Hi everyone
It's been a while. Hope you're all doing great.
What would you all recommend applying to the engine coolant drain plugs to avoid the metal plug and aluminum block corroding together with the presence of all that coolant. I was just going to slap on some copper paste and reduce the 15 ft lbs book torque value by 20-30% to account for the paste lubrication - but then I stumbled upon some articles mentioning that aluminum + copper paste + coolant could effectively promote galvanic corrosion.
Now I'm all confused. I want to make sure I get it right so your thoughts would be very much appreciated.
Cheers,
Col
