Does your car not break down/need enough maintenance then for your liking?! eek! wink
Get some jubilee clips, as Alfa use weird type crimp things which you have to break off, and usually involves stabbing your hand with a screw driver or pinching it with a pair of pliers. Just replace it with 'normal' ones, the pressure isnt high enough to use industrial strength ones!
If the rad is the same principal as the 156, on the bottom corner is a swivel joint for the bottom hose..which is a seperate part. If its not expensive, get a new one...or have fun taking the old one off!
And get a new O ring for it, the old one is guaranteed to get savagely destroyed in the removal process.
Thats if it is the same as the 156...
no manual/parts cd on me to check today...
Websites are like ********s, everyone has one, and im wary of any bloke trying to direct people into their's
On the Boxer this is a simple process alright.
Drain down and flush the system. See if there is a crud cleaner you can run through the system before installing the new rad, I have a few limescale deposits in my expansion tank.
I agree with AJ on the hose-clips, the Alfa ones are a sad joke! Pliers and hack-saw required for removal in some cases! Don't forget that this is your opertunity to replace any hoses which are soft/damaged also!!!...
And have the heater on full heat so you get full flow round the engine.
I'd recommend running on pure water (dont let it get too hot) and flushing it out and putting fresh in each day.
Do this for as long as you want (ideally 3-4 days), then fill it pure anti-freeze/coolant. It is not a big system, so it's not expensive to do. Also try and find one which is highest in Ethylene Glycol content.
The reason use water instead of a concentrated cleaner, is to save your gaskets from getting eaten away wink
