Check if the radiator fan circuit is working properly (going on and off at specificed temprature). Also check if the coolant container is showing a mixing of oil (the coolant container will contain some oil if there is any gazget seal crack in the cylinder head block due to overheating). You can check this by opening the coolant container cap and there will be some amount of manoiase type sticky material near the neck of the cap.

Hello Vijoy.
I own a Matiz too. I had faced similar problems earlier...

As advised by other readers, get the thermostat, cooling fan, coolant level, hoze pipe leaks checked thoroughly.

& if still the problems persists, then get the spring loaded valve removed (which is in the path of coolant flow). It is placed somewhere around the distributor, just around the place where a hoze pipe from engine block towards the radiator.

As the car ages, the spring valve doesn't activate effectively.. thus limitimg the coolant circulation.
Which results in overheating every 30kms of running.

Need to check the engine packing. If there is a leak in engine packing, the coolant will get dried and the coolant keep reducing from the can. So take a check..

Expert`s comment:

There could be malfunctioning of temperature switch. Replace the temperature swith and check, if still there is excessive temperature then thermostat switch needs to be checked and replaced.

Try all the needfull as suggested by the Experts & Owners, If did all the needful as suggest, but still facing the same problem, replase the radiater, sometimes formation of Iron inside the radiater, cause the same problem.
