Ok so I have a civic 91 hb with a 1st gent b16 swap. I believe that the water pump is leaking because there is water dripping between the timing belt plastic cover and the block.

I though of 2 choices since I dont have a compressor/ impact gun.

1st choice: I will ask a friend to remove the crank pulley using his impact gun, so I can remove the lower timing belt cover in his home and after that, he will tight the pulley back. Then I will go home and replace the water pump... After the replacement, I will go and visit him again so I can install the lower plastic cover again.

2nd choice. Make him loose the crank pulley bolt and then tight it a little bit. I will drive home slowly so the bolt doesnt tight and remove it with a breaker bar (i guess it will be easy to remove).

 

I've never had any luck with an impact wrench, so I suggest 3) put a very long pipe over your breaker bar and break it loose that way. I had a terrible time with mine, tried impact wrench, penetrating oil, torch, ext, and finally got it off with little trouble using a 2.5" diameter 4' long pipe of PVC plastic of all things, over my normal ratchet. It was my last resort because I thought the plastic would crack.

but of your options, 1 sounds better. They seem to seize up again just from tightening without even running, and what if it happened to work loose on the way?

 

Dont drive it with the crank pulley loose under any circumstances! I really recommend buying a crank tool or a chain wrench and just doing it all at one time.

 

use the breaker bar and a long pipe...it's WAY more effective than any impact gun i've ever used. just make sure you can keep the flywheel from moving

 

I did option #2 when I had to replace my water pump. The only other problem I had was working the pulley off.

 

I use an elec impact to do mine but if by hand try this

with an impact gun it will go out so easy......

 

well we tried today with the impact gun and it didnt work!

Then we had to remove the starter, lock the flywheel with a prybar and then we used a breaker bar and a long *** pipe and it came off easy....
