Timing belt pulley bolt won't come off!, Help please :-) Options

[wilc4]

I have a 1996 Celica GTS Convertible with a 2.2. I need to replace the water pump and to do that need to remove the timing belt (arrgh!!!). I got it to to TDC and have good access to the 3/4" bolt and am using an impact wrench but still cannot get the bolt to come off. My impact wrench just goes and goes and my concern is that it is actually starting to round the bolt.

Any suggestions on how to get this thing off?

Thanks!

Hah, I just had to do this myself...took me about 4 days to get it off.

I didn't use an impact gun, and the engine was out of the car when I did it. On a stand.

I used a breaker bar, with another 4-5 foot pole on top of it. Then I used one of the flywheel bolts to hold the crank in place with a pry bar to stop it from moving.

Came off pretty easy once I got the torgue in the right place.

Don't know anything about that holding "hole" on the 5s, but on the 3s, those holes are ment to pull the pulley off, not the bolt. So you may not be getting a solid crank as you estimated. Trying holding it from the flywheel side somehow, or use a breakbar longenough to bump start it with the starter.
