It seems that every GL1800 that comes into my shop has cooling hose leaks ... nothing new there. Lately, ones coming in with around 100,000 always leak over night when the pressure tester is left on and from the large rad. hose clamp at the LF rad connection. Nothing unusual there either. Here is the confusing part. The one in my shop now, an 06 with about 100k on it, has had the eng pulled twice. So this is not an example of the OH worker not tightening a hose clamp. And why always the LF and never the RF. Both LF and RF hoses are well potected by an inner cover. Any body got any ideas why it is often the LF and not the RF? The only thing I can figure is from more exposier to oncoming traffic's wind blast.
