Re: Milano Aux radiator fan

[Steve An <stevean@domain.elided>]

Alan,

I had all the same problems this summer. I have a Milano Silver with a 3.0 
Verde engine and a newly recharged AC.

I concur with AlfaBill about the need for a good working radiator. It was 
the last thing we replaced, because I thought it looks OK (don't ask me 
why? I am a moron), we replaced the thermostat, sender, water wetter etc... 
none made any appreciable difference, OK on the highway, overheats in town 
on hot days with AC on; finally we decided a new radiator is a good idea, 
it made all the difference in the world.

I had a spare 9" slim fan laying around my garage, so we also installed it 
in front of the radiator, wired to the AC for additional cooling. I am not 
sure if this was necessary but I thought it couldn't hurt. And after years 
of living with temperamental cooling in this car, I had assumed that it is 
just under cooled from Arese, but I now think it is adequate, if not Lexus 
like. The electric aux fan has got to help the efficiency of the AC, 
though, it blow wicked cool air.

The original fan is a puller (suck) type, it sucks the air through the 
radiator, thus it sits behind the radiator. If you want to install a fan in 
front of the radiator, it has to be the push (blow) type, the biggest that 
would fit into that space is about 10" with about 2.5" depth, fairly hard 
to find.  Basically, get the slimmest fan you could find, 9" is great. It's 
hard to physically get the fan to fit into that space from the opening 
under the car's front valance. You simply can't get it in there through the 
front grill opening.

You will need to fabricate the brackets to hold the fan onto the radiator 
and wire it into the AC relay on the passenger sidewall of the engine.

I'd replace the radiator and the thermostat (may have been fried if the car 
overheats) first before I do anything else. The radiator is only $250, not 
pocket change, but money very well spent.

cheers,

        - Steve.
