What coolant and how much
 

Draining my rad to replace the bottom hose.
so will be refilling the complete system.
what do people use (colour/make)and how much do I need.
Thanks

mix would depend on the exact brand but a good quality BT from Millers requires a 33% mix so approx 3ltrs of a/freeze and 4lts of water

do NOT be tempted down the higher concentrate is best route as a/freeze is a poor coolant and will actually cause higher temps in similiar way that the "waterless" coolants dont work.........
