How much does it cost to replace a water pump in Denver, CO?

Water pump replacement in Denver, CO typically costs $400–$900 as a US independent-shop average. Labor varies with pump drive type — serpentine-belt-driven pumps take less labor than timing-belt-driven ones — so the range is carried whole, never averaged to a point. A green puddle under the car usually points here — it is coolant from the cooling system, not transmission fluid.

Likely causes

• Leaking seals — The first sign is usually coolant loss or a puddle, not noise.
• Bearing wear — Whining or play at the pump pulley.

What you can check yourself

• Check coolant level and look for pink/green residue near the pump before driving far.
• A green puddle under the car is usually coolant from the cooling system, not transmission fluid — check the coolant level and have the leak found before driving far.
• Ask whether the quote includes coolant, thermostat, and hoses or prices them separately.
• Overheating with a leaking pump means stop — driving on overheats the engine fast.
