Squirted some grease into the zerks, probably the first time that's been done in 25 years!
Surprised by how few zerks there were, but it was still enough to take most of the 'small' marine grease tubes.
Changed out the oil with some Rotella 15W and replaced the filter. She was a bit overdue
with almost 6k since the last oil change! Thankfully she's still relatively low miles and there doesn't appear to be any resulting problems, but I should've done it when I first got her. Much MUCH quieter now, though, to be sure.
Finally got the belt pulley tension right so that there's only minimal squealing of the driver's side alt belt after a start.
Got the wires and additional engine bay terminals to convert the inside cab bus bars over from 24V to 12V, figure it's easier and cleaner to do it that way than to run new wires and to ignore a bus bar I'll never use.
Spent maybe an hour trying to identify where the coolant leak is coming from; I think it's the radiator itself, and will need to be pulled and patched. Bother! How did that happen?! These old trucks sure do need a lot of loving... I'll have to wait for much warmer weather, I suppose.
Found out where my parasitic power drain was coming from, just need to figure out how to isolate it and fix it without cutting a bunch of wires and making a big mess...
