Hi!
Looking to mount an extra under tunnel radiator on my Nytro RTX, just like the one on the stock MTX.
Where do I connect it to the line of coolant? Where is the side-mounted under tunnel radiator connected to the line of coolant on the MTX?
According to the exploded wiev, I should connect it to the line that goes directly from the wind-radiator to the front-tunnel-radiator.
Correct? Any input on this regarding optimal cooling and direction of coolant flow?

What kind of conditions do you normally ride in? If you think you may have some cooling issues, try testing the anti-freeze that is currently in it now. All mew Yamahas are shipped with 100% anti-freeze, and changing the mixture to a 50/50 water mix will help the cooling system function better.

Yamaha recommends a 60/40 mix of ethylene glycol-based antifreeze to clean, distilled water.
If you’re having problems with overheating now you may want to check that all air has been purged from the cooling system before adding the MTX tunnel heat exchanger. Air trapped in the cooling system inhibits heat transfer between the engine and coolant and reduces its efficiency. Both the owner’s and service manuals have instructions for this simple procedure.
You’re correct about the connection for the auxiliary heat exchanger. It taps into the line between the radiator and the tunnel exchanger. If I were going to do this, I’d extend the lines and mount the exchanger at the rear of the tunnel to, maybe, help reduce ice build-up.

Great confirmation, I wasn´t all wrong then about the colant line and where to "jack in" the extra radiator. Also, it´s mounted further back in the tunnel than the MTX is.
I´m running 99% off trail, but since the rest of this RTX is no more RTX I felt I had to do something about it! -> Going to a Summit skid w a 16x151x2 track as a starter...and WILL need the extra cooling when the spring comes.
No worries about the coolant mixture, I will have enough cooling anyway.

tunnel exchanger
The top hose off of the mtx tunnel cooler goes to the air cooled radiator ( bottom connection ) while the bottom line on the mtx cooler connects to the bulkhead cooler.
You will not have heating problems after this cooler is in, just make sure to get all the air out ( just get the front end a little higher than the rear and shake it around some )
