Coolant
Hi all. I am going to drain my coolant [water] in my '28 for the winter. If I drain via the petcock on the lower hose steel tube will I safely drain all with no chance of leaving residual water to freeze? Thanks, Frank.

Re: Coolant
It'll drain the system just fine, just poke a straw/wire or something into the petcock hole after it stops draining to make sure it isn't plugged. I run antifreeze in mine so number one it keeps the corrosion down and number two, don't have to drain it in the fall.

Re: Coolant
Thanks Eagle. My system is a bit leaky so I have been running water and WP lube.

Re: Coolant
I've never tried it but Water Glass (Sodium Silicate) is supposed to seal up the system without causing reduced efficiency or plugging of already compromised 80+ year old system. Mine is nice and clean yet and cools great on 50/50 mix.

Re: Coolant
I get it from Napa. The parts guy at our local store is an old car guru and he told me which brand/type to use. Didn't even look at what kind it is as I've known him my whole life and trust he knows what he's talking about. So basically, I have no idea!

Re: Coolant
Previously on the Barn Thought I read to stay away from Antifreeze with silicates, stay with the Green antifreeze.
Is the additive above safe, it has Silicate? |

Store/fill with 50/50 green antifreeze, drain and save it in the spring for multiple winter storages. Helps keep rust/corrosion from happening during the winter due to condensation and no worries about freezing. Make sure to use the green antifreeze. |
