Cooling advise

Postby tulsadutch » Mon Aug 13, 2012 12:09 pm



My 82 goldwing Interstate is having cooling problems, when I'm riding the Temp guage starts rising, it almost enters the Hot range but not quite. The radiator fan is operating but the guage never goes goes back down much. There is no liquid being lost out of the pipes nor is it showing up in the Oil or leaking on the ground. What could be causing the overheating problem and what should I do?

Thanks in advance

Is it full of coolant?
Is there anything stopping air flow?
If not I would remove the therostat and test it, most likely bad. might as well replace it since you are in there.

As mentioned the first thing to check is the coolant level. Have you recently replaced the coolant?

Son had a similar problem on Honda car. Turned out to be a head gasket just leaking enough for the coolant to burn off rather than show up anywhere.

I have to wonder if the thermostat isn't working proper, what do you guys think? Are all the other gauges working proper?

does sound like possible thermostat sticking and not opening up completely. I would looking into replacing it.

I am thinking the cause might be the thermostat, from what I'm reading I have to pull the radiator to get to the thermostat, is that correct?

Yeh, roll up your sleeves man, I'm pretty sure the radiator has gotta come out in order to get to everything there...I always forget the hose coming from the filler container...And sometimes I'll forget to unplug the fan unit :shock: ...word of advise, put all the bolts and washer and nuts in a safe place...And take a good look at the little bracket that the lower fairing mounts to...My first time I, forgot where the heck those silly thing went or how they went on.. :shock: :shock: I was like....duh :shock:

If your cell phone has a camera, I've found it helps a lot to take a few pics as your go through each step, then there is no doubt where everything goes when its time to put it all back together

If your fuel gauge is also rising and showing much more fuel than you actually have, the problem could be your 7 volt regulator.

To be sure, I would use an infrared thermometer to measure the actual temperature of the engine/radiator to determine if it's in fact getting overly hot, or if the gauge is just saying that it is.

also check that your cooling fins on radiator are clean and allows air flow.there is so much road debri and bugs up here in northern mn.it will plug off my air flow thru radiator in one summer.so i run window screen over radiator.lots easier to hose that off than radiator

I don't have a reply, actually a question of my own, not sure if I should be posting a new thread or not but have a similar problem. My 83 Interstate started running hot, needle at the middle of the white line. I had changed out the anti freeze, 3 flushes with distilled water, didn't notice any oil or anything in the old antifreeze. Still running hot so I thought I would replace the thermostat. You don't need to pull the radiator to do that, thought I saw that question somewhere.

There was no thermostat in behind the cover so that can't be it! The water pump shows no antifreeze at the weep hole. There was a bit of oil on the bottom of the water pump, I wiped it. No oil has reappeared after a 100 mile ride, but the bike ran hot, at traffic lights the temp did climb and was slow to go back down.

I pulled the radiator and hoses. They look old, the rubber rubs off very black on the fingers, but otherwise look ok. The inside of the rad looks clean from what I can see.

There is a tiny bit of play in the water pump impellor, the impellor blades look like a reddish plastic material so I read on here somewhere the pump must be OEM with the bike.

Could the issue be the water pump even though it shows no sign of leaking? I've had the bikes 2 years, did a 5700 mile round trip road trip last summer no problems till just recently.

I am curious , how did you get to the thermostat without pulling the radiator? It must have been a real tough thing with the fan in the way?

You're engine is not overheating until it gets up into the red zone, above 3/4 of the way on the gauge is where you need to be concerned.. 1/2 is fine..

Scott,

I was incorrect on not having to take the rad off for the thermostat, I had the water pump cap off too, and was having a brain *art about which I had taken off when. I do have the rad off and am going to get it cleaned, hope that will help.

did you install a thermostat to replace the one that was missing.some engines will overheat without a thermostat(not sure about an 1100)because the water circulates to fast for the radiator to remove heat.the thermostat slows water flow.
