GT220 & RS265 Cooling System Diagrams

Now that I have limited access to Dialogys software I’ve been able to start working through the Parts catalog and establish what the differences are between the RS265 and GT220.  So far as “the Internet” already says they’re the same.

From the diagram you can see the oil/water heat exchanger and the supplemental coolant pump to circulate water through the turbo under various conditions.  To say the system is complicated is an understatement.

Over time I’ll get all the diagrams and parts lists working and maybe online.  But his is just a teaser before I get the Perfohub conversion parts lists completed.

How is that going?  well this morning I extracted the diagrams and over 100 part numbers for the “stock” GT220 setup.  It takes quite a while as each part needs to selected individually and transcribed.
