mmm yaaa ... i did the same thing on my 91 civic HB ... your in for a real f***ing nightmare on that ...
your SUPPOSED to remove the pully on bottum to get the cover off ...
supposed to .. i cheated ... cut the bloody f***ing thing ... its a b***h .....
the pully can be a real pain in the ass to get off , i never could break it so i had to take it to a shop , cost me 20 $ just for them to break that darn bolt ..well worth it though .. yet that was after i cut the plastic cover off ...i used a razor blade , get a dremmel it will save you alot of time and error , also if you do what i did go on ebay and get replacement covers for the darn thing , or go to ur local junk yard and get some more covers , you dont have to put them on instantly , but its just wise ....
put them on next time your working on the car and have free time ..
ow if you do decide to cut the plastic cover off , which im sure im gonna get burned for telling you that , be smart and cut it so that you can reuse it , only cut it enough to bend the plastic to get the thing off , in fact now that i think about it , i dont think you have to remove the lower cover ,
the water pump is up top , well have fun , and be smart , take the car to a local tire shop and have em break the bolt for you , it might take time and energy such as you and a buddy with a truck to tow the darn thing over , but you will enjoy having them break it for you far more than doing it yourself ... plus if your planning on doing any major work on that motor down the road , a bolt once broken is easy-er to take off than ... well you get the idea ..
edit : while doing so be ultra careful , i screwed up and messed up my timing while being frustrated as hell with the cover ... didnt have a timing gun or tdc gauge or a big enough screwdriver so i had to eventually take it to the shop to have them finish it , instead of a 150$ waterpump job at the shop , it cost me 230 for a timing job ...
