Year: 1993
Make: Honda
Model: Civic EX
Engine Size: 1.6
Refrigerant Type: R-134a
Country of Origin: United States

Thanks for any assistance possible.

I understand that the 1993 Civic used the Sanden TRF090 compressor which is R12, and the 1994 and up models used Sanden TRS090 R134a. The car right now has the stock TRF090 compressor and converted to R134a. I'm wondering if I could just purchase a TRS090 compressor and it should still connect correctly? Or can the two not be swapped at all, and 1993 must use TRF090 and then be converted by hoses or what not to get R134.

Again, thank you.
