✅ Yes — stuck-open thermostats reduce efficiency.

Symptoms:

Weak cabin heating

Engine running below optimal temperature ~70°C o r less

Regions affected: Murree, Swat, Gilgit, Abbottabad during winters

📉 Conclusion: The thermostat may be stuck open o r soft-calibrated, reducing heating and fuel efficiency.
