Quick question as far as a possible leak on my 2011 GT. She's at 74k miles and running well but last week I noticed some coolant on the floor and there was a few drops sitting on top of the water pump. I thought maybe the hose clamp was a little loose and snugged that down. Noticed it again and seemed to drip down from inside of the left fairing. I pulled the fairing and don't see any obvious source. I was wondering if there were any suspects that would be a source or is the water pump on its way out?

Otherwise the bike is running fine and is not overheating or anything like that.

You have to determine whether it's close to the water pump (which would be shot), or the radiator cap, or the overflow tank.
You said you saw water on the TOP of the water pump. If the pump were leaking the coolant would drop below the pump.


I would run the bike w/o the left fairing and try to source the leak. For instance you would be able to see whether the overflow tank is getting full when hot.

I had a 2000 Sprint ST through an unfortunate tip over in the driveway turned into a somewhat fortunate event as I discovered a coolant leak during disassembly of the fairings. It was difficult to figure out where the leak was so I let it run in the garage while I mowed. Turns out the coolant was leaking through the ends of the hose, through the webbing. Weird. Yours may not be doing this but something to look at as a possibility.

On the bottom side of the water pump there's a small hole. When coolant drips out there it's a sign that the shaft seal is leaking. Unfortunately, the pump isn't designed to allow seal replacement so it's usually a pump replacement. I replaced mine at 49K miles.

See this post

Like fredsprint, I'm a bit thrown by your report of drops of coolant sitting on top of the pump but still take a look with the engine running and see if you can spot any drips of coolant coming out of that hole.

I have been riding the bike to work about 38 miles each way, the last few days and when I get home I throw a towel down to catch anything and haven't seen anything. Given the mileage I am at and am almost due for an oil change I am leaning towards swapping out the pump anyway. I couldn't find any obvious source of a leak further up in the engine.

With a cold engine. An easy way to check if the water pump is leaking is to take a Q-tip liberally swabbed with Vaseline and push it into the water pump vent hole, to act as a plug. Leave it set overnight, remove it the next morning and coolant will flow if the pump is leaking.

I noticed the inside of the fairing was a little damp again and seems to be right where the weep hole is located. Ordered a new water pump and will hopefully get that doen with my oil change next week

When i first bought my 11 Sprint GT at just under 11K i noticed it had a slight coolant leak and the level in the recovery tank was low. It turns out that the clamp at the top of the coolant hose above the water pump was loose. Coolant was trickling down the back of the hose and resting on top of the water pump. Your bike has many more miles than mine did so it's entirely possible that your water pump has failed but it may be worth checking. I was relieved that it was that simple of a remedy to tighten the clamp. Hope you get it sorted out.

So I replaced the pump, and I think its bad. I rode it to work once, 78 miles round trip and noticed a stain on the driveway the next morning. Tried to ride in yesterday and made a pit stop and noted coolant pouring out. So today I got the fairing off and noted after running for a minute coolant is pouring out of the weep hole. It was installed as per the instructions in the shop manual and was a rather easy job. Is this that they sent me a bad pump or is there something else I am missing.

So this gets better and better. I call bike bandit to tell them they sent me a faulty pump and tell me I need to take the bike to a triumph dealer to have them look at it to guarantee its faulty then they will give me a new pump. First off I don't trust the closest triumph dealer, second its going to take I don't know how long for this to actualy get done and assume I will be on the hook paying the shop to do the work I can do my self.
