COOLANT FLUSH

Why is a coolant fluid exchange so important?

Coolant breaks down like any other engine fluid. Just as motor oil has crucial engine performance additives, your coolant has additives that prevent boiling, freezing and corrosion. When these additives are low, contaminants and fragments can begin to build up on your radiator, affecting its performance.

How often should a coolant exchange be performed on my vehicle?

GM recommends a coolant flush every 5 years or 240,000 kms whichever comes first.

What might indicate that my engine’s coolant needs exchanging or inspection?

Significant coolant problem indicators:

·         Low coolant levels: If your coolant is low, you could have a leak in your cooling system. You may be able to see the leak under your vehicle, and you may be able to smell it as well. If you notice this, get your coolant inspected at the soonest opportunity. Other potential leak culprits include a bad radiator cap, blocked radiator or damaged sensor.

·         Discoloured coolant: Coolant color should never change, but it can when coolant gets contaminated with debris or it’s been in your car so long that the additives in it deplete. When coolant color changes or gets cloudy, bring it to us to see if it needs to be changed.

·         Engine overheats: Worst-case scenario: your engine can overheat, seize-up and crack, causing your car to stop completely. If this has happened, it’s probably too late for a fluid exchange — you may need a whole engine exchange.

What is the benefit of having a transmission fluid exchange performed?

An exchange prevents your transmission from slipping due to wear and tear – and it helps prevent your vehicle from not moving at all.

By having your old transmission fluid exchanged with new fluid, you’ll be back to driving with a clean, smooth-shifting and replenished transmission system. You may experience what feels like a night-and-day change, since refreshing your system with friction-modifying additives means gears shift more smoothly.

How does transmission fluid break down, and what happens when it does?

Just like motor oil, transmission fluid experiences breakdown from normal wear and tear.

When a car’s transmission shifts gears, it causes friction. This, in turn, generates heat, and that heat must be carried away by the fluid. The greater the load on the transmission, the more heat it creates and the hotter the fluid becomes. The hotter the fluid runs, the more quickly it experiences breakdown and the shorter its lifespan. When this happens, the fluid’s ability to lubricate crucial parts is decreased.

Adding insult to injury, heat generated from the transmission’s mechanics causes debris from the gears, bearings and friction plates inside the transmission to compromise the quality of the fluid.

Transmission fluid contains additives to produce oxidation stability, reduce foaming and inhibit corrosion; these, too, can get worse over time.

Changing the fluid at regular intervals is the only way to get rid of the contaminants, boost the benefits of additives and keep your vehicle running smoothly. Properly maintained transmission fluid cools and lubricates the moving parts, enabling hydraulics and gears to transfer power from your engine to your wheels. Now, that’s an important job.

Never wait for symptoms of transmission fluid breakdown to progress.

What symptoms may indicate my transmission fluid is breaking down?

Few signs indicate there’s a problem with your transmission fluid – until it’s too late.

Automatic transmission: A usually smooth ride may feel sluggish when shifting gears or the time it takes to shift gears may take longer. This is usually a sign that your transmission fluid is no longer coating your transmission parts.

Manual transmission: “Clunking,” “clashing” or waiting for your transmission to “catch” are definite red flags. Unfortunately, by then, damage has likely occurred.

If any of these symptoms occur, do not ignore them. Have us inspect your vehicle as soon as possible in order to reduce damage to your vehicle.

What are the other ways to tell your transmission fluid is old?

Your transmission dipstick can also tell the story about your transmission fluid condition.

·         The colour: Automatic transmission fluid should be translucent and/or red in color. Meanwhile, healthy manual transmission fluid may appear red, dark green, blackened or even translucent. If your transmission fluid looks cloudy, or has a dark or brownish tinge, it might be time for a fluid exchange.

·         Burning odour: If your transmission fluid has a burned smell, it’s time for new transmission fluid.

·          Low fluid levels: Though it may help to do a transmission fluid exchange if your transmission fluid dips below a safe level, it’s really time for a transmission inspection since you shouldn’t be losing fluid.
