Problem overview

Some Jeep Compass owners report experiencing persistent overheating issues even after multiple thermostat replacements. These problems may arise from insufficient coolant levels or leaks in the system, which can lead to coolant loss. Additionally, some owners find that contaminated coolant quality or a faulty water pump contributes to their overheating concerns. A faulty head gasket is another critical factor that can cause overheating, and it is advisable to have it checked. Improper installation of thermostats during replacements can also lead to inefficiencies in regulating engine temperature. Some owners consider flushing the cooling system to eliminate air pockets or blockages that impede coolant flow. Furthermore, a clogged radiator may hinder heat dissipation, exacerbating overheating issues. If these measures do not resolve the problem, it is recommended that owners seek a professional mechanic's expertise for a thorough diagnosis.
