Car heat up issue , probably blocked radiator

So this means there are other ways cooling systems are designed. :). Like in conventional system it is a series of stuff connected. Like one way closed loop. One In and One Out simple.

Does this mitsubishi has bi directional flow. When thermostat valve is closed coolant will not enter raidator but when valve opens it opens for Radiator and close for bypass channel Rite>

yes - you are right.

the other example is a mehran, no bypass port - it just relies on the principle of "energy transfer" meaning when the thermostat opens up, hot water is ejected into the colder region i.e. the radiator, its replaced with cooler liquid which is being moved by the water pump, thats how it maintains a temperature and that is why the coolant intake pipe from the radiator to the water pump needs to be in tip top shape - otherwise the engine will overheat because cool coolant cannot flow fast enough into the engine.

and the above is why the earliest cars like the ford model series had no water pump at all. they just relied on the thermosiphon principle.

what do you suggest for a liana with 115000 km running - double nali radiator or single nali? all available here are of aluminium with fibre tops ?. bubbles in radiator are cuz of blockage or air inside?

choose either, it wont matter. If you are experiencing bubbles in the radiator cap neck then do an air purge and dont use plain water in it.

ok...so bubbles dont have anything to do with gasket leaks etc? car is not over heating and running fine.
