Brought the work van for an oil change and the guy starts explaining that my washer fluid was filled with antifreeze ( I assume because of the color) he was in a mild panic. The look of relief when I told him I just filled it with rainx washer fluid was amusing
I have 2 of them. Can't really remember the last time i used them. They are nice if you just want a bench top radio. They came free with kits i would be less than happy if i paid much for them
that is a secondary drain port a pvc pipe plug should fit fine.
* should have red what you we're asking instead of smashing my own answer where it didn't belong. some silicon or duck seal would work fine
if it makes you guys feel any better I got the set a while ago on a different deal. the 3/8 broke the first time i used it. the dial popped off and little parts from the head went flying.
