well the new radiator is in and seems to be working ok with no leaks. I ran the engine for half an hour and the temp was sitting just above the centre mark on the temp guage. I did have the yellow warning light on the dash though! I filled the radiator and opened the bleed screw next to the filler cap. I refilled the fluid level several times but the yellow warning light will not go off. eventually I looked into the filler cap and could see the small return flow of coolant comming out of the small hole in the side of the filler tube.
Do I need to do anything else to bleed the rest of the system - ie the heater hoses etc?
Will the yellow warning light eventually go off on its own?
I guess the yellow warning light is low level in the radiator?
