Do I need to flush my cooling system?
Son added 1/2 gallon green antifreeze. Specs orange. See only green in reservoir and radiator. Shouldn't it appear off color if it actually had orange in it?
Drain the cooling system, then refill with the correct 50/50 mixture of anti-freeze and water. No need to flush the system.
