Radiator volume

[wilmas2cool]

I did a search and didn't see anything. Does anyone know what the liquid volume of the radiator is for a 1984 Goldwing Interstate? I was trying to find out if I have a partial blockage that would cause it to run hotter than normal in warm / hot weather. Great site & smart folks.

If in doubt, remove the rad and take it to a rad shop, they can check it out.

Is your fan operating correctly? (check fan switch)

I know it's not what your after, After having heating problems I took mine to a rad shop, he said there were no problems with the rad. My problem turned out to be a bad head gasket.

i would have to agree with tricky, but alot depends on what u are calling warm or hot,and the situation which causes that condition
a warm day and running at 35 mph and a hot day running at 60 mph may create the same condition of "hot",plus since the interstae has a analog guage the sensor itself may be causing the high temp reading,whereas another sensor may report lower temp readings

in the summer above 85/90 even my asp or sei will occasionally run at least one bar hotter at times,my aspy usually runs two bars and my sei three,but alot of people report that normal for them is five or six bars,so what is normal for me may not be normal for you

first thing you should do is check the radiator at a shop,test the thermostat in a pan of water and go from there
i found out when i tried to replace my stock thermostat with an aftermarket one that the readings were higher on my aspy than the stock one and reinstalled stock and no problems since

Here's where I put in my two cents for changing water-cooled to waterless cooled GL1200 engines with Evans NPG+ Coolant

Evans NPG+ versus HONDA Genuine Long Life Antifreeze/Coolant, type 2
versus
[What a difference an extra carbon atom makes ]

Before getting my "new" Aspy, I rode an '85 Interstate for 3-4 years. My city gets REAL hot in summer and so I searched for somehow optimizing the GL1200s cooling system. Evans NPG+ waterless coolant was the answer. Relative to conventional ethylene glycol + water (aka commercial antifreeze ... which nowadays is 50% water) Evans NPG+ is waterless.

essentially 100% propylene glycol (much less toxic than old "antifreeze" ethylene glycol + water).

Pros: 1) Water boils at 275°F while Evans (propylene glycol) boils at 375°F ... 100°F higher than water. So what? That means while the GL1200 cooling system is performing normally, it is under zero additional positive pressure with water free Evans NPG+. 2) Moreover, the coefficient of heat transfer for propylene glycol (Evans) is 10-15% higher than for 1:1 ethylene glycol + water. So what? That means the GL1200 cooling system can dump heat faster with Evans NPG+ than with "antifreeze". 3) Water free Evans NPG+ is Noncorrosive. So what? That means the GL1200 cooling system's components will not get chewed up by the water + additives in "antifreeze".

Con: "OMG Evans NPG+ is expensive."
Oh, really ? HONDA Genuine Long Life Antifreeze/Coolant, type 2, 50/50 Prediluted which is half WATER sells for $27 per gallon. So what? That means you're paying about $27 per gallon for ethylene glycol but also $27 per gallon for water! WHAT ? Yep. $27 per gallon for water! With Evans NPG+ you pay about $40 per gallon for propylene glycol (which reputedly lasts 3-4 times longer than "antifreeze" 'cause there's no water in it).

Gee, could that be why private airplane operators and BMW and Mercedes auto shops ALL use Evans NPG+ and NOT 50% watery "antifreeze"?

End of NPG+ sermon.

Thanks Grandpah and you other guys for the info. This site is better than going to a Tech School at night.
I printed the troubleshooting steps from from this site and will start checking ASAP then check back with results.
