Coolant leak after maintenance work

Postby wellman » Wed Apr 01, 2015 3:17 pm



Hello,
Somewhat baffled right now. Just finished lot of maintenance work on my 2000 1500 SE. Timing belts, cruise / sub filters, air filter,fork brace, shifter brace, shifter seal, Optic Armor windshield, etc. Started bike up and now there seems to be a coolant leak high on engine. I did spill a little coolant when filling but this does want to go away. Dripping on exhaust pipe on right side, seems to be high, above where side cover snaps on in area toward rear of engine. Likely following frame or hoses down.

Posted last week about a possible water pump seal. That turned out to be leaking around bolt/ copper washer.
Can't get back to it for a couple of days but can anyone think of something I may have loosened or overlooked while working on bike in that area? I plan on blowing it out tonight then letting dry while I am gone, may see better then.
By the way, could have never done most of that work without help from this forum. What a great group of guys to post all of this information and follow up answers as well.
Thanks in advance!

Not real familiar with your model. But when I have had leaks as you describe I have found a hose clamp or a single nut or bolt that I missed in the reassembly. Maybe just hand tight? Just food for thought. Good Luck!

Yup, could be one of the carb coolant lines, but yes, every time I've had a coolant leak like you describe, it's always been a weak original OEM "spring type" hose clamp. Replacing them with a quality screw-drive clamp has always fixed it for me.

Gentlemen,
After looking at again last night, I believe it was the radiator cap leaking. Used mirror and paper towels and it appeared to seeping. Cleaned everything really well, tightened cap, ran until fans were cycling and the leak has stopped- at least for now and there was no puddle in floor this morning. Plan on replacing cap this weekend and monitoring. Will also replace the clamps on the y-hose on front on engine.
Thanks for the advice on this issue.
CMR - Thank you for your service to our country, don't think we can say that enough.

WingAdmin - Another big kudos for the website. So much information here, better than any other sight I have seen for technical information.
