The take away from the video:
Have you tried the Honda Type II coolant in your Passat yet? Wondering how it is working out for you since from your description it sounds like very good stuff for an aluminum engine.with all this heater core stuff, im not sold on G13 even though I just purchased 2 more gallons with my gift card
Best long life coolant for aluminum engines I have found is Honda's Type II teal color- it seems to stay "like new" forever, I threw new rings in my 1988 CR250R this summer with decade old Honda coolant in it and it was still perfect with zero electrolysis in the rad or passageways. Not sure how it would hold up to a diesel but im half temped to try it out
Sorry about your luck, it has been a few months, how did you make out? Thanks for starting this thread!
I just has a small coolant hose start spewing and topped up with approx 750ml of distilled water. I need to add some more coolant and my local Napa almost sold me some Zerex G05 but my spidey senses started tingling and I politely refused. After reading this thread I am glad I did not buy it. One thing that would have had me facepalming later is that Zerex comes pre mixed, but I need concentrate in order to get my mix closer to 50/50 considering three blown hoses in the past two years and I vaugely remember dumping the last of my Pentosin in last time and not being sure if it was "enough".
I think I am going to have to actually go into my VW dealer and ask for some G13.
here's a link with a good description of Pentosin's coolants.The Pentosin G13 coolant is available thru NAPA , Your local store may have to order it in from warehouse. I work at a napa store, and ordered it in for my car, but it has been selling well. to others who have VW cars and garages,
