take the top hose off and drain a bit of water,refill with the flush and put the hose back on
not sure why it says dont use the expansion tank tho

 

no idea mate why it says not to put it directly in the exspansion tank ? ,i think ile do what you said mate just to be on the safe side
cheers uby

 

cheers mushy , via the top hose then ?

 

that makes sense go for the top hose then,fill it slowly tho you dont want to get an air lock

 

what about coolant , surely that goes round the system when you add it via the exspansion tank ?

 

yea it does but probably not as consistant as through the radiator,it is solely theer to allow for expansion of the water and has a very small pipe to it from the top of the radiator and a not much thicker pipe from it to the engine area,i think using the top hose will circulate it much quicker with better flow

 

cheers neil ile give it a bash tomorow mate
