Coolant hose chart

All,
Attached is my new Syncro Coolant Hoses chart, I hope it is self explanatory. In most cases, I've tried to orient the hose pics so they look on the chart as one would normally eyeball them in situ, my objective being to make them more recognisable. Please print in colour for easier reference ... also a novel attempt is the G12+ coolant colour in the side title box.
 
My extreme appreciation to Roger Bayley for his time and effort in supplying and confirming hose diameters, lengths, angles etc.
 
Also attached is ETKA coolant system illustration 16-17 and associated parts list. Sorry about the blurry numbering on the ETKA diagram ... out of my control, something to do with file conversion bug. I suggest this be printed also and then using the "Where's Wally" approach, re-mark the ETKA position numbers more clearly with a biro. The only hose not numbered or listed on 16-17 is ETKA hose 25, its details are on ETKA water pump illustration 16-07. However hose 25 is at least partly shown on illustration 16-17 albeit obscured by hose 28. It's directly underneath and roughly at mid length along hose 28. 

 
My study concludes hoses 9 and 26A handle opposing direction flows, dependant upon open or closed thermostat. Hose 18 is one direction only but either returns or feeds reticulation, again dependant upon open or closed thermostat. For the rest, the hose descriptions indicate coolant direction, either "return" (cool) or "feed" (hot and passing through hose 26 toward radiator).

To follow my logic for hose descriptions, I started at return hose 16 (reference ETKA illustration 16-17 here). Exiting the radiator, this is where the coolant reticulation starts as cool. Then I simply followed the reticulation, picking up the hoses as I went till I ended back at the radiator with hot feed hose 15. For easier comprehension, it's handy to have both the chart and ETKA illustration 16-17 side by side.

 
Equivalent to connectivity/functionality of hose 18 for RHS cylinders, there is similar for LHS cylinders. However this is coupled to the thermostat housing. So with no rubber hose link, then llustration 16-17 is somewhat obscure on this reticulation.
 
The only coolant hoses not included on the chart/study are those concerning reticulation to/from the heater.

I think my understanding of the syncro coolant reticulation system has progressed from dense fog to pesky mist. I agree it's complex but also pretty ingeneous when one studies it more fully. I wouldn't discount their remains more to learn on this topic.

 
For those who don't receive syncro forum posts into own email mailbox, I'll add these files to the forum files section.

 
Cheers.
 
Ken

Good work, Ken.

I'll add it to my manuals disk.
