Coolant smell and Oil in Coolant Overflow

Hey everyone....

About a month ago I rode the bike for a bit. As I was finishing up my ride, I noticed that sweet smell of coolant. Today on a ride, I did notice the temp creeping up higher then it normally would. Before I got too far out into the country I turned around, got some 50/50 and decided to top off the over-flow tank. When I did, I noticed oil all over the end of my funnel.... NOT GOOD. At time of this post haven't checked oil for foam or signs of coolant, that's next....

This is a 1983 GL1100 i with about 25-40K on the engine. If anyone could give me some tips on troubleshooting and to find cause and repair I'd appreciate it. I've parked it until I get this done. No sense making it worse. WINGADMIN, you've always been helpful, if you could offer up some help as well.

Thanks,
Ray

Could be head gasket-overheating/oil in coolant are classic signs.Nice DIY article on this sight, Regards, Johnyy

Hi bigray,

I would check three things:

- Check the water pump weep hole and see if anything is leaking out from it
- Drain the oil and see if there is coolant in it
- Pull all four spark plugs and see if any one of them is bright, shiny "steam cleaned" looking

A shiny clean spark plug is a sure bet that you've got a blown head gasket. Likewise, a leaky weep hole is a sure bet you've got a bad water pump or water pump seal. In the absence of either, I'd go with the water pump.

Yes-That did seem "somewhat" odd. Regards, Johnyy

I pulled the fairing and tank, drained the coolant. Which was regular "green" 50/50, I didn't really notice a huge amount of oil. I drained the oil and saw zero sign of coolant. Plugs, well they are nice and dirty and not shiny. So its my belief that I've got worn out seals in the water pump. I'm going with a stock Honda seal kit. Some older gear heads warned me these aftermarket kits usually end up with some type of fitment issue. I'll pay the money for the satisfaction...... I'm having a my mechanic do a pressure test just to be sure and then I'll go from there.....

Thank you all...
