Prestone Command® Heavy Duty 2 in 1 Flush & Degreaser
Introducing Prestone’s NEW Command 2 in 1 Flush & Degreaser, an innovative and easy-to-use cooling system cleaner for heavy-duty diesel cooling systems.
Part 1 is an acid cleaner that dissolves corrosion and scale without damaging metals.
Part 2 is an oil encapsulation system that strips grease and oil from all surfaces and flushes it away. Just one use helps prevent overheating, a major cause of engine failure.
Safe for all:
- Drain cooling system, add 2 in 1 Flush & Degreaser and refill with water. (Systems larger than 15 qts may require 2nd bottle.)
- Bring the engine up to operating temperature and ensure circulation through the entire cooling system for 45-60 minutes. Systems that are especially contaminated can run up to 3 hours.
- Thoroughly flush the cooling system with water.
- Drain the cooling system and install half the cooling system capacity with Prestone Antifreeze/Coolant, top off with water and thoroughly mix by driving.
- Verify the coolant concentration and level and top off as necessary.
Do not reuse container. Keep container closed. Dispose of according to federal, state, or local regulations.
