HDI 110 Cooling system drain and refill

[adam03031980]

Hi All

I am replacing the coolant in my system with some premium red but wondered if anyone can tell me if there are any bleed screws on the engine, it currently has green coolant in but I am worried I may not be able to get all that out can anyone advise how it can be done the only thing I found was a 2 plugs one at the bottom and one at the tope of the radiator. And one last thing why has my engine fan never cut in i have had the car 4 years and not once has it come on. Th temp always sits at 85ish

My method is to stick water in, bleed, run until hot, bleed, wait until cool, empty. Repeat until water coming out is clear

There's a blue one at the side of the thermostat housing and one on the heater pipe at the back of the engine.
Open the screw on top of the radiator and fill until water floods out, screw it back in then undo the blue one and the black one on the heater pipe, pour water/antifreeze in until water floods out of both then run the engine, constantly opening the black one until water floods out, when the engine warms up, undo the blue one until water floods out constantly.
