2005 Chevrolet Classic Water Pump Parts and Q&A

• Q: How to replace the water pump in a car with an automatic transmission on 2005 Chevrolet Classic?

  A: Replacement begins with Exhaust Manifold removal when the vehicle runs on automatic transmission. Start by emptying the cooling system and then securely raise the vehicle for work. Take out the right front tire first with its wheel. Afterward handle the front fender liner displacemnt. You need to remove the cover that gives access to the Water Pump sprocket on the Timing Cover. Set the Water Pump holding tool part j 43651 to the Water Pump sprocket and position it on the engine front cover through the access plate bolts. Unfasten Water Pump sprocket bolts to extract them and afterwards detach the engines block to Water Pump bolt followed by the engine front cover to Water Pump bolt. Before removing the Water Pump disconnect both its connections: the Water Pump to Thermostat Housing feed pipe and two engine block bolts. Thread the stud through the Water Pump sprocket hub and pump to line them up before installing the Water Pump. Secure the Water Pump against the engine block through the 2 bolts and fasten them to 20 nm (15 ft. Lbs.). Install the feed pipe first before bolting on the engine front cover using both bones and tightening them to 20 nm (15 ft. Lbs.). Place the last bolt into the Water Pump sprocket before taking off the threaded stud and bolt the sprocket to the Water Pump at 10 nm (89 inch lbs.). Put the Water Pump holding tool j 43651 aside then clamp the access plate onto the Water Pump sprocket to the Timing Cover and secure it with bolts which need tightening to 10 nm (18 inch lbs.). After that reinstall the front fender liner, right front tire and wheel together with the Exhaust Manifold when needed before adding cooling liquid.
