Aluminum Z Head Saver

[drpepper1885]

I recently acquired a 1915 roadster with an aluminum Z head. I was told that these type of heads tend to deteriorate if you do not use a "head saver". I got the pictured head saver part from one of the parts vendors. Can this part be installed in the water outlet as pictured below? Thanks for your feedback.

Yes, you can do that, but be sure to add a little silicone around the wire, you can't squeeze the rad tube enough to eliminate a leak if installed this way. I just hang mine on the overflow tube in the neck of the rad, in a couple of years they're gone and I hang another.

Good point about being able to tighten the hose. I like the idea of just attaching to the overflow tube in the top of the radiator. That would make it a lot easier to monitor when to replace. Thanks for the advice.
