What Happens During a Coolant Change?

As coolant has an important role to play in controlling heat from the engine, having your coolant changed at regular intervals is essential.

When your engine coolant needs replacing, a professional mechanic will:

1. Drain the old coolant once the engine is cold

2. Refill with the right coolant at the correct strength

3. Run the engine up to temperature

4. Check the coolant level and top up if needed

5. Dispose of the old coolant safely

If your old coolant is badly contaminated, the garage may also recommend flushing the system before refilling it.

How Often Should You Change Your Coolant?

Depending on the vehicle, your engine coolant will likely need changing every two to three years or around 30,000 to 50,000 miles.

Many newer cars use long-life coolant that can last around five years, so check your owner's manual for the right interval and coolant type for your car.

Signs Your Car Needs a Coolant Change

You should book a coolant change at the appropriate intervals, so if it's been a while since you booked one, now's the time.

Otherwise, your car may need a coolant change if the coolant is discoloured, rusty or sludgy.

What Affects the Cost of a Coolant Change?

The cost of your car's coolant change can vary depending on:

• The make and model

• The coolant your manufacturer specifies

• Whether your vehicle needs a drain and refill or a full flush

If the garage identifies any other issues that need fixing, this may also influence the price.

Keep Your Engine Running at the Right Temperature

Booking your coolant change on time means your engine stays protected without waiting for a problem to remind you.
