I'm looking for some guidance on when to replace the hoses and thermostat on the 1800 Goldwing. I have a 2001 model with 33,000 miles on it. The coolant was replaced back in 2005 and now that the bike is 8 years old, I assume it's time for hose replacement. Would you replace every hose or are there some you might let go a little longer? Since you have to remove the water pump assembly to replace the thermostat, would you bother replacing the thermostat if everything had been working well up to this point? And for those of you who have done this service, what kind of problems did you encounter or what would you do different next time? Thanks for any advice.

Me too! But I think most get rid of before doing so.

For most autos, it recommended that coolant and hoses be changed every 4 years, or 100K miles..whichever comes 1st. As for the thermostat....if it ain't broke don't fix it. I have gotten well over 200 miles on the original factory thermostat in my trucks. I use Fail Safe brand whenever I need to replace one and if available for the vehicle. Fail Safe will always stick open if and when it fails.

With such low mileage I would just inspect once a year, for the hoses. If when you do a coolant change and all is well I would leave well enough alone. I wouldn't worry too much about the other.

But if you are going to go that far into the engine and you want to replace the other hoses, then I would do them all at one time. It is a time consuming job and you know to get to the hoses you will have to remove the fuel tank? If you can do the work yourself it will save you a lot of money over what the dealer will charge you. But it never hurts to ask what they will charge to do that service for you. At least you can be prepared when you decide to do it.

Hope this helps.

My 18 year old this year 91 Venture has never had a hose replaced. I asked the mechanic at the dealer if I should replace them and he said no. He's never seen one fail. I asked on the Venture site and couldn't find anyone who has had a problem with a hose.

I put 190K miles on my GL1100, never replaced a hose. I put 240K miles on my GL1500, never replaced a hose. My GL1800 has 130K miles on it, and no hoses have been replaced. In fact I never replaced a water pump, T-stat or radiator cap on any of them. The only caveat I will make is that I ran a zero pressure coolant system in each bike with Evans coolant. The hoses were not subjected to constant pressure expansion and contraction each day.

Heavens no, your bike is nearly new with few miles, wear or punishment. You should have a long long time before you need to worry about fooling around with any of the 32 hose clamps on the 1800, nor would I suspect you would want to given where they are all located and how you would have to get to them all.

Replace your coolant, check for leaks and enjoy your bike. It's still new.

That is a really tough question to answer. Many of us have had hoses blow out in our cars. But on motorcycles, they seem to last forever. My 17 year old Honda Magna with 55,000 miles on it never had the hoses replaced. From the outside, they looked like new, without any evidence of dry rotting.

I have an 02 with over 50,000 miles, and I don't intend on replacing them for quite some time.

Replacing all the hoses would be a nightmare job!:eek:4:

At 33k miles, I wouldn't give it a second thought.

Don't worry, enjoy the ride :lol:

Come on guys, we had a deal, no one was to agree with me until 2013. Why is everyone forgetting the deal ?? Just because Obama got elected does not mean that contract is null and void !!

Thanks all of you for your input on this subject. I'm usually a preventative maintenance kind of guy but I was afraid of opening a can of worms replacing all of the hoses and possibly having leaks where none existed before. So I think I will drain and flush the cooling system and install new coolant, saving some money, time and frustration. Thanks again

"Can of worms." A fitting metaphor indeed!
