1989 Civic crankshaft pulley problem

  • 1989 HONDA CIVIC

I have a 89 Honda Civic, standard hatchback, which is a manual transmission, with 84,000 miles. Recently my car has been starting to run hotter, then normal, then hotter. My car was also taking a long time o warm up yet was blowing cold car when it was warmed up. This fluctuates under normal driving conditions. At first, I thought it was just the thermostat. However, when I noticed I was also low on coolant, and put more in, I saw that it was leaking out by where my water pump is located. Seeing how I must remove the timing belt to get to the water pump, I started to do this. However, I cannot get the nut off that holds the crankshaft pulley on. I have tried everything up to a 500 foot pound impact wrench. I have also tried wedging a screwdriver in the teeth of the flywheel, and trying to take off the nut with a socket and a breaker bar. However, the pressure of the flywheel and the screwdriver creaked the case, and the nut still hasn't budged. I am considering trying to sell the car as is because I cannot make any forward progress it seems. Help will be greatly appricated.

Do you
have the same problem?

I use an impact wrench bud, it should do just fine. I would then go get a crank pulley remover/puller, three jaws are better than two. First you should support the engine with a jack and a piece of wood in between the jack and engine. Then remove the motor mounts leaving the tranny mounts and lower the jack just enough so that you can get to the pulley easily. Use the puller and it should come off just fine. Try that let me know
