Yes, the water pump can fail without causing the head gasket to fail on a 1998 Infiniti Q30. A failed water pump may lead to overheating, but if the engine is monitored and turned off in time, it might prevent head gasket damage. However, prolonged neglect of a failing water pump can result in serious engine issues, including head gasket failure. Regular maintenance can help mitigate these risks.
