Heres the radiator from front on. AM I right in saying its still almost completley blocked. Theres a patch near the middle that looks somewhat unblocked. is the whole radiator ment to look like that one patch?
No one can tell if it is blocked with the pics you are posting.
As you have the fan off, get a small mirror (3 or 4" mirror from a make-up compact is good) and a flashlight. Shine the light through from the front and use the mirror behind the radiator to see if you can see through every crack and crevice. None 'should' be blocked but some are bound to be.
If you have 3 hands or a light on a stand, you can even take pics of the view through the mirror from the side. Simples!
It is OK to use wooden toothpicks/cocktail sticks to poke through the crud but don't use anything metallic. Old toothbrushes are OK (assuming you have old teeth) for lihtly scrubbing and wiggling in the crooks and nannies. Remember, the radiator core is aluminium and is easily damaged.
Also, you will have realised how much of a pig it is to get the top bolt (? Can't remember if it the top or bottom) out of the fan mount on the right hand side. While it is out, file flats on it so you can use a Spaniard to tighten it back up rather than fiddling with the screwdriver at a gawd-awful angle. Brian
