So I've got an 08 SM610 that seems to be leaking coolant. I did a valve adjustment about 500 miles ago so naturally I had to remove and refill the radiators. Things have been fine until last night when I noticed that there was coolant all over the right side of the cylinder head. I've looked all over the place and I can't find where it's coming from. At first it happened on a streak of hot days about a month ago so I thought it was some over heating issue. It went away for a month and then I notice it again this morning but it was cold out today. I can't seem to find any rhyme or reason to this thing! The right radiator is full and there is coolant in the reservoir... I'm clueless, any ideas?

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!
Mystery Coolant Leak

There should be green coolant residue from the source, look under the edges of the hose ends. Sometimes new hose clamps alone are not enough, have to reposition, maybe wipe down the fitting, slide the hose clamp to a new position, and/or make sure the clamp is square on the hose.
Any experience with this?

Sounds like a blown head gasket.

just asking, not at all sure, would a blown head gasket leak coolant on the outside?

If your oil is good I would clean the engine and other areas and then coat it with baby powder and see if you can pinpoint the leak.
As far as head gasket goes I would just assume that if there is water in the oil and rad fluid also leaking it would most likely come from a head gasket or base gasket.....But I could be wrong as it happens often

I would start with the easy stuff first just take the gas tank off, inspect the rads,hoses also if have a friend with a shop you can get the coolant system pressurized(leak down test) and look for external leak. Like Rockchucker22 said if you drain your oil and it is not milky you are fine.
