Coolant Change

[Mick]

Damn almost a year ago now i had the turbo off the car and i just let the water lines dangle there after i undone them from the turbo, when i put the turbo back on i just bolted the water lines back up and thought nothing of it, now i read stuff about getting air in your coolant system. The car has run fine even though i didnt try to bleed it, i guess i just must have been lucky not to have got air in the system then ..

So anyways with changing the coolant i read the workshop manual and it doesnt say anything about bleeding the air by opening the air valve while the car is running like ive read in a few threads here. So can anyone shead some light on this cos the workshop manual just says top open the air valve while filling up the radiator and to close it if coolant starts coming out of it, and then it says that when its filled up to close tha valve and then start the car etc etc etc .. nothing about opening it while the car is idling.

This is what you should do : ignition on climate control on the highest temp , undo the bleeder fill the radiator until coolant comes from bleeder , do it up and fill the bottle .

Start the engine until normal temp ( thermostat opens ) , let it cool down , then take the radiator cap off and top up , check the bottle and if down fill .

No dramas if you dont open the bleeder , it just means that you will have to put more coolant in after it cools down , the system will bleed itself . It will be fine as long as you top it up , the bleeder is there to make it easier .
