FAQ

How long does a coolant service take?

About an hour of work on a straightforward car, longer on engines that need a vacuum fill or a slow bleed with the heater running. The bleeding is the part that cannot be rushed, so a shop that books it as a quick job between two others may cut that short.

Am I being sold this too early?

Possibly. A flush is a standard add-on at the counter, and the honest test is what your manual says and what the coolant measures. Ask to see the test strip or the refractometer reading. If the answer is that it looks dirty, that is an opinion about dye.

What should I check in the days after?

Look at the reservoir level when the engine is stone cold, not hot, and expect it to settle a little as the last air works out. The heater should blow properly hot and the gauge should sit steady. Ask whether the pressure cap was replaced, since an old cap undoes a good job.
