How to purge air from the radiator
normally the radiator will purge itself as long as the overflow jug remains at the recommended level. warm eng to normal operating temp if you have no leaks it should draw water as needed from the overflow jug when you shut the eng off .. it may take a few times of starting and stopping eng but this method does work.. careful as the radiator fluid is very HOT !!! if no overflow jug is in your system go to highest rad. hose and open the system there.only do this when eng is cool. slowly fill radiator at the cap holding the hose you remove higher than the cap. a helper is needed for this procedure. starting at btm rad hose gently squeeze entire length of hose working your way to the next lowest hose do the same procedure for each hose. heater hoses also need be done reattach hose start eng let idle till normal operatin temp is reached turn heater to full heat . let eng cool then chk level of rad. repeat as needed. good luck .TIP : be patient .
