Does this radiator come with a thermostat or water pump?

No, this is the radiator core and tank assembly only. You'll need to source thermostat and water pump separately if replacement is needed.

What condition is this radiator in?

This is a factory replacement radiator in new or like-new condition, ready to bolt in without core repair or flushing.

Will this work with my existing hoses and clamps?

Test-fit before final installation — hose diameters and connection points should match factory spec, but condition and fitment of existing clamps should be verified before commitment.
