Pencool 2000 anywhere

[Author nameAuthor names are only available to PAS members.]

After the discussions a few years back that pencool 2000 is the bestus stuff to add to water only radiators I cannot find it anywhere. Any sources or equivalent substitutes out there?

Jim,

I contacted PerRay that used to make Pencool and they no longer make it. Right now I am using No-Rosion. NAPA also has a Water Pump Lubricant / Anti Rust available. I haven’t heard good or bad about either. NoRosion specifically gives a dosage for straight water. https://www.norosion.com/norosioncoolant.htm

LubeGard has a diesel truck anti-corrosive additive, but does not mention use with water only. More research is required.

Thanks Dave for tracking pencool status down and Robert’s NAPA Kool suggestion.

Jim,

One other thing you might consider to prevent cooling system corrosion is running with a zinc or magnesium anode in the cooling system. Many people hang them in the radiator neck. There are some made that will thread into the block or radiator drain hole. Magnesium works best in fresh water, but Zinc will also work.
