1989 GL1500 Over Heating

Postby JPochron » Mon Feb 15, 2016 2:18 am



A few months ago I purchased a 1989 Honda GL1500 Trike with 110,000 miles on it. Since purchasing it I noticed the temperature gets almost to the red very quickly. At highway speeds it fluctuates from 1/4" to just touching the line before the Red Mark. On city streets getting caught at a Red Light it will go over to the Red but drop as soon as speed picks up. It hasn't gotten to the point where it boils over and I checked the fans and they both work. Other than flushing the system not sure what else I can do other than possibly change the thermostat and check the fan switch. I haven't driven very far with it and I keep a close watch on the gauge to ensure it doesn't get into the Red and stay there. Any suggestions would be greatly appreciated

If water level is correct I would suspect the thermostat is stuck open, if closed it will boil over.

If it was stuck open all the time wouldn't that allow the water to cool faster rather than waiting for it to get to temperature and then allowing it to flow. I would think if it stuck in the open position it would be running cooler

Sounds low on water, check when cold by removing radiator cap (not reserve tank). Fans should come on at about the 3/4 gauge mark and turn off at about 1/2 way mark of gauge.
This is what I do
Local and need repair help with your 1500, Valkyrie or ST please PM

Sorry, internet went out for a while, freezing rain here.
If stat is closed it will get hot and boil over. Is water level is OK ? Stuck open is not always wide open and will let temp go up but moving air will let temp drop. If it can't close the temp will go up every time you stop.
