OPEL CORSA B Sedan 1.6 IE 1999.
I would like to flush the coolant and bleed my brakes.
For the coolant, I have bought German HEPU antifreeze, Anyways, I only have a reservoir bottle and I do not have a radiator cap.I have a garden hose and a funnel and a drain pan.
How do you flush the coolant with only access to the expansion tank? Do you just stick the hose pipe with medium pressure in to the reservoir bottle, after it starts circulating (if it actually does) I can start the car and watch the temperature, then turn on the heater and the fan on 4 for a while, and continue the hose pipe flush. I would reckon a whole 10-15 minutes of this procedure. **
Can i use the German HEPU (96 % percent antifreeze) coolant alone and with no water - so i.e can you in general use antifreeze alone with no water?
We get like -10 maybe worst case and up to +35 degrees Centigrade.
Does my flush procedure sound correct?
Is it okay to use antifreeze alone?
