Leave thermostate idher tu log Auto fan nahi karta they say direct kardo for better engine cooling
Ese leya Corolla original thermo is for around 200 Rs only. Bcoz no demand.
Well interms of Desi mechanic i have been getting my car repaired from YEARS but i have seen only one mechanic ( who is like other is not educated) that is my mechanic who says without thermostate ur car engine life will decrease.
He is young and some time says i wish main parha likha hota tu manuals parh kar gari theekh karta...
