Where is the thermostat on a 1986 Honda V65 Magna?

There are 2 coolant hoses on the radiator...one that is on the bottom corner of the radiator on the left side of the bike and one that is on the top corner of the radiator on the right side of the bike. Follow the upper hose on the right and it goes underneath a 4" X 6" chrome side cover aka the Air Intake Cover Left. Remove the two bolts that attach the cover and you will find the thermostat housing...which coincidentally houses the thermostat. Remove the two bolts that hold on the top of the housing to access the thermostat. Here is a link to a parts microfiche that has all the details: http://www.cmsnl.com/Honda-vf1100c-v65-magna-1983-us_model1119/partslist/E++16.html Note: Whether or not you replace the thermostat, once the housing cover has been loosened and/or removed, you will still need to replace the o-ring between the upper and lower sections of the thermostat housing. Honda P/N's for the thermostat and the o-ring are #19300-MB0-003 and 91307-MB0-003 and they will run you about $45-$60. Alternatives for the thermostat and o-ring are advertised on Ebay (keyWord search string is "Thermostat Kit VF V30 V45 V65 Magna Sabre Interceptor") for under $20 including shipping. I am providing this info for reference only - No warranty or guarantee as to form, fit or function is either stated or implied. Caution: If you are having problems with your cooling system (engine running too cool or too hot or overheating or boiling over), there are several things you should consider doing before going to the expense and effort of replacing the thermostat. There can be many causes of cooling system problems...some are primary and some contributing. They include, but are not limited to, stuck open or stuck closed thermostat, bad or malfunctioning coolant temperature sensor, excessive coolant system deposits or corrosion, obstructed or leaking cooling systems sections of the bike's frame, radiator, thermostat and/or coolant hoses, improper coolant to water ratio, weak or exhausted coolant, low coolant level, wrong spark plug heat range just to mention a few...you can google the SabMag links on the internet for specific information. It is best to get a Clymer's Motorcycle Manual and/or the Honda Service/Shop Manual and browse the Web for related motorcycle cooling system trouble shooting and/or repair postings before you consider any DIY repairs that you may or may not have the knowledge, experience or the aptitude to perform. Hope this has helped and remember to keep the rubber side down! Hot2MtnBike
