DougFallin Posted September 6, 2025 Posted September 6, 2025 (edited) I have the pictured A/C compressor. If it is a Sanden, I think it's a SD510HD model. Can someone correct me if I'm wrong and suggest a source for replacement in a R134a model. The one pictured is a converted R12. One of the mounting points broke and Im looking to upgrade, if possible. Thx, Doug Edited September 6, 2025 by DougFallin Misspelling Quote
extech Posted September 7, 2025 Posted September 7, 2025 don't think theres a difference in compressors for 134 and r12. just the charge ports and oil type Quote
Ssunrader Posted September 7, 2025 Posted September 7, 2025 Correct, only that the r134 will require PAG oil. Denso makes a new replacement compressor but it comes pre-oiled with the wrong oil. You just need to buy an extra can of PAG oil and do a good flush before installing it. Quote
