Use sealant on new water pump?
I’m preparing to change my water pump. In the past - when working on 80’s/90’s cars, I always clean the mating surfaces then apply a thin coat of Permatex RightStuff to both mating surfaces and both sides of the gasket. Is this still a good practice? Will it hurt anything?

The service manual specifically states:
- do NOT use sealing compounds as they can dislodge and ruin your engine.
- Just use a NEW, proper gasket.

I have a 2013 6.0l. I always used a very thin coating of liquid gasket (Permatex RightStuff) on water pump mating surfaces and gaskets in the past but these were much older cars (80’s). I never used enough that any of it could dislodge as it was only a thin coat. If I’m not supposed to use it I won’t, I was just double checking.

2005 service manual.
Procedures evolve as we find better ways of doing things. Do you still change your oil every 3,000 mi?
Differential covers now use reusable rubber gaskets instead of silicone, which I'm thrilled about, because removing the old stuff was such a pain in the dick and it always seeped anyway.

No they aren't. Manufacturing techniques have improved to allow tighter tolerances and greater efficiencies. Older cars required much more maintenance, so good riddance.
We learn from past mistakes, and it can take time to find sources of problems we used to have. So maybe bits of silicone floating around your engine was harming your old car, but you just didn't realize it until now.
