Coolant Bleeder Screw

Looks like someone was busy playing with the internets.

I'd be concerned with galvanic corrosion with the brass female threads and Ti bleeder screw.

I will monitor it at service intervals and let you know in 10 years if I notice any galvanic corrosion.

Dudes.. If y'all are having electricity in your coolant, you've got problems bigger than corrosion.

But yeah, @Loco38SUP could you let me know how that is after 10 years? Just PM me here. I don't change email addresses very often.

How much coolant should be pouring out when I unscrew the oem screw?

None if your car is cold. Some could spill out if the car is hot and your system is pressurized.

Explains it. I shall try again in the morning.

Considering titanium is very noble (maybe even a ducal lord... ehm sorry ) you shouldn't have any concerns about galvanic corrosion. If any did occur, it wouldn't be the screw... or for that matter the brass bung either... you've got aluminum in your cooling path... that's what would act as the anode.

However, unless you're running salt water with no coolant whatsoever - you've already got corrosion inhibitors involved and a relatively non-conductive fluid. I'm guessing dropping a zinc pellet in your cooling line as a sacrificial anode would be much more destructive.

I'm with @zrk - if it becomes a problem... then you've got much bigger issues than a bit of corrosion at your bleeder screw.

Small vid I did going over and installing the bleed screw

If you need a video to tell you on how to install a coolant screw. You really shouldn’t be working on cars……….
