Anaerobic sealants

[Waterloo]

It's funs stuff, especially when you start getting into all of the bits and pieces... There is always something that needs attention or replacing. Do it all now while it is apart, because once it is back together, you are not going to want to tear into if for awhile.

The front structure, radiator mounts, in fact all of the mounts, replace them all. If you have any power steering cooling lines like mine, they were rotted out, up under the bumper in front of the radiator, never would have known that tubing was that rotted until it had failed on me. It was rotted out at the mounts, backside, which you could only see when everything was apart.

Pulleys too, the main tensioner pulley up near the AC Compressor, best to just replace it now, this one,

FleetPride stocks them, around $30 the last time I replaced mine, they are a regular wear item, around every two years. My buddy just lost his on a new old truck he just purchased. I need to get another as it is getting near failure time, hearing that familiar chirp. And there is no difference in the Gates or Cummins, both use the same bearing, numbers and stampings match perfectly. Cummins wants around $100 for theirs.

Fan clutch too...

Redo the grounds too, and if any of the other cabling looks jenkie or green, replace it now while it is all hanging around. One thing I wish I had done when I was in framing mine, was to strip out the cabling from the alternator back to the starter and battery box. If I could go back in time, I would have pulled all of that cable and replaced with new. One thing I did recently was to install a 300 amp alternator, I tell you what, that was the best $1100 I have spent on this truck. I had little electrical blips now and then, nothing major, just little warnings on the International side. All of that is now gone. I also discovered my cable from the alternator was starting to go green on me. I did not have the time to replace, so I ran a second cable back to the battery, piggybacking that old cable. My Spring project, replacing that cable with a new one, and I will leave the two 0 ga cables in there. Made a huge difference to the electrical system. Of course the wiring in the cab is 19 years old, so that extra juice I am sure is helping get through that old wiring. Resistance stuff...

Good time to inspect everything at the firewall too... Especially with the head off.

The turbo oil return line, I would replace it, mine was pretty rough once I really got to inspect it.

Boy, I am good at spending your money, LOL!
