1980 Yota,everything checks out with my mechanic..don't notice much difference when idling or on the road.Thanks for the reply.
If everything "checks out" then you shouldnt be having a problem. Either the referigerant level is not correct or the compressor is not working to its full potiential assuming your condenser and evaporator dont have any contaminants such as dirt or leaves that would be decreasing their effective heat transfer areas.
While I agree R-134 does not cool as well as the old R-12 I have converted numerous vehicles to R-134 and have never had one that didnt get cold enough for th customer. If you think its not cold enough then there is something wrong with the system regardless of whether it has R-134 or R-12 IMHO.
