ccterry Posted January 15, 2011 Share #1 Posted January 15, 2011 Coolant drain on the front of my '86 VR is dripping.To replace that o-ring you remove the little set screw in the side and then does that plastic plug unscrew or wiggle out of there.That fitting and the little hose on top were plugged up with a reddish brown clay when I flushed the system,now that I cleaned everything out it started leaking.Thanks Link to comment Share on other sites More sharing options...

In reality, this won't happen though, you will have to pull on it and wiggle back and forth. Next is a link to parts to fix it. If you want to drain coolant, the drain plug is on the right side of bike on bottom of water pump housing. http://www.venturerider.org/classifieds/showproduct.php?product=1724&title=first-gen1983-1993-radiator-drain-upgrade&cat=22 Gary Link to comment Share on other sites More sharing options...
Snaggletooth Posted January 15, 2011 Share #3 Posted January 15, 2011 Don't forget to wrap a rag around it while you are working it out of the housing. That way you don't have to spend any time looking for the ball bearing and spring detent. They have been known to hide in the oddest places. Clean out the inside of the valve housing it a piece of ScotchBrite pad to get the gung out. And Skydoc_17's lil kit it a good fix. Not a drop from mine since I installed it.

ccterry Posted January 15, 2011 Author Share #4 Posted January 15, 2011 Thanks. Now I understand how it's supposed to work. Link to comment Share on other sites More sharing options...
Snaggletooth Posted January 15, 2011 Share #5 Posted January 15, 2011 If ya got the "On" / "Off" setting figured out ya got it made. Once you get the valve cleaned up you will be able to feel the detent a lot better. These puppies are a common problem. Like the Off/On/Reserve setting on the fuel petcock they don't get moved a lot. Once you move them, they start that danged drip. Most folks don't notice it until cold weather sets in. When it's warm out and you ride a lot the o-ring holds pretty well. With the cold temps.....shrinkage. And on another issue.....Ok......you probably know the setting on the valve is "Off" at the 2 o'clock position for running the bike. The "On" position at 2 o'clock is for draining the system. The "On" setting bypasses the thermostat to allow full drainage. Now for that bit of info you are good to go. But in case of a problem down the road....like overheating because of a stuck shut thermostat.....just move the valve to the "On" position. That again, will bypass the thermo and let you get to a place to replace the thermo. It is a temporary fix, not for the long run. But it will get you to a safe place in a jam. A road side thermo replacement is not something I'd want to do. Tough enough in the garage. Mike Link to comment Share on other sites More sharing options...
ccterry Posted January 16, 2011 Author Share #6 Posted January 16, 2011 Thank you. I actually wasn't sure about the plug's positioning. The picture in the manual is a little vague. I just got the bike and was changing out all of the fluids.That valve was pretty gunked up which made it hard to tell exactly how is was supposed to work.I'll get that o-ring changed out this week too.

Trader Posted January 16, 2011 Share #8 Posted January 16, 2011 1st pic.....running position. 2nd pic....draining position the setting on the valve is "Off" at the 2 o'clock position for running the bike. The "On" position at 2 o'clock is for draining the system. Mike It looks like 2 identical pictures...and 2 identical descriptions (2 o'clock) for both ON and OFF....which is it????

dingy Posted January 16, 2011 Share #9 Posted January 16, 2011 1st pic.....running position. 2nd pic....draining position Good Lord Snag, what happened to that plug? Looks like it went skidding down the road at some point? Not one of those appearance items though, I'm just sayin Gary Link to comment Share on other sites More sharing options...
Snaggletooth Posted January 16, 2011 Share #10 Posted January 16, 2011 Hey Trader, Take a closer look at the pics. They are different. The valve falls into detent when turned to the proper 2 o'clock position. The "On" or "Off" have to be at 2 o'clock for it work properly. Hi Gary, Yeah, stuff ya buy in lots off fleaBay can be pretty rough some times. I clean up the usable stuff and stock it for "Just In Case". It's handy for pics to. LOL!

Must be time for new glasses....I couldn't see the difference until I expanded the pic. The thumbnail looked the same! Now I get it! Thanks!

Venturous Randy Posted January 16, 2011 Share #12 Posted January 16, 2011 I just tell people that in the run position, the top of the letters are toward the 5 oclock position. RandyA Link to comment Share on other sites More sharing options...
