Clean frequently
The car radiator's coolant flows constantly, bringing in a lot of dirt and debris that might block the system. Thus, for optimal operation, the radiator needs to be cleaned and maintained on a regular basis. The radiator should be cleaned and repaired every other year.
Prevent acid corrosion
Corrosives are present in the coolant that is frequently utilized in engine cooling systems. Long-term usage of these corrosives will lead to the radiator rusting and corroding. As a result, it's imperative to keep the radiator out of an acidic environment for as long as possible. It is advised to often replace the coolant.
Shield the radiator from collisions
Installed near the front of the vehicle, the radiator is susceptible to damage from stones, dust, and other road debris. Thus, when driving on the road, you should try to avoid running into road barriers, ditches, etc.
