Replace Your Coolant On A Regular Basis.

Replacing coolant on a regular basis will prolong the life of the radiator and other cooling system components. Most new car maintenance schedules call for coolant changes every three years or 50,000 miles. At Modern Auto Air we consider that too long and recommend every two years or 24,000 miles.

Some additives provide "reserve alkalinity" to neutralize internal corrosion before it can start. As long as the coolant is changed before its reserve alkalinity is depleted, the cooling system should be no worse for the wear. If you wait too long, the result can be expensive internal corrosion in the radiator, heater core and engine.

How can you tell when it is time to change the coolant? The only way to know if the coolant still has adequate corrosion protection is to test it. By dipping a test strip in the coolant and noting its color change, you can determine coolant condition and whether or not it is time to replace it. See a Modern Auto Air technician and allow us to check your system.

When coolant is changed, the system should be reverse flushed rather than simply drained. This helps dislodge and remove accumulated debris and debris in the system. It also removes old coolant that would otherwise remain in the engine block.

Cooling system should be refilled with a 50/50 mixture of ethylene glycol antifreeze and clean water. This provides freezing protection down to -34 degrees F and boil-over protection to 265 degrees F.

When we replace the coolant is changed, we always inspect belts and hoses. and make a visual inspection for leaks. Also we pressure test radiator and cap and check operation of heater and defroster. See a Modern Auto Air technician and allow us to check your system.
