allen wrench and remove that FHCS. Careful not to strip that FHCS or the plate will not come off. If you strip it, I have a box full of them.


I highly recommend you drive to NAPA and invest in some gear wrenches.

OK will do. Thanks for all the help guys.

BTW, what is the exact size of the bolt that goes into the alternator?

Ok so i got the alternator bolt off. Only the allen bolt behind the idler pulley to go.

But removing the idler pulley with a combination wrench?? There's no way. There has to be some other tool i could use...

crawl up under the car, grab a 19mm gear wrench and turn the bolt. Use the closed end of the wrench to spin that 19mm bolt off. You can also use a craftsman wrench. I prefer the flat gear wrench like this one because they make the job easier.

I appreciate the help but i dont see how anything can get around that bolt. It basically sits flush with the pulley so unless someone develops a wrench shaped like an "S" i dont see it coming off. It's like trying to play hockey with a baseball bat. Stillen is for putting that stupid allen bolt behind the idler pulley. However i get the idler pulley off, i know im leaving that allen bolt off for sure next time.

if you use that gear wrench your right is not going to sit flush. You can get some of it on there and turn it. This is all patience. Ask anyone that has seen me take this off. I take it off in 5 mins or less. **** the wrench at an angle and it will turn that bolt. I would not leave that allen bolt off. You do that and you may have alignment problems.

what i did for that is to loosed the idler pulley bolt as far as it can go with an open ended wrench and then with the allen key, loosen it that way.

i had to cut my allen key with a dremel so it would fit.

Man i dont know what else to do. I have the correct tool for this. Im using a 19mm gear wrench on the idler bolt but the problem is that i cant get it free in the first place. I can apply torque to it but it doesnt seem like it's enough. And when i apply TOOO much pressure it slips off. And my left hand is getting all cut up from hitting the A/C compressor pulley when the wrench slips off. What else can i do?

I went in from the bottom to avoid taking off the lower radiator hose. Why?

Edit: I'm pretty sure that the top half of the idler bolt is rounded. I guess the only other thing i can do is take the radiator hose out and have at it from the top. If that doesn't work what are my options?

you stripped the 19mm??

use a flare nut wrench and try again. usually I use a regular wrench and slide it in from an angle and loose it a little first. then use the gear wrench to remove it.

Ahhh...I finally got the 19mm out with the gear wrench. I took the lower radiator hose and got to it from up top. But I'm gonna get a new 19mm bolt since this one is rounded pretty good.

Should i anti-seize or thread-lock anything putting it back together?
