Doubt age has anything to do with it!I did the same thing, Chart, lol! Must be the age factor?!
Went to Pick A Part today and got some things. Hot sunny day, but they moved the cars around and I had to walk and walk to find what I needed. Got home just before the thunderstorm. Now, looked in my tool box and my quarter inch drive set was missing. After rain ended, back to the yard and they did not have it at the desk, 2 others but not mine. Out to the back end in mud and there it was, in the mud. Got home and washed the sockets off and the box. Drying now.Some days I feel stupid.:angry:
But it can be a learning experience.
PS pump from DOHC.
I took it off with a 10mm open/box wrench.
When off, I noticed the holes in the pulley.
Hope this helps someone else sometime.
