flat4 to the floor

hi just need some help i have got hold of my new radiator for a 97 classic,however i am fully capable of fitting the new one but need to know how to fill it,as other than the main header tank under the passenger wing there is another bottle is this an overflow or does it need to be filled to the maximum line that is on it,prior to this i was a ford man so never had this extra tank or bottle whatever it is.so any help would be greatly recieved,many thanks karl.

fill up the header tank slowly so as to expell any air when filling, the plastic reservoir at the front is for when the engine is warm or cold ie engine lets water out when warm that it doesnt need and when cold takes it back fill that to the max line then after your done filling header tank start engine let it get up to temp switch off leave to cool and check reservoir it should be between min and max if not top it up job done.

Its an overflow tank i think, you should fill it up via the main header tank, leave the cap off when filling up and wait for the thermostate to open up, then let it idle and let it circulate the air out via the main header tank, you should see bubbles at some point, this might take 10 minutes or so

anyway thats the way i do it when i need to fill up

hope that helps
