If your Yamaha Raptor 660 is leaking coolant from the water pump, this rebuild kit has the seals you need to fix it. It's compatible with model years 2001 through 2005 (Raptor 660 and 660R). The kit includes all the necessary seals and gaskets to refurbish your water pump, preventing leaks and keeping your engine cool. The part number is 11H-12438-10-00, which is the same as the OEM number, and it's made from alloy steel for durability. It's brand new, from MOTO1988, and comes in its original packaging. Installation requires some mechanical skill—you'll need to disassemble the water pump housing, replace the old seals, and reassemble everything. But if you're comfortable with ATV maintenance, this is a cost-effective way to avoid a bigger repair down the line. No UPC, and the warranty length isn't specified, but it's a genuine-style replacement part. Keep your Raptor running cool and leak-free. Perfect for DIY mechanics or riders who like to handle their own upkeep.
