Reply With Quoteextended nose was to allow a harrison[GM] a/c system.this was standard on australian county.its not in the UK parts books.
the system is from USA or canada depending on who you ask.not that good-its actually probably very good in canada.the system has a old large R12 sepentine condencor and a range rover type twin electric fans.to allow room to fit this in the bonet lock stay is changed and the extended nose is to allow for the fan and stay assembly.
V8 used the 4 piston GM compressor,the 4BD1 uses a old SD508 sanden pump.the hoses are not the easiest to fit as they are modified in V8 pipes.
some cab chasis are fitted with the condencor and compressor and roof top or an AMC evaporator.
there are different non A/C alloy panels for different climates.some with 1 or 2 added holes at the bottom.
after australian assembly finished defenders use AMC systems fitted by the dealer.these are not UK supplied.the sanden parralel flow R134A condencor and fan is rarebut is made up of parts from another cheep to obtain car.slight cutting is reqired and a saftey lock protection plate to fit this unit.
this modern unit is small and very efective.the tubes run across 5-10 at a run allowing the liquid to fall to the bottom.however you cant repair of clean these and they should be checked with a laser temp gun for restrictions.
