GL1800 Overheating

Postby cmwagner » Mon Apr 06, 2015 12:40 pm



Hi all you Goldwing Addicts

So our SAGA continues. The overheating is still not solved, we have tried everything that everyone has advised - Thanks to All

We have found that placing the cooling system under 1.0BAR of Pressure (thru a home made cap), and in Idle Mode, we waited for the Fans to kick in, the minute they kicked in the Pressure would drop immediately and the Temp would start climbing.

When we turned the Power Plant Off, and checked the Water Level in the Radiator it was GONE, dropped drastically, in seconds, so we filled it up again applied pressure again started the engine, waited for the Fans to Kick in, pressure dropped again, switched off and checked water had dropped again (Gone) we added water again, started it under pressure, once 1.0 bar was reached, switched off (prior to fans kicking in) checked water - 100% - still full

Checked under bike - nothing, checked Oil - fine - NO Water leaking

Don't know where it is going and from where

Any Help would be appreciated, as short of Burning it now, we are clueless

Thanks in advance

From just a WAG (Wild Ass Guess), is there steam coming out of the exhausts? The water must be going somewhere, and if it is not the oil, then it must be somewhere if not going out as steam. Sometimes when you fill the overflow tank, the radiator beneath it is not quite full. Have you removed the radiator cap to inspect inside the actual radiator, and filled that up, then fill the overflow tank to the marked level - do not overfill.

The world is not going to finish today, as it is already tomorrow in Australia and New Zealand, and other islands of foreign nations such as Guam and Samoa.

ditto as above.

They might take a while to suck in the correct level of water after a few cycles.

BUT it must be going somewhere..

Hi Colin

Have you done a pressure test and a combustion leak test?
Any radiator shop should be able to do it for you.

Regards
Rob

Thanks to all that answered me and gave me suggestions.

After months of battling to find out what the issue is, the problem we have found with the Wing is a Blown Left Hand Side Head Gasket, Man and this is now a Problem, cause not even HONDA South Africa knows how to replace this.

PLEASE can anyone advise me where I can get Literature/Videos or Reading Material on how to do this. Bearing in mind I am NOT a Mechanic - however I have stripped smaller 400CC DOHC Motors before, so REALLY Hoping that the Wing is not to difficult, but I think that is Hopeful Thinking.

Thanks again Guys, you wont believe How much Help you all have been to us Poor Soles here in South Africa

Cheers

Colin
