Re: Cooling system issues 79 GL
I finally got the radiator back in today (sort of). I am having a very tough time trying to get to the upper radiator hose clamp.
I know there has got to be a trick if someone would be so kind as to share the trade secret with me.
I am REALLY hoping I don't have to remove the radiator just to put the top hose clamp on...

Re: Cooling system issues 79 GL
I install the top hose on the radiator before I install the radiator on the bike

Re: Cooling system issues 79 GL
If it helps, I also install the lower hose, and the water pump housing,....and install the housing when I install the radiator

+1. Hoses on the radiator, water pump housing in the lower hose, then install. Not much free play otherwise.CYBORG wrote:If it helps, I also install the lower hose, and the water pump housing,....and install the housing when I install the radiator

Re: Cooling system issues 79 GL
My motorcycle hates me. All the work I did to put a new water pump in and regasket everything and now that I have it running it is leaking oil out of the weep hole. a steady drip about two to three times a second.
I KNOW I did everything right as far as getting the proper o rings in the right places.
ALSO as if that wasn't enough the cooling fan will not run when the key is on. I have a bypass wire on the fan but that only works when the key is off??? When the key is on taking the bypass wire straight to the battery gets no results but if I turn the key off and go to the battery the fan will run???
I guess it doesn't really matter if I cannot get the oil leak stopped.

Re: Cooling system issues 79 GL
I put the oil in last week and it didn't leak a drop until I started it tonight.

Re: Cooling system issues 79 GL
There are only three possibilities for oil leaking from the weep hole; bad pump seals, buggered up o-ring on the pump, or one or more of the crush washers is not sealing. It sucks, but them's the facts. Order up another cover gasket and get 'er done...

Re: Cooling system issues 79 GL
I just drained the fluids and there was no cross contamination. Antifreeze was just antifreeze and oil was just oil. I will let it drip overnight and maybe tomorrow start tearing it back apart. I have my suspicions because when I put the water pump in the front housing it did not want to go in and I had to draw it up with the three bolts.
Where would be the best place to get a gasket set??? Thanks Dave

Re: Cooling system issues 79 GL
My other somewhat less obvious problem is the electric fan. It is weird that the hot wire will not work when the bike is running but if I shut the bike off then the hot wire works? The fan switch was checked and is good so it's got to be something else?

Re: Cooling system issues 79 GL
OK, I tore it back apart leaving the radiator intact and found a couple of things.
2. The O ring that I know I put where the water pump meets the oil pump has somehow mysteriously disappeared.
3. All the water pump bolts were tight and had the crush washers installed but I measured things and with the bolts tightly in the removed water pump it measured .276 " The thickness of the housing measured .292" That tells me that when the pump is in tight the o ring only compresses 16 thou.
By contrast the bolts tight in the factory water pump measured .225 that would compress 67 thou??? Much better
I am thinking that when they made the pump they skipped the step of running a plug tap in the holes to give it the maximum amount of threads.
So it seems to me that I could either try to find a plug tap (not likely) or shorten the bolts about 50 thou.
What importance does the O ring at the oil pump serve and would that cause the leaking issue?
Thanks Dave
1.There was some rubbing between the impeller and the housing which makes me think the pump was not seated fully.2. The O ring that I know I put where the water pump meets the oil pump has somehow mysteriously disappeared.

If you're just going to replace individual gaskets/o-rings as needed, Partzilla.com is fast and most of the time, cheapest for OEM.

Re: Cooling system issues 79 GL
I just ordered another gasket set but it probably wasn't needed as I was able to save the old gasket.
I checked the wiring for the fan and it seems to be right although when it was running yesterday it got pretty hot and the fan never kicked on. Today with the key on and a jumper wire at the switch wiring it came on. I will install a switch for emergencies but it should work now.
So far the plan is to shorten the bolts about 50 thou and regasket everything and try it again.
It is not too bad the second time with the radiator still there.
I just cant figure out why I had such a prominent drip.
