Fitment Details
When replacing coolant hoses, it is advisable to replace the associated hose clamps to ensure a leak-free seal. Ensure the hose is routed without kinks to maintain optimal coolant flow; if the hose appears brittle or exhibits signs of surface cracking due to heat, replacement is recommended to avoid coolant loss and engine overheating.
