RESTORING A CLASSIC 1970’S FRONT ENGINED V-12 FERRARI

 

The original refrigerant, Freon 12 gas, is no longer available in the UK or worldwide. The hose on the inner side of the right front wing near the air con drier, with a copper water pipe repair, is the hose from the  brake servo unit to the   camshaft driven brake vacuum pump. These sort of botch repairs were evident in many areas on the car The air con  pump is driven  by a key at the front  by the  right hand intake valve camshaft.

The first attempt to re-gas the system failed completely  because of a fractured  copper pipe at the  the evaporator inside the car. which was repaired prior  to putting the  unit put  back in the car. The pressure & nature of the cooling gas found other leaks & the evaporator had to be removed & repaired again. Second time was successful & the air con system is now back in the car & working.

 

The Borletti air conditioning system was completely  ineffective & probably not working at all. If it had worked in the recent past the flexible  piping was  so well worn that  the system was  not retaining much gas.The air con radiator did not  retain any  pressure & it would  be necessary to repair & renew all of the parts I could obtain or make .  The Aspera York compressor  & the electromagnetic clutch was overhauled by Polar Air  UK & fitted with new ports for current coolant gas. 

The replacement  ventilation hose is an exact replica of the original but it is far too new & clean to look that way.I hope with time & use it will ‘grubby up” & look more authentic.

The purifier desiccator  is a key component of the system & was badly battered. It was also almost full of  water & I could not drain or dry out the crystals. A replacement unit was available at Ferrari UK & was fitted after cleaning & re commissioning the various solenoids & parts of the system

The air con radiator was cracked & leaking gas & was beyond repair.It was replaced with an identical unit that was again available at Ferrari UK.I was getting use d to the Ferrari term  NLA (no longer available) so was pleasantly surprised at the off the  shelf  availability of so many items

Heating of the car is provided by a complicated yet inefficient system with a small hot water radiator situated either side in the engine compartment deep in the depths of the internal wing area.

Hot water passes through  a complicated system of hot water pipes that from the front hot water radiator to the rear of the engine block through the two individual heating system radiators.

Hot water flow & therefore temperature is controlled by a valve each side near the heater radiator controlled from the dashboard ski slope.
