Overheating GL1500?!?

My (new to me) 1994 GL1500 runs cool on the road. In Florida in the summer, at a standstill, the temp needle swings to the right, but not in the red. Recently I got stuck on a dirt (mostly sand, some deep) road and had to "walk" it out at low speeds, feathering the clutch. It was mid-day in blazing Florida sun and hot, hot ,hot. The temp needle went to top of the white and even into the red.
Its due for a coolant change anyway, so I was wondering if I should refill with regular ethylene glycol (e.g. Prestone), or consider "Engine Ice"? Anyone else used Engine Ice? Is it worth the price? It does say its silicate and phosphate free....

Thanks!

can you hear the fans running?

Yep, as William said, check the fans because the engine shouldn't get much above the three quartermark if both of the fans are working and the cooling system is in good shape.

And for the antifreeze, just use Silicate Free. Not the old green stuff.

No need for fancy alternatives. I vote +2 on the fans not running.

For starters, even if the fans are good......running a 800 lb wing out in deep sand.......it's gonna get hot. No way around it. Few things are as hard on a bikeas walking it through deep sand while feathering the clutch. Use to drive me nuts before my kids could ride sand.......and they'd ring their little 80's out to 13 Grand while duck paddling in the sand..........right up until the radiators spewed. Of course, not all wing riders can get up on the pegs and ride sand.......so it's totally expected that a big bike like that might over heat. If you have to ride that road often..........you need to quit "walking" it.....get up on the pegs. Stand up, squeeze the bike with your thighs, and stay on the gas through the sand.



Malcom Smith ran sand at 90+ in Baja 40 years ago with less suspension travel and dang near as heavy a bike;-)



If that road was a one time thing.......don't sweat it. Check the fans/thermal switch for proper operation, and fill with good ol' Prestone High Mileage and be done with it.



And yeah........EI is good stuff.....but overkill for a Goldwing IMHO.

Thanks for all the info. I am no Malcolm Smith!!!!! Both fans were running, since I felt air coming out of the vents on each side of the wing. But I'm hearing a kind of squeeking or chirping that for the life of me sounds like an electric motor with bad bearings. I wonder of one of the fans if dying?!? THe right one felt strong, but the left one didn't feel as strong.

OK, I'll use the normal Prestone silicate-free stuff and flush it next week. It never boiled out the coolant, just the needle dipped into the red briefly.

Unfortunately, the sand was on the road to our second property. Never thought about bikes when we bought it. It would take a real off-road bike for me to even try it all the way. Not sure what to do about the property.....

Somebody must make knobbies to fit a GL15. :cooldevil:

I just got a gl1500 trike, and we were ride sunday here in ga. we stopped breifly after ride for a hour or so, with the engine running. the engine temp, rose but not into the red and starting leaking fluid and the fans did come on. Needless to say we started riding again to help air cool the engine. Does this mean the coolant need changing or a bigger problem. I have only had the trike a couple weeks, so don't have much history on the trike. What should I do??

First of all TN-Buggs...I would find out where the fluid was leaking from????...as it should not have leaked unless it was boiling in the radiators. Make sure it is not leaking from the bottom of the water pump weep hole. It would do this all the time if the pump was going bad...not just when hot. I would keep an eye on it for a while and if it was still doing it when hot then you might need to change the thermostat...(not a fun job).

To everyone who at one time has there temp gadge go into the redor just below the red with a 1500 try getting a new radiator cap you can get a stant or napa which is the on I went with 703-1406/stant is the 11233 when you lQQk at the 1500 cap youll sware the napa or stant wont work with the little ears on the sides but has just enough room to to fit just right !

+ 1 on what AZgl1500 wrote any honda shop will carry what you need !

You can get the Honda brand silicate free anti-freeze from a Honda car dealer cheaper than from a Honda motorcycle dealer. Same stuff. Only it's blue instead of green? Here
Somebody correct me if needed.:)
