1992 Other Toyota Repair V4 Two Wheel Drive Manual 170K miles

Hi,
im having problems with a toyota starlet, 1992, 170k, 1 litre.

The inlet hose to the water pump burst. I've replaced this hose but the engine is still overheating.

The car has a belt driven centrifugal pump. I disconnected the inlet (top) hose to the radiator and turned over the engine to see if the water pump was actually pumping. No water was pumped out of the hose.

I've no reason to believe there is a problem with the water pump but I suspect that there isnt water getting to the pump in the first place.

Is it possible for the cooling system to be air lock? If so how could I go about bleeding it. Is suspect this may be the problem.

Thanks in advance

Hi there,

remove a heater hose off the engine. Start filling the radiator untill water come out the block fitting for the heater hose, with water still flowing from hose connection block with finger and with heater tap open allow water to start flowing from hose, when flowing re fit to connection, tighten all clamps and run at low idle speed untill thermostat opens, Best to test thermostat as well, by placing in near boiling water on stove to make sure it is opening fully.
