The vehicle in question is 2000 Honda CR-V. Seems to have some nasty blue/green coolant in it. Unknown service history before 201k, when I got it. Has 225k+ now and I changed all fluids except for clutch fluid and coolant.
I happen to have ~10 liters of Full Strength Pentosin Pentofrost E coolant from previous vehicles. Don't want it to go to waste, and tried to sell it locally, but no buyers yet. So, with my vehicle being waaay out of warranty, are there any strong red flags about using this Pentofrost E in the 2000 Honda CR-V? Will use distilled water for 50/50 mix. Description leads me to believe that I should be ok, considering most of Audi/VW/Lamborghini/Bentley vehicles have aluminum heads/blocks, just like my little Honda... But if it is somehow known to affect head gaskets negatively, or anything else, then I wish to know. Planning to do a full coolant replacement when I tackle the timing belt and water pump.
Here is the description from included PDF:
Pentofrost E is an environmentally friendly Antifreeze CONCENTRATE for multipurpose applications in water-cooled engines. This coolant provides the same exceptional performance as our Pentofrost ++ but it is utilizing a more environmentally friendly manufacturing process — now using glycerin in addition to our glycol base. It does not contain any nitrites, amines, or phosphorous containing additives. Pentofrost E protects all material used in cooling systems and is recommended for non-ferrous metals and year-round use. Pentofrost E can be used where the VW G11, G12, G12+, G12++, G13, and MB G40 are required. Meets ASTM D-3306.
