and I stand by my common sense answer, it doesn’t have an oil cooler, don’t just continue to ride it until parts and repair are done. Which you keep missing that point, no compressed obviously

no M8 non twin cooled Touring engines, which is the subject and topic at hand ..weak attempt...Next!!!

you know OP..never mind me..take the advice of all these Internet forum subject matter experts and feel free to ride your brand new under warranty $35,000 liquid cooled bike with coolant system failure until they can get it repaired, because these folks here say it will be ok, doesn't need an oil cooler and it'll handle all that just fine...

Yup. Had a friend lose the pump,on a trip. Dealer told him to keep on riding.

Please tell me where it says in the service manual that this is a liquid cooled motorcycle. Like I said before know what you're talking about before you give advice.

they call it twin cooled because it's both air and liquid cooled..they added the liquid cooling because it cools the hottest area of their motors..they obviously determined that was needed....the oil cooled engines are air and oil so twin cooled as well..the oil cools the same are of concern...you dishing out the advise for someone to just continue to ride their bike with an engine cooling failure makes you sound real knowledgeable, especially now during Summer riding season

See if the dealer will give you a loaner, or if they do the rental program, one of those. Call corporate ASAP and tell them whats up...do you have the harley ESP coverage? maybe something there to help you continue on your trek? SUCKS!!!

OP, do you or did the dealer know for a fact that coolant is actually leaking from the radiator and not from somewhere else?

Obviously, since you were in Salida, Co, you were 7,000+ feet and maybe higher if you rode over any other mountain ranges.

I wonder if the altitude may have caused an overflow of the coolant, perhaps from the pressure cap?

Did the coolant continue leaking once you were lower in elevation?
