Default coolant system tricks

Yes, I will, last one is a great idea, informative website. I cant recall any coolant leaks there but a few drops at a `T` somewhere near/under VacuumPump long ago, caused by a rusty clamp down there...

I use Zerex G-05 only. If I had to add fluid for some rare reason, I used distilled water only, not mineral or purified etc junks. I`ll want coolant replaced soon (i wish i had more time), radiator flushed and one more thing that`s important. As far as I remember, PO told me that rear hose behind block hasn`t been replaced when engine was out so I`ll have a posting about that when time comes...

I`ll check all ground points, thanks, although that has been done pretty well when my ignition switch became an angry b.tch, so I got stranded in a hotel bsmt in Daytona Beach, FL Not bad...and I had to analyze lots of things to see electric issues , if any. A full disassembly of ign switch later solved the problem. WD40 & dashboard shine was found inside it. (yes, me)
So grounds are ok but will check again. Removed&Cleaned them that time...

Most of the time my alternator is pushing out 14-15V , I mean, that`s what I always see on instrument cluster gauge. Needle Might be at too high. Why?* idk. I like the idea of that coolant sponge that absorbs the extra. *Battery might be shit? Car starts always for the very first crank, even in -20celsius. I`ll check battery too.
