14 year old Coolant Hoses?
Haven't been around for a while but Ive always looked to the forum and its members for reliable advice.
A quick refresh - (or take a look at my post history for more about me and my bike.)
06 with 50500 miles always garaged, routine maintenance performed yearly, ridden regularly never stored or neglected since I began ownership at 28000.
I have a small leak at the thermostat housing and the short hose that is attached to the metal half of that housing. The housing is a bit crusty at its junction of the two halves and the hose seems to be weeping small amounts of coolant from its ends and/or the inner reinforcing fiber after a ride. It stays dry until after a ride and the bike is shut off. No drips on the ground no measurable loss of fluid.
Obviously I will be replacing the thermostat and hose. I have the lower plastic off of one side and am able to inspect all related coolant hoses and they all appear to be in very good condition with no bulging or evidence of leaks.
However, they do appear to be original from the factory but really no way to confirm. If they are original, they are in great shape but 14 years old. There is nothing in the service records from the previous owner indicating that they have ever been replaced. I have owned the bike for 4 years.
Yamaha dealership is recommending that I replace all of them including the clamps? and says the service interval for replacement is, wait for it... 4 years.
I'll be doing the work myself and dont mind replacing all of them if it is necessary. What I dont want to do is risk breaking delicate radiator inlets or other pipes and fittings changing hoses that look perfectly good if they dont need to be replaced.
Is anyone running 14 Year old hoses?
I do an annual coolant flush and have never had black discoloration, chunks or anything else in my coolant. It always has and always does come out the same as it went in!
As always before, I appreciate any and all comments but most of all, advice.
Thanks FJR Owners!!
