1993 Toyota Camry mileage: 135,000. My radiator was corroded and leaking. A new radiator has been fitted. I have now been told that the head gasket needs to be replaced because there is a major oil leak. This did not exist when I took it into the garage. Is this something that can happen when a new radiator has been fitted? I am now expected to pay a much higher repair bill. Is it likely that the garage could be negligent?
Replacing the radiator would not cause the head gasket to fail. What probably occurred is the head gasket was close to or failing before the radiator was replaced? The old leaking radiator probably caused the engine to over heat.
