Consumer Description

It has been observed that the antifreeze and oil are intermixing in the antifreeze reservoir, causing the check engine light to illuminate and the system to register a code of PC304. This particular code is indicative of a cylinder misfire, which can cause the car to stop functioning properly and eventually lead to potential engine damage. To resolve this issue, it is imperative to replace the oil cooler filter adapter and flush the engine. This will ensure that the antifreeze and oil are no longer mixing and the engine is functioning efficiently. Therefore, it is highly recommended to take immediate action and get the necessary repairs done to avoid any further damage to the engine.
