“Why Does My Tiggo 8 Pro Feel Like It’s Cooking Itself in Karachi Heat?” Detail:

Some Tiggo 8 Pro owners complain that on hot days o r long traffic jams the engine temperature gauge spikes fast — as if the car is overheating. Could a stuck thermostat i.e. thermostat not opening properly be behind the overheating? o r is it more likely due to poor coolant quality, radiator fan issues, o r clogged radiator hoses in our dusty Pakistani conditions?

Overheating in the Tiggo 8 Pro during extreme heat o r long traffic jams can definitely be related to thermostat problems — but it’s not always the thermostat alone.

Most likely reasons:

Thermostat stuck closed:
The thermostat fails to open fully, restricting coolant flow. This makes the temperature rise quickly, especially in hot Pakistani climates.

Low-grade o r incorrect coolant:
Many workshops use cheap coolant that evaporates o r breaks down quickly. This lowers cooling efficiency.

Dust-clogged radiator fins:
Pakistan’s dusty environment reduces airflow and cooling performance.

Radiator fan lag o r low-speed failure:
If the fan isn’t switching to high speed, heat spikes occur in traffic.

How to fix:

Test thermostat opening temperature

Flush coolant + use original Chery/Long-life coolant

Pressure-wash radiator fins

Check radiator fan relay and high-speed mode

If the overheating is sudden and severe, a stuck thermostat is the top suspect.
