Suzuki-Alto-Alto Idle Speed and Temperature Problems

Your car is as old as my antique Alto in 2003.

1. After cleaning the throttle, the idle speed is high. (Especially with carburetor cleaner) If the accelerator needs to be reset or run for a period of time, you can idle for 10 minute.

And whether the idle speed before oil washing is around 900.

Is the intake manifold leaking? If it leaks, the idle speed must be high. Check the pcv valve to see if it is broken.

2. Has the water temperature reached the red line? The fan will fall off as soon as it is turned on. Is antifreeze ineffective? What is its boiling point?

Take a closer look at the hot air part, and the leakage can be repaired.
