Spider mites (Class Arachnida) are tiny sap-sucking plant pests. They attack the underside of leaves and suck the vigor from the plant; with large infestations they may even kill a plant. As soon as you spot an infestation, it's time to take charge and get rid of them!
Back in the day, no matter which brand you chose, antifreeze was green. The glycol-based formula contained silicates as corrosion inhibitors. You mixed the antifreeze 50/50 with water and poured it in the radiator. As the engine operated, the antifreeze performed its primary duties of carrying heat to the radiator, preventing freezing (hence the name) and protecting against corrosion in the cooling system.
Engine Coolant. Coolant Leaks and Coolant Types. It is very important that antifreeze or engine coolant is changed every two years (four years for vehicles with long life coolant) to replenish the additives that protect the cooling system from rust, corrosion, pitting, electrolysis, gelling and foaming.our automobile cooling system should have a concentration of 50% to 70% antifreeze to water at all times. Vehicles using Extended Life antifreezes should be changed in about 50,000 miles or 4 years to prevent system damage and radiators and heater cores from plugging up.
