What is this repair?
Plain-English overview
Coolant service — including replacement, system bleeding, pressure testing or sensor repair — maintains optimal engine temperature and prevents corrosion inside the cooling circuit. Modern long-life coolant should still be replaced every 3–5 years as inhibitors deplete.
