hi, engage
I don't mind discussing this with the forum, I just meant I'm done fiddling around with Triumph. I agree with you that Triumph undoubtedly doesn't know the answer. I know you're a techie, I'm a techie. I did lots of jobs just like this for Dupont...among other things lead design on the Quad4 plastic intake manifold. I know what they should have done, and what they more likely actually did. And we could talk about that in much more detail. My point of contention is not with their analysis and/or testing (and lack thereof)...my point is that if they are going to sell a machine and a warrantee, then they have a moral if not legal responsibility to describe explicitly what the buyer's obligations are to maintain that warrantee. That's it as far as I'm concerned. You can't "suggest" one coolant and then have all your dealerships actually filling up someone's bike with a different coolant without clarifying what the heck is going on. I don't even care which way they go with it, just a little consistency and integrity would be nice.
regards,
John

Reviving an old thread.

From what I can tell through research, a suitable substitute for Triumph HD4X is a G-05 coolant.

Most important characteristics of HD4X:
  • HOAT
  • Low Silicate
  • High Nitrite

Description of Zerex G05 on Valvoline/Zerex website:

ZEREX™ G-05™ is the automaker approved original chemistry used in newer Ford, Chrysler and Mercedes-Benz automotive and diesel engines. Its Hybrid Organic Acid Technology (HOAT) chemistry combines the best of conventional and organic acid-based chemistry to provide the ultimate protection against rust and corrosion. ZEREX G-05 antifreeze/coolant uses the highest quality virgin ethylene glycol for freeze and boilover protection and a hybrid organic acid corrosion inhibitor package to protect your engines from liner pitting and corrosion.

Description from the Amazon website:
  • The formulation is designed for both gasoline and diesel engines
  • Its lower-silicate, reduced pH, phosphate free European technology protects all cooling system metals, including aluminum, from corrosion
  • ZEREX G-05 is a nitrite containing coolant designed to protect diesel engine cylinder liners from cavitation. It contains deposit control additives for protection from hard water deposits and scale
  • ZEREX G-05 contains a high quality defoamer system and will not harm hoses, plastics or original vehicle finishes

Is there a forum consensus on this subject and am I going in the right direction with G-05?

My bike is 5 years old and I'm its new owner. I have no idea when the cooling system was last serviced, if ever. So I need to get it drained and flushed in this riding season.

I puzzled over the same issue when I went to replace the coolant in my (new to me) 2010 TB. I also suspect it had not been changed in several years. A few thoughts: (1) the old coolant looked fine - no crud; (2) the consensus seemed to be to use Zerex G-05 - I bought concentrate and diluted 50% with Walmart distilled water - less costly than pre-diluted and leaves enough for future top-offs; (3) I found it easiest to simply loosen the lower hose connector, open the radiator pressure cap, and squeeze a thin screw driver between the hose and the radiator outlet to let coolant drain out - drains more slowly but much easier than trying to actually remove the lower hose; (4) do not forget to empty the radiator overflow reservoir - easiest to do using a small hand pump; (5) rinse the system using distilled water and drain till no color shows; (6) when refilling with fresh coolant I found it best to fill from the "air bleed vent - remove bolt and connect funnel with hose over the nipple - this way the air vents out of the radiator fill cap which is the highest point; (7) close up and run engine for a few minutes before trying to add more fluid via the bleed nipple as previous to ensure all air expelled; (8) top off the expansion tank to full mark using a the hand pump again; (9) fit a new sealing washer on the air bleed bolt before final tightening.. Hope this helps!!
