Cam install - AC condensor

OK working on cam install, all the guides i have read simply say to "slide the condensor up out of the way."

First off, wont i have to drain all the freon, or can you loosen the fitting and slide the condensor up?

And as far as the fuel line disconnect tool, do you absolutely need one of these?

Last off, anyone have any suggestions on getting the crank pulley off the shaft? I removed the 3 bolts and it wont budge, tried putting a puller on it, but i cant get it to pull straight out...


Thanks

No you don't have to drain the freon. At least on my car I was able to just tilt it out of the way enough to pull the cam right out from under it. Remember tilt it carefully with the lines connected.

I didn't have a fuel line disconnect tool. Once I removed as much as possible from the intake I was able to work the fuel rails with injectors still mounted out from around the wiring harness and from behind the intake manifold. Try to remove the stuff from the back of the intake manifold as well...it will make it easier to work the fuel rails from around the back...not much room, be careful.

Hmm...I had a hard time with the crank pulley and hub as well. I just tapped it out and used my cheapy harbor freight puller to pull the hub out...I may be wrong though, its been a while since I pulled the hub out.

Did you have to loosen any of the AC fittings or did you just tip it up?

I'd suggest going to rent the fuel line disconnect tool. It made my life a lot easier. It was free to rent at my local Autozone, just had to leave a $10 deposit, and I get it back.

If you want to disconnect the fuel lines, you must use a tool. I would rather do that, than fiddle with all the injectors.

Also IMO, if you open any of the a/c lines, you might as well just disconnect the condenser and pull it out. You would then have to take it to get it evacuated and recharged when you have everything back together. The whole purpose of only moving it out of the way is so you don't have to discharge the refrigerant.

Here is how you can use a puller to get the pulley off.

Just take the fuel rail off. It's only 4 bolts.

As for the pulley if it has never been taken off you might want to tap it lightly with a hammer to loosen it from the hub, then use the puller.

It just tips up as far as I can remember. Don't loosen any of the fittings for the AC condensor...oh but I think you have to unbolt the aluminum bottle (forgot what its called) from the car. Its only one bolt holding it to the body of the car. The reason you need to unbolt it is so that you can tip the condensor over with the lines still attached to the "bottle" without breaking the lines. Sorry its hard to explain but I'm trying my best.

This is the guide I use just in case you don't have it:
