Dodge Challenger overheating issue with intermittent temperature gauge and trunk popping open, despite replacing thermostats and coolant system components on Dodge Challenger

Some Dodge Challenger owners report experiencing persistent overheating issues despite replacing thermostats and coolant system components, which may be attributed to factors such as a faulty thermostat, low coolant levels, a malfunctioning radiator, or a problematic water pump. Additionally, some owners have encountered blown head gaskets, which can lead to the mixing of engine coolant, engine oil, and combustion gases, exacerbating the overheating problem. Intermittent temperature gauge readings have also been reported, with some owners noting that fluctuations in the gauge may not always indicate actual overheating, highlighting the importance of verifying temperature with additional methods. Furthermore, issues with the trunk popping open intermittently may stem from underlying electrical or mechanical problems, necessitating a thorough inspection. For those facing ongoing overheating despite component replacements, it is recommended to bleed air from the system and use a thermal temp gun to identify abnormalities, and to consult a qualified technician for a comprehensive diagnosis if the issues persist.
