Automobile manufacturers require scheduled engine coolant

changes in order to maintain warranty coverage. Following

the warranty period, engine coolant changes are still

recommended on a specific schedule to maintain optimum

condition of the cooling system.

Engine blocks, heater cores, hoses and water pumps are not

typically drained during a traditional cooling system fluid drain

and fill. In fact, up to 60% of the used contaminated fluid can

remain in the system.

Just like motor oil and transmission fluid, engine coolant

deteriorates over time, forming damaging scale, deposits, and

acidic by-products.

Contaminants are difficult to remove when much of the old

fluid remains in the cooling system. Much of this damaging

debris stays in the cooling system, slowly deteriorating

internal components.

Some vehicles are now being factory filled with extended life

coolants. DEX-COOL™ from General Motors, with its

distinctive orange color, is the most prominent example. If

conventional coolant is mixed with extended life coolant, the

extended life benefits are eliminated, as is the extended life

warranty. As such, it is very important that extended life and

conventional coolants are segregated and no cross

contamination occurs.Cooling System Flush and Fill

Machines make the chore of engine coolant changes much

easier by connecting to the cooling system through the upper

radiator hose. Each machine removes most of the old

contaminated fluid from the entire cooling system, including

the engine block, heater core, water pump and hoses. The

cooling system is then simultaneously filled with new or

recycled pre-mixed engine coolant. Radiator Flush chemicals transform the old fluid into

a safe cleaner to remove sludge and deposits that could

cause contamination of the new engine coolant.Flush Machines make the removal of

suspended sludge, deposits and wear metals possible,

providing unparalleled maintenance and protection.

Deposits that can cause poor heat transfer and restrict fluid

flow are safely removed from the cooling system and hoses

by using  flush chemicals, in conjunction

with flush machines.

Adding  radiator sealant seals small pin-holes and

cracks to help prevent fluid leaks that are common following

traditional engine coolant changes.
