Common reasons for this to happen:
- Perforated radiator tank or core: This is fairly easy to spot as there will be signs of leakage around the radiator.
- Bad radiator hoses: The hoses connecting the radiator to the engine can also deteriorate and produce leaks from as little as a pinprick puncture to a full-on burst wall. Hoses usually become brittle and weak as they get old, making them prone to failure. Hoses will need to be replaced if they are found defective.
- Bad water pump: Coolant can also escape from the water-pump housing. Usually, the pump seals fail following the bearing failing. This happens mostly when the pump is operating, so the mechanic will check for this with the engine running. If this is the source of the leak, the pump will need to be replaced.
- Faulty radiator cap: It is also possible for the radiator cap to lose its ability to maintain system pressure. This will allow the coolant to reach its boiling point at a lower temperature than intended, and possibly allow steam to escape, which introduces moisture to the system.
What to expect:
A top-rated mobile mechanic will come to your home or office to determine the source and cause of the coolant leak, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
How it’s done:
The mechanic will come to your home or office to diagnose the leak and inspect the entire cooling system. The mechanic will pressure test the system if needed.
How important is this service?
When engines overheat due to a cooling system failure, it is possible for damage to be sustained by mechanical parts. For example, cylinder heads may warp, resulting in a loss of cylinder compression and allowing coolant and oil to commingle. This can result in catastrophic engine damage.
If you see abnormal temperature gauge readings or notice fluids on the ground under the engine compartment of your car, have the vehicle checked as soon as possible. You can save a lot of money by catching problems early that relate to the cooling system.
