Ami faces are a ball-ache to whip off quickly.... Whilst it's true that I'd forgotten we were talking Ami, on an 8/Super it's not that bad to just remove the grille. I swapped the plastic of the fan on the Super through the grille once. Yes, just the plastic - which attaches to the backing plate in a very similar way to 2cv - except the fan is bolted to the crank with a driveshaft-kinda-size-nut done up to rear-hub-kinda-torque... yes, but laziness or innovation???  i'm only joking.... i could try do that i've seen a picture somewhere of the whole front of a 6 off in one piece, possibly with inner wings too. Can't help thinking it would be wobbling all over the place, but would be very handy... thanks again

 Re: Cleaning the oil cooler in situ
Will, I'm not too sure that it's the alternator belt which produces all the crud that ends up blocking the fins of an oil cooler... For one thing, the belt would have to wear at a rather alarming rate and secondly, the layer of road dirt often seems to be thinner where the belt has shielded the oil cooler from dust laden air being propelled towards it. My favourite weapons for cleaning an oil cooler are an old spray gun filled with petrol, plus a blow gun to 'tidy up' after the first pass with the spray gun. The air pressure needs to be turned down when using the blow gun, to avoid any chance of distorting the thin alloy fins. The wearing of goggles is mandatory, of course. ken.

 Re: Cleaning the oil cooler in situ
You can get to it on a 6 no problems. Two wingnuts and an 8mm nut to remove the grille, then the fan's no harder than any other A series. You can take the front panel off in one go, the inner wings are best left on though, otherwise you're looking at removing the outer wings, bonnet and stuff, which is a waste of time just for cleaning the fan. To get the front off take the two 8mm head bolts out of the little struts, the two Phillips screws from the bottom of the front wings, the two bolts holding each side of the bumper to the front panel, the 12mm bolts holding the overrider to the chassis, and the two bolts holding the front panel to the inner wings. Slacken the headlamp adjusters and remove them from headlamps, undo bonnet release from the cable joiner on the inner wing, and then remove front panel. Then, replace it and undo the multitude of fixings I've forgotten to tell you about.
Or, save yourself time and stress and just do it through the grille aperture...

 Re: Cleaning the oil cooler in situ
It's actually quoted in the "Maintenence Guide" [book of stampy thingies] for my old 1975 Dyane. >every 6000miles "Blow the oil cooler fins clean (with compressed air)"< Oddly .....there's no mention of it in the Maintenence Guide for my 1988 2CV ...... [:roll: and oddly,by 1988 the service intervals had altered from 3000,6000,9000 & 12000 miles to 5000 & 10000miles  .....now there's progress for you ....  ] T.

 Re: Cleaning the oil cooler in situ
James, might be an idea to turn the pressure down a bit next time. Those alloy fins can be a bit fragile and may bend if too much air pressure is used. Even more caution is needed with a pressure washer... ken Jameswallace wrote: cleaned mine when i serviced it, as i was doing the points also so had fan off anyway few dead flies and that, blew through with compressed air, with the compresser at about 115 psi ish! clean as a whistle
