Anyone know where there is a guide to doing this? Looked at wiki...no joy. I know its probably simple but just wondering on refilling without getting air trapped etc? any help would be appreciated! Thanks

 

Once you refit the new one, fill up the header tank and tube tank to the max, squeezing bottom rad pipe to help get as much coolant in as poss. Re- fit cap.

Fire up the moter and let it run till it shows temp increase on the gauge then switch off and leave for a few minutes before re-filling both tanks again, squeeze rad pipe again to help any air rise. Re-fit cap.

Fire up again and run for a few mins, switch off re-check levels, top up if needed, re-fit cap...Sorted

Never had any bother with trapped air on a impreza...

 

remove the header tank cap... fill in coolant water mix...

when its full

i always had squeeze the upper radiator rubber hose to get all air away...

than again fill in coolant water until its really full

on the impreza its really simple

 

Thanks chaps
