You won't need the alignment tool unless you remove the oil cooler housing.

Got it! I got the pressure sender off with your advice. 8 inch adjustable wrench worked perfectly.

I'm gonna put everything back together, new coolant, oil and filter. Fix the wiring and I'll let you know how it goes after.

Btw for the connection to the pressure sender, the wiring is a little different. Right now one of the wires has a spade on it and both holes are the same diameter. On the new unit, there's spades for both connectors and one of the holes is bigger.
