How often should a coolant pipe be replaced?
11-12,2025
Aging or damage of coolant pipes often occurs after use for 5-8 years or 80,000 to 10,0000 kilometers of mileage. Due to long-term exposure to high temperature and high pressure, their material gradually age. The following methods can be used to determine whether a coolant pipe needs to be replaced.
How to determine if a coolant pipe needs to be replaced?
Check the surface of the coolant pipe for any signs of cracking, hardening, expansion, discoloration, peeling, or obvious wear.
If there are oil stains or sticky or black spots on the surface of the coolant pipe, its internal material may have aged or degraded.
Check for signs of leakage, loose clamp, or cracking or aging of sealing ring at the joint.
Check if the pipe wall exhibits significant thinning, twisting, expansion or bulging.
If the vehicle experiences an inexplicable decrease in coolant or abnormal engine temperature, the cooling pipe should be inspected for any sign of leakage.
