Penray says its Pencool 3500 Small Engine Cooling System Treatment with Stabil-Aid is the first coolant maintenance additive designed exclusively for smaller engines such as refrigerator units, diesel pickups, small delivery vans and generators.

Pencool 3500 is designed to help prevent liner and block pitting, eliminate plugging of cooling system passages, inhibit insulating mineral scale deposit, prevent premature water pump failure, extend antifreeze life, stabilize antifreeze and overdosed additives, and protect all six metals commonly found in cooling systems.

Pencool 3500 also contains ethylene glycol so it doesn’t alter the freeze point, according to the company. For more information, go to www.penray.com.
