Guys I recently bought a swift- 16, and I think there is no thermostat in it because,
1) The heater is not blowing hot air. both heater pipes are always on normal temp on touching.
2) On the highway, the temp needle stays around 1/3. In summer it was always in the center but as winter is coming and I belong to northern areas, now temps stays lower (1/3, ) because water is always circulating.
In city drive, however, it is always in middle and the fan turns on around 95 degrees (tested with obd). The fan is not direct and is on auto.
Maybe it has the thermostat and its just stuck open.
Now I visited Suzuki i9 3s and they quoted 5k labor for just installing the thermostat plus 5300 is the price of the OEM Thermostat.
I flushed the cooling system when I bought the car and switched to zic coolant (water was being used before).
The cooling system seems to be working up to the mark as I have taken the car everywhere, lots of highway travel around 130 km/h.
The radiator fan seems replaced but works flawlessly.
My guess is, as the thermostat is removed, means the car might have had severe heating issues in the past.
Now question is
Should I pay for that 5k labor for the thermostat installing and also get the cooling system thoroughly inspected by the dealership. My guess is the total expense will be around 20k keeping in mind if something else needs changing.
Or get the thermostat installed from outside (my mechanic will do it in maybe in 500 labor) and keep a close eye on temp for a couple of days using obd. I have bought the thermostat from 3s.
