HONDA CR-V — What to know
The CR-V is one of America's best-selling SUVs and has excellent long-term reliability. The 1.5T turbocharged four-cylinder (2017–2021) was subject to a documented oil dilution issue in cold weather — Honda extended the warranty on affected vehicles.
What is this repair?
Plain-English overview
Coolant hoses, pipes and the expansion tank carry hot coolant between the engine, radiator and heater; a split hose or cracked tank causes rapid coolant loss and overheating. The cooling fan ensures airflow at low speed.
