Coolant Leak

Ive got an '08 KLR with 13000 miles. I just recently noticed coolant leaking and removed the skid plate to find it coming from the weep hole on the bottom of the water pump. I'm sure I'm not the only one to have this issue, whoever has had this problem if you could kindly let me know what I will need to replace and if you have an estimated cost for it all.
Thanks,
Josh

You will need to replace the seal and the o-ring. It's going to run you about $20 for the seal, o-ring and gasket. See here.

Your call on whether or not you replace the oil seal.

I recently done mine without too much trouble,
google klr650.marknet.us for good pictures on the procedure.
and a good tip on how to remove the old seals


Parts required

Mechnical water seal
Oil seal
Impeller o ring
Water pump gasket
Clutch cover gasket

As for cost $30-$40 should cover it

Tiptoes is right - I forgot the clutch cover gasket.

I appreciate the quick response. Is this a difficult project or is it fairly easy? How long should it take and are there any special tools I will need to complete this?
Thanks again,
Josh

Read the instructions well, the seal puller is the hardest part. If you have a well stocked tool chest you should be able to rig something up.

It took me about 3 hours but I also did a lot of cleaning and spent a lot of time cleaning the old gasket and seals away.

Very good pictures on the website, thanks. Though on that site it seems that they are doing it on an '07 or older are there any differences that I need to watch for? Or is it the same way to do it on an '08?

Also if all It is doing is leaking coolant out of the weep hole on the bottom of the water pump do I necessarily need to replace the oil seal and clutch cover if I only open the water pump and replace the impeller o ring, water pump gasket, and mechanical water seal?
Thanks,
Josh

Both seals are cheap, I did both. I'm not sure how you would go about only getting the mechanical seal out without removing the clutch cover, and if you open the clutch cover you should replace the gasket and sealant.

The mechanical seal isn't just setting in there to pull out, it is pressed in place and will take some considerable force to get it out, and to press the new one in.

It makes most sense to me and as the "easy" way to do it like the instructions state. If you do it your own way, post pics of how!!!
