Just Winging It
I can't buy a new radiator as it is discontinued. What do I need to do to fix one of these 2 radiators I have.
What's the difference between flow test and boiling out? What kind of flow is good?If it were just an indication problem, the cooling fans would cycle normally. You say they come on and stay on. If that's the case, then the thermo switch AND the gauge are faulty?
If it reads hot, and the fans stay on, then it is hot.
Take your stand-by radiator to a radiator shop and have it FLOW tested. Then install it.
Just want to get the right kind. I'd love to get 50,000 - 100,000 without cooling issues.Silicate free only, mixed 50/50 with distilled water.
The type of antifreeze you are probably has nothing to do with your current problem unless it turns out to be the water pump. Then, some silicates may have played a part.
Ok rode today stayed cool 10 miles added water to radiator after it cooled rode 20 miles home took the long way stayed cool maybe the new cap is helping. see if it keeps losing water.Rinsed out radiator put new cap on refilled idled fan cycled temp stayed good burped the air must test ride could have been the cap. Let ya'll know
GL1200I 1986There aren't many places to lose water besides the radiator cap or radiator itself. The head gasket(s), the coolant pipe joints, radiator hose fittings, water pump weep hole and most common, leaking in the line from the radiator to the expansion tank.
BTW - did you see any bubbles rising in the radiator neck when the engine was running? A leaking head gasket can increase the coolant temperature quite a bit.
Took it off it's a bit harder with the false tank on and it was leaking at the elbow connection I fixed it and put it back on. Thought I'd warm it up see what happens it smoked more I think then when I revved it to about 4 grand I could see a spray of water on the floor before the smoke went away after a few minutes. Then she seem ok could run a little smother though, I thought while watching her running.Take a good look at your expansion tubes and their connection to the expansion tank. It doesn't take much of an air leak there to prevent the coolant from being drawn back into the radiator as the engine cools. But that shouldn't cause coolant from being lost it will just impair the radiator's ability to function.
That's what I was thinking I'll pull the plugs and check, butPull your plugs after she cools inspect them. turn it over, with handel bar switch off turn it over see if water spits out plug hole.
I have a GL1200I mine has a needle gauge that does not exceed 1/4 now that I have replaced the head gaskets both sides with oem. (they were beginning to blow and there were pieces of the gasket in the coolant) Also the water pump was bad so I put a new one in. I think the bad water pump helped blow the head gaskets. The weep hole was plugged up.how many bars should show when cooling starts
I read your post and thought I'd go check the fluids in my bike just to be sure all is good. Well, the over flow was empty and radiator was low but I could see coolant in it. I refilled the coolant. Checked the oil and it has water in it. makes me want to cry. Guess I'll retorque to heads and pray couldn't hurt.Jeff,
So I take it that you are back on the road without problems? Good job!
The one thing you will hear from this site over and over…
1) Use OEM head gaskets!
2) Use OEM water pumps!
3) Use Randakk Carb Kits!
All of these will save you time and money. They might be a bit more expensive at first but if you don’t have to do the job again or sit and worry about your work then there is a big savings there.
Glad to see you back out on the roads.
