Anti freeze leak

[Barry.B]

Hi Guys I have a 2004 midnight Venture and as I was working on it today I notice a anti freeze leak on the left side front block behind where the fins are bolted on, it is a rubber plug that goes into block that looked like it should have a bolt in it but it don't . there is one of the same on right side to but not leaking . Has anyone seen this before ,your advice is much appreciated . and I also notice that my carb's on left side are all wet .

It's not uncommon at all. You can screw an old sparkplug into that hole and use it to pull the plug out. The new one just presses in and the fins keep pressure on them. A lot of people have taped a dime onto the fin just over where the plug is and it puts enough extra pressure on it to stop the leak.

Thank you Don for your advice I needed to change my antifreeze any way .

I did a temp fix on one on the left rear jug the other night. Don, how many of these plugs are there around the motor? I know I could look it up, but it's been a loooong day and I'm too tired.

I'm fairly center that there are just four. One under each Fin.

There are 4, one under each set of fins.

If you do not drain the coolant before you pull one of those plugs, you will have a minor flood on your hands. Never run the bike with the fins off, those plugs will blow out.

 

There is a very good write up in the tech sction on changing the coolant, with a very clever idea using an old water bottle as a funnel. It works really well.

That's what I was kinda figuring/hoping. Thanks!! Gonna add that to the list of to-do's. BTW, I did get my air cleaner project finished, but the weathers been too crappy to get it out. Maybe Sunday, sposed to be around 45 or so. I can tell that the throttle response is quicker now.

Does anyone have a pic of this plug? I have discovered a small leak myself on the left side under the rear cylinder. Is this the plug popping out?

 

[Skid]

What is the best way to go, replace the plug or place a dime over it?

[bongobobny]

Personal preference!!

 

I'm replacing mine...

[Skid]

I took the bike out for a ride and it has stopped leaking for now.

Anyone have instruction on how to replace it?

Drain the coolant, screw the top of a spark plug into the plug, pop it out and pop in the new one.

[Skid]

Sounds easy enough, Where is the best place to find a replacement plug?

[Gray Ghost]

I have looked at all the parts fiche I can access. Either the cylinder drain plug is mislabeled or they left it off the diagrams. You may have to check with a dealer because if they can't find it on the fiche either they can at least get the dealer help line to figure it out.

[Skid]

Is this the right plug?

[M61A1MECH]

Yes that is the correct plug, they are found on the parts diagram for the crankcase, the drawing I am looking at it is item 9 on the 2011 diagram, I suspect the diagrams for all years would be similar.

This thread could not have popped up at a better time! Mine just started leaking over the winter and I happened to realize my subscription was about up so here I am and so is this thread. Life is GREAT!

I put a dab of silicone sealer on mine and was quick to pull the old one and put the new one in. I lost very little coolant, and this worked good for me. The dealer did have to order the new plugs and a I think I used a penny ( I'm cheap) for a spacer til the new plugs arrived.

There is a small leak on the front right of my RSV again which was supposed to have been fixed by a mechanic a couple of springs ago. I'm going to try the penny fix. Does anyone know the torque numbers for the bolts holding the fin on?

Thanks
