I have a 91 honda civic. What will I have to take off in order to get the compressor off? Should I go from the top or bottom?

 

both, get the top two bolts from the top and the bottom two bolts from the bottom, this is of course you already loosened and removed the a/c belt...

 

you'll have to go from the top
and if you got freon get it evacuated and if you got no froen just take off the two bolts on the top to get the high and low pressure valves off, then there are 3 screws connecting the bracket
thats it

 

I cannot get to the bottom bolts from the bottom, its got a bracket that goes across that blocks access. And its a very tight fit to be able to get down there from the top. Any suggestions?

 

you need a small wrench
