Product Overview
Bobcat describes 6684865 as the water pump for V2003TMDI Tier II engines. It circulates coolant through the engine, hoses and radiator; Bobcat specifically notes that coolant leaking from the pump's lower weep hole is a warning that pump failure is approaching.
Official fitment is narrower and more precise than the old title. Bobcat lists S160, S185 and S205 skid steers; T180 and T190 compact-track loaders; 341, 435, E50, E55, E50Z and E55Z excavators; and 5600/5610 Toolcats.

Before You Order

Frequently Asked Questions
Does the gasket come with 6684865?
Bobcat states that gasket 6684870 must be ordered separately.
What does leakage from the weep hole mean?
Bobcat notes that fluid leaking from the bottom weep hole typically indicates impending pump failure.
Why were some models removed from the old title?
The manufacturer fitment data for 6684865 does not list them, so this description uses the stronger Bobcat application information instead.
