Coolant Leaking Bottom Water Pump

I got a 2013 ZX10r with alittle over 3k miles on her.


noticed when i did a oil change last week there was build up of dried coolant underneath on the water pump..

I cleaned it up and checked and added coolant to proper level as it was alittle below Low.

this week checked it again and it was back same place..

took some pictures. It almost looks like it is coming out of that little hole in the picture.

Maybe someone can shine some light on what it is? I am pretty handy and really don't trust the dealer to work on it if it is something i can do myself.

If it's coming out of that hole, then you likely have a bad impeller seal. The hole is there to drain the coolant out of the housing if the seal goes bad and before it gets into the oil. Drain the coolant, pull the pump, disassemble it, and replace the mechanical seal.

Okay.. Thanks for the info skydork!

I am looking up the parts and there appears to be a oil seal #92049-0778 and a water seal #49063-1055 do need to do both these or just the water seal #49063-1055?

Also when i take it apart there appears to be a O ring seal do i need replace this also and get this part also? #92055-0208

Anything thing else i should need besides coolant and the seal?

I would replace everything in there while you have it apart. Might as well since you'll have it out. Other than that, there's no special tools needed or anything. Shouldn't take too long either. Getting the mechanical seal it will be the hardest part. Just check the shaft to be sure there's no burrs or debris in there that will cut the new seal

I always believe the "Seep Hole" gets activated when the impeller bearings are starting to fail which will allow coolant to the hole because of the looseness if you will, to reach the Seep hole do to high pressure in the system..........Just FYI stuff this comes up from time to time. The reason I chimed in is because when you buy a used system say on ebay or something you never really know if it's good the Seals and everything else could look good but when things start to spin under pressure than you may have problems.

You know there's no separate bearing in there, right Bloo? The mechanical seal is the bearing. The shaft just rides in the seal and it acts as a plain bearing.

yeah i saw ur post.. i posted in there but no response so i thought i would start my own post..

What all parts did you replace while you in there? part #s? In manual it says special tool needed for bearings.. i saw u used a hammer thing? I can't believe with only 3kish miles things like this are failing.
