Problem overview

Some Jaguar S-Type owners report experiencing antifreeze leaks due to issues such as a stripped cam and thermostat housing screw, which can contribute to coolant leaks in the engine. These leaks may be caused by various factors, including a cracked header tank, a faulty water pump, or a malfunctioning thermostat. Symptoms of these leaks can include coolant pooling on top of the engine or under the intake manifold, along with dashboard warnings indicating low coolant levels. Repairing the stripped screw issue typically requires replacing the affected components to ensure a proper seal and prevent further leaks. It is crucial for owners to address coolant leaks promptly to avoid overheating and potential engine damage. Many owners find it beneficial to seek assistance from a qualified mechanic or Jaguar specialist to accurately diagnose and repair these coolant leak issues.
