Time for antifreeze in my car

as the weather is now getting colder i need to put antifreeze in my car, but in the books i have with the car it do not say anything about the = amount that i should use.

i have a 2002 1.6 8v astra estate. do anyone know how much antifreeze i need? and what is the best way to drain the system?

is there anything i should check afterwards for say air blocks? what = about the heater ?

that i should use.

I would remove the radiator and flush it thoroughly, that will solve the draining question, replace the radiator. Then empty between 1 and 2 litres of new antifreeze into the header tank, top up with fresh water (about anither 2 to 3 litres), and start the engine. Lots of glug glug glud as you massage the radiator hoses will force out the air. Then a road run to circulate the whole system.

At laeast that's what I do on my 1994 Astra 1.6GLS (8V)

that i should use.

Is there none in there now?

If not, why not? Antifreeze should be in it all year round. It cannot be stressed highly enough if your car has an alloy head and block that this should be the case.

That's probably because it's not a winter only thing these days but should be used all year round to prevent corrosion. And if the car has been properly serviced you need take no action.

looking at the water colour i would say no i dont think there is, had the car repaired at the beginning of may, and i dont think they = replaced it. i wont be going back there again .

According to Comma the coolant capacity is 6 litres (or 6.5 if fitted with Air con). It says from May 01 use red antifreeze at 50% mix. If it uses red I don't think you can mix that with the green or blue stuff.

thanks m8. i will drain off the water and add 4 litres of antifreeze before topping = up with water..
