Bleeding



When sealant dries its time to fill the system and bleed it.

Bleed niple is on heater pipe, the other one is on the radiator (behind right headlight).

Fill expansion tank to the top and open bleed nipple on radiator and wait till a clear stream of coolant comes out, do the same on heater pipe nipple and drop coolant to max through nipple, start car run till fan comes on, turn off car and let it cool, top up if necessary to max. If you get no hot air commin through vents it means there is still air trapped inside so you have to repeat bleeding procedure.
