    which city you are located? - In Karachi magazine lane behind plaza spare parts market have plenty of radiator shops. Before you change radiator flush the cooling system get rust out flow out use coolant prepared in bottled water read here how to flush cooling system.

    Corolla 1980 is a rear wheel drive - the engine have mechanical clutch type radiator fan, not electrical one. - radiator cooling electrical fans started with launch of front wheel drives

    flush the system get radiator cleaned & change radiator cap, use coolant prepared in bottled water. also check the hose pipes for any cracks, change with new. read here what Xulfiqar suggested for revitalising the mechanical cooling fan

    In my opinion, you should first get your radiator serviced, change the radiator cap and then fill it with a proper coolant.

    Nothing more is required, as I hope it should work...

    You can most probably buy a ready made radiator from magazine lane Karachi, it would be twin pass radiator - make sure you tell them its for a 1980 corolla and not a 1982 corolla because the top radiator pipe is at the different position in the 1982. Its a 30 minute job to replace the radiator in your car as the shroud is 2 piece, once undone the radiator is unbolted (4 bolts) from the frame and slid up and out. make sure to get the correct design fins for maximum cooling efficiency.

    This applies only if you have the general imported model corolla which was simply called toyota corolla or corolla DX, If you have the later JDM import called SE or GL model (huge bumpers) then your radiator MAYBE offset to the side of the car and have electric fan.

    I doubt your engine will have the clutched fan as most general imports had the silly looking 4 blade fan in a gigantic air shroud. Later on mechanics replaced it with either a 6 or 7 blade fan which caused enough air noise to challenge a dump truck.

    you can opt to install a clutched fan, it requires replacement of the shroud for the larger fan and also mounting of the clutch on the waterpump pulley. Make sure you service it first, its silicone oil is sold as a spare part in little bottles.

    Always use a genuine thermostat valve and radiator cap and make sure the expansion bottle is connected with no leaks in the pipe. The needle being in the middle is normal position, if your system was boiling out then you have some leaks.

    Interesting reply by Xulfiqar, I remember the A/C walas recommended fans with more blades for better cooling and the last one they installed consisted of 8 blades, the damn thing put too much stress on the engine and resulted in increased vibration and poor acceleration.

    We got an electric fan setup in the end, the apparatus of course wasn't perfect as the thermostatic fan switch was from some other car and didn't keep the temp as per manufacturers spec but resulted in smoother and faster acceleration.
