antifreeze and aluminum pump housing

[mopar jack]

What antifreeze should I use with an aluminum pump and housing? I'm building a spare 440 for my 71 road runner and will be mostly stock and cast iron except for the water  pump and housing. Also do you locktite bolts and what happens to torque values on the bolts?

any good quality AF is good with Alum as most engines at least have alum heads now , a sacrificial anode is a great idea as well

Since I have 3 newer mopars that use the HOAT formula antifreeze I'll probably use that in the 440. Any suggestions on locktite. I want to make sure the 4 pump bolts are secured correctly. I have short headed bolts but I don't have the nylock style the factory used.

I just use Locktite brand , , Blue should be fine

Thanks Chryco, I don't have a lot of experience with fastening aluminum. I always used anti-seize on bolt threads.

I have added aluminum radiator to several of my old cars and have found this to be superior.
They sit for extended times and I never see evidence of corrosion in them. With Prestone,  seeing corrosion in cap was almost immediate when sitting.

Will be adding the anode soon just to have more insurance.

I like the anode idea. Where will you install it?

[YellowThumper]

I purchased one and will just replace the radiator drain with it. Not as convenient as petcock but ok.

I did the same thing with my aluminum engine.

I was thinking this spare port on the housing would work.

Yes, that should work. I'm not sure that placing one on the radiator will protect
the engine. Gotta think about this. I have one on my engine, and one on my radiator.
Also, check anode initially every six months, as corrosion build up on anode may make it
hard to remove from its location.
