A/C repair and gas recharge / common problems discussion

[hassantahir2]

Bhai the key is to charge slowly and take your time just don't hurry in doing such stuff. The work done would be much better than roadside mechanic's.

I noticed that denso piston based compressor is putting load on engine. Do u recommend kabli denso scroll type compressor??
I want to do another experiment to increase fuel average.

[RehanBhatti]

Bro, are those adaptors universal which u used on gas Cans? Or they vary Can to Can?

Use a different main engine pulley.

Smaller outer diameter of main engine pulley (that rotates the AC compressor) decreases engine load and also decrease cooling slightly.

Great. Thank u for ur input.
Do u have FF denso compressor in ur khyber?

[RehanBhatti]

Its a tricky part buddy. I dont think so there will be any smaller main pully available for cultus efi.
How is denso scroll type compressor's performance compare to piston based?

Yes. Denso system is superb but that compressor puts a bit extra load on engine.

Easy to find, they are universal fitting. You have note the diameter of stock outer pulley and go for one inch smaller diameter AC pulley.

They are available in abundance for about 500. You just need to be aware of what size you want.

Check the displacement of scroll type compressor first. If you find some whose displacement is even better than stock denso piston compressor then that will work satisfactory. Usually the scroll type compressors available in junkyards are for small 660cc car's..

That so called duet ka kompresssooorr is useless above 40-42 degree centigrade..

Thanks for ur reply bro.
Does displacement written on compressors??

[RehanBhatti]

So, u r talking about compressor's pully or engine main pully??

[hassantahir2]

That's a tricky part..
You will have to check the model no. And then search that online to see the displacement of the said compressor.

[RehanBhatti]

Thats a good idea.
Do you have any tip to low FF compressor load on engine??
