Just changed my radiator on my car as it had a nasty hole. Now is there a proper way of filling the system up?? like have i gotta "prime" the system? if so how??

Im gonna put in some anti freeze aswel, is there a particular ratio? like 20% anitifreeze 80% water?? And the water system is empty aswel cus as ive said ive just changed my radiator does that make a difference?

Id post this in the tech section but its dead in and id get a much faster answear in here

 

I always tend to run the car up to temp with the rad cap off and the heater on hot to try and get rid of any air locks. Make sure also that the nose of the car isn't pointing up hill.

 

I run 50/50 coolant and water, and as Pasty Palmer said, put the car on level ground, run the car up to temp with the header tank cap off and heaters on full blast for a few minutes then job done

 

i'd run more anti-freeze half/half ish and as said make sure u get all the air out,then check levels from cold a couple of times

 

as above but make sure you use 50% antifreeze and 50% water
