So this will be my official progress thread as I attempt to make the best A/C system possible using only factory parts.
My 300TE is currently switched to r134a and it just doesn't cut it out here in Arizona.
Parts to upgrade:
Old 15cc to New 17cc Denso Compressor
Larger Condenser
Twin fan assembly
New Drier
R12 refrigerant
So basically, Mercedes used a larger condenser, larger compressor and better twin fan design to improve on the shortcomings of factory r134a system.
If I upgrade to that design, BUT use R12. How could it possibly get any better, right?

So went to the junkyard today and found a complete assembly with working fans (tested using portable battery).
The Fan and condenser should be easy....The only problem I think I will run into will be with the different placement of the hoses as shown below:

Compressor Hose:

Does the 17cc compressor REQUIRE the later hose, or will the original one fit? Anybody know?
