What are the costs to replace the water pump in a 2008 Highlander?

You can expect to pay between $550 to $750 to have the water pump replaced in a 2008 Toyota Highlander. The water pump alone will cost between $175 to $250, and the labor charges could be as much as $500. The most common symptom of a bad water pump is an overheating engine. A good indication of a failing water pump is the bearings in the pulley will begin to drag and cause a high pitch whining sound. You may notice coolant leaking at the front of the car or steam coming from the radiator. If the engine overheats it could cause the cylinders to swell, restricting the pistons which could break a connecting rod and destroy the engine.
