notes from P400S parts book -
starting with motor #2706 the fan motors, brackets and support rubber were changed
MW-05166 round motor (9GM 54071553 B) replaces MW-01546
bracket replaces MW-03595
are added to mounts as the bolts were smaller and required this rubber bushing.

Feb 16, 05 - I dropped off my car last week at Bobileff's to deal with some fuel system issues (my carbs were spilling fuel all over, turns out one of the floats failed and sunk). While the car was there I asked Gary to pull the radiator to rod it out, as a preventative measure (the car exhibited some slight overheating last summer when I first got it). Today I got a call back from him saying that the radiator people indicated that the radiator core was shot. I now need to recore the radiator or find a new one/replacement. Anyone now where I can get a low interest 3rd on my house? (Just kidding).  I will be calling GTC tomorrow morning to see if they have any replacements and cost. Any one have any other potential leads to a replacement? Thanks. ..Alberto

You can order one direct from lamborghini still. Part # is still good: miura cooling - radiator tav 13 1703597 Coolant Radiator $1,976.72  Dealers cost on this part is $1231.63,  .."knjw1"

Ridicolous! There are radiator companies which will replace the core for about $500. I have a Miura owner here in Switzerland who had it replaced for that amount, also an Espada owner, both were amazed with the result. There are new modern cores which perform much better, the miura owner owns a company which makes the marks on the streets. This marking machines are runnning the whole day but with very low move, they have special cores for fork lifts, extremly efficient. Install those cores and you will never have any overheating again... Raymond

The thread about radiators and cooling made me remember that not everybody in the world knows about Peter Economoff.  Peter owns and operates Peterbuilt Radiators in Santa Barbara. Over the  years, he have proven to be a valuable resource whenever you have a radiator issue to deal with. The oil coolers on the 400GTs are extremely vulnerable to damage thanks to their location in the lower front of the car. One dip or oversized speed bump can ruin your day! I have had two oil coolers manufactured by Peter over the years. The are indistinguishable from original and very efficient. He has the capability to build from scratch, virtually any kind of radiator. Before it was virtually destroyed in the big Santa Barbara fire some years back, Jon Rand's SV had been equipped with a custom air conditioning system by Peter that was an engineering marvel. He is an extremely talented man.
For Espadas and most of the older cars, Peter can build a cross-flow, aluminum radiator that he says is 30% more efficient than stock. I have found over the years that his prices are very reasonable. Right now, he is re-manufacturing the two condensor units that the 400's equipped with air conditioner have shoe-horned behind the headlights. Mine were trashed and you can't get those units anywhere. And the original equipment units had a problem with tube breakage which Peter can fix.  Here are his vitals:
