Coolant Hose Replacement

[thfrider]

Getting ready to change coolant hoses on my 98 Tourer and just want to make sure I get them all.  I'm showing an upper and lower radiator hose, the radiator tube going to the reservoir, and water inlet hose (T shaped).  Is that all the rubber coolant hoses?  Also, should I change the T'stat at this time?

Sounds like a plan.

As I see it...the rubber hoses associated with your coolant system are as follows:

From this page:  http://www.ronayers.com/oemparts/a/hon/506cb675f870023420a41858/radiator

The rubber hoses are
Item 17 - Lower Radiator Hose
Item 18 - Upper Radiator Hose
Item 38 - Radiator to Reserve Tank Hose
Item 1 - Reserve Tank Overflow Hose (This one doesn't have to be anything special...Honda lists it as Bulk Vacuum Hose)

And from this page:  http://www.ronayers.com/oemparts/a/hon/506cb66af870023420a41832/water-pipe-thermostat

The rubber Hoses are
Item 5 - Right Water Outlet Pipe
Item 6 - Left Water Outlet Pipe

And from this page:  http://www.ronayers.com/oemparts/a/hon/506cb666f870023420a41824/water-pump

The rubber hose is
Item 5 - Water Inlet Hose

My only question is...why are you replacing all of your hoses?  I have replaced my upper and lower radiator hoses but haven't even thought about replacing the others.  Are you experiencing a leak anywhere?  Have really old coolant in your bike?  Fear corrosion/build-up?  Have overheating issues?

If you are going that far into this, go ahead and pull the thermostat and put it in a pan of water on the stove.  Place a thermometer in the water and heat it up.  Check the temperature where the thermostat opens.  I believe the thermostat is set to open between 160 and 190F.  If your thermostat doesn't operate correctly...check your local parts store for a "generic" part.  See this page for information:  http://www.jkozloski.com/generic_parts.htm

Hope this helps.

why?
are they leaking? showing deterioration?
Honda uses a much better material than USA oems.
under hood heat in a vehicle ages things sooner,
my '01 F250 113k miles still has the org hoses, no problems.
rarely do u ever hear of GL1500 goldwings changing them out.
the engine is not exposed to under hood heat.

No problem with the system, just a little leary of 17 year old rubber hoses.

After 149K and 17 yrs, I still have all the original coolant hoses. When I check them, they still feel soft and supple. No need to change them.

I replaced the hoses on my 97 just because of the years. The OEM hoses were just fine, I replaced them anyway and kept the old hoses. I did replace the thermostat with an automotive one from Auto Zone. It is working just fine. There is a note in the shop manual about the location of the small bypass hole.  FYI, the stat from AZ is under $10. The part is a Duralast #15868. By the way the OEM stat is $29.74 Your call?
