OVERHEATING on my 1988 GL1500

Postby thebrosman » Wed Jul 29, 2009 9:06 pm



I have an 88 GL1500. Over the last 2 weeks she has been gradually running hotter and hotter. I thought it was because the weather here in Southern California has been in the high 80's to high 90's. Typical summer in the desert. My reserve coolant tank has been/is, full. It has not been boiling or even bubbling during my "overheating". The temp does fluctuate while riding. It gets to the redline, stays there for what seems like forever, then goes down to 3/4 hot, then back up to redline. this is while doing 70 to 80 mph on the freeway. I think I have a thermostat problem. I have looked at the schematics and see that the the thermostat is NOT part of the waterpump housing assembly, like on a car. It has its own housing. It's just that I can't tell WHERE it is located. I have pulled off the lower and side fairings exposing the radiators and the water pump assy. I went down to Honda and the IDIOTS there listened to me explain my problem, then said they really don't know what the problem could be AND don't really know where the thermostat housing is actually located AND that if I would like, they would be happy to have someone look at it for $80 per hour. I have tried signing up for the "ask a mechanic" link from this website and was disappointed when the site came back and asked me "HOW MUCH AM I WILLING TO PAY" to have some unknown mechanic give me his opinion. If I had an extra 30 bucks I would buy the repair manual and fix it on my own. I am hoping someone out there has some help for me, who is willing to help without requiring payment. Anyone out there? Thank You for your time. Rudy

Hi There
I have got a CLYMER handbook and it seems that you have to remove the coolers and the fans to get to it I could e-mail you the pages from it

My 1992 is doing the same thing. Did you ever figure out the problem and a fix for it?
