5A-FE Performance with AC On without running

[mujtabaayan]

As the subject show, please share your experience of 5A-FE engine in terms of heating in summers when car is parked or not running but AC is on. Does it perform equally good like running or heats up, degrades AC cooling etc

Depends on your system, if your cooling system is in good nick and engine operates at optimum temperature 82-85C then it should perform good btw your car should have Denso 10PA compressor it is very good and oldschool one use multiflow condenser for it charge quality refrigerant in exact amount and you're good to go.

Thanks for the response. Can I keep AC on for say 30 - 60 minutes when the car is not stationary.

@ahmedraja1996 Boss you have good experience in cars, regarding AC today I was discussing with a person that in my Nissan the guy removed the Nissan's original compressor and put SANDEN SD507 with old style condensor and I am not satisfied with its cooling. He said that he is having Corolla 2 with diesel engine and he too had rotary compressor in it and was fed up with its cooling. He says that my AC guy also did the same, removed the rotary and put in the sanden and then after that it was hard to let the AC on for long time because the cabin became so cool that even mirrors got frosted in the night drive and in day it was awesome.

I think his condensor was multiflow because it was original company fitted AC. Should I also try only changing the condensor or also put back the Nissan Original Compressor?

Qamar sb get Nissan B14 or N16 ac condenser it is multiflow and its best for R134a, old serpentine ones cannot cool R134a efficiently and you're having sanden 507 which is piston compressor and again which increases load on engine with serpentine one. Use original compressor of QG18 and buy a multiflow condenser for it and then see how it works.

This condenser comes in Nissan Sunny 2003 onwards.

Boss can I also use this condensor with sanden compressor? I am 110% sure that problem I m facing is because of condensor.

Yes you can use but your original compressor is better than SD-507.

What about the pressure switch? Isnt it necessary in case I use the QG18DE original compressor?
Currently SANDEN is running on juggar way i.e. VSV valve way not from ECU, so can I use the original one through this way and without pressure switch?

Yes it can be using it by bypassing it.
