When do I need a Coolant Flush?

CoolantAt Tierra del Sol we are often asked. “when do I need a coolant flush”? The simple answer is that any time is at least a good time to consider a coolant flush.

How Do I Know When I need a Coolant Flush?

During the summer months, we rarely think about the coolant in our automobile unless we encounter some sort of problem. Perhaps the temperatures have started to cool and we are starting to need a little heat inside of our vehicle. When you realize that the heater is not blowing as hot as it did in years past or in some cases, you may not have any heat blowing at all – it’s time to consider a coolant flush service.

No heat is an indication there might be a problem in your cooling system. During summer months, we do not open the heater control valve, which is simply an on/off mechanical valve that allows coolant flow through the heater core inside the dash panel of your car. However, coolant still flows through the remaining parts of the coolant system. Due to the fact that coolant no longer flows through the heater hoses, loose dirt and corrosion from within the system tend to migrate to those areas of low flow or activity. Think of it as being similar to a sink drain. Eventually, any contaminants create a partial blockage, total block of that water passage. The result is “no heat” because the coolant isn’t able to move freely through the heater core.

Another important consideration is that coolant, over time, loses its chemical additives and weakens in strength. Many of the chemicals in the coolant are present to help keep the boiling point of the coolant at a strength that provides optimum engine cooling. As leaks develop, a common practice is to “top-off” our coolant level using tap water which in itself, has minerals that actually lead to the deterioration of vital engine components. Adding tap water also dilutes the original formulation and increases development of corrosive acids that eat away at metal parts of the system. Also, over time and under daily usage the corrosion inhibitors within the coolant are depleted.

How to Keep Your Vehicle in Tip-top Cooling Shape

Engine components such as water pumps, radiators, heater cores, water control valves, etc…. are very expensive to replace. A regularly scheduled coolant flush helps keep those components from premature corrosive wear and tear. This ensures you’ll remain warm during cold winter months and the engine will remain cool during the hot summer months.

A Tierra del Sol Automotive cooling system flush provides you with the peace of mind in knowing your vehicle’s cooling system is being maintained at the highest level of performance. Our automotive technicians will use a “BG Products” cooling system chemical package that is included in the price of your vehicle cooling system service.

Before your cooling system is flushed, our technicians add a system cleaning chemical. Next, the vehicle is brought up to operating temperature and allowed to run to give the chemical time to clean the system thoroughly. This cleaner suspends all contaminants in the fluid.

Then, technicians transfuse the system, using pressure, to force the old and dirty fluid from the system and replace the old coolant with new coolant.

Finally, additional chemicals are added to the system.

Have you ever noticed those tiny annoying leaks that leave a drop or two of coolant on your garage floor monthly? Unfortunately, it is not uncommon for coolant hoses to weep at a clamp around the radiator or thermostat area. 

  • A “SYSTEM SEALER” to aid in the prevention of leaks.

This “SYSTEM SEALER” additive helps to keep the coolant at bay, within the system, and not on your floor.

  • A “SUPER-COOL” additive that prolongs the corrosion inhibitors in the system and keeping operating temperatures at a lower temperature.

Tierra del Sol Recommends…

The best way to keep a healthy cooling system is to replace your coolant at regularly scheduled maintenance intervals. Many coolant manufacturers boast their coolant as lasting “150,000 miles”. This may be true, mileage wise, however, Tierra del Sol recommends that the depleted corrosion inhibitors be replenished more frequently – every 30,000 to 60,000 miles.

Stop by Tierra del Sol Automotive or contact one of our friendly Service Advisors and inquire about our cooling system service. Your automobile will “Thank You” for it!
