How to Replace the Water Pump on a 95 Volvo 850

The Volvo 850 is a compact executive car made from 1992 to 1997 by Volvo Cars. It was available in sedan and station wagon body styles with front-wheel drive. The 1995 Volvo 850 had a 5-cylinder, 2.3-liter engine, or a 5-cylinder, 2.4-liter engine. Both engines have the same procedure for replacing the water pump. This procedure requires you to relieve the fuel pressure and drain the cooling system.

Instructions

1

Remove the fuel pump under the dashboard and start the engine. Allow the engine to idle until it stalls to relieve the pressure in the fuel system. Turn the ignition off and replace the fuel pump relay. Wait for the engine to completely cool.

2

Remove the cable to the negative battery terminal with a socket wrench to prevent the battery from causing sparks. Raise the vehicle with a jack and support it on jack stands. Disconnect the splash guard below the engine with a socket wrench.

3

Turn the heater control to the maximum setting and remove the cap on the expansion coolant tank. Place a drain pan under the radiator drain cock on the right side of the engine block. Connect a hose to the drain cock and place the free end of the hose in the drain pan. Open the drain cock to drain the coolant into the drain pan and close the drain cock.

4

Detach the fuel lines from the fuel tank and disconnect the expansion coolant tank with a socket wrench. Remove the front cover for the timing belt and the accessory drive belts. Disconnect the timing belt.

5

Disconnect the retaining bolts for the water pump with a socket wrench. Remove the water pump from the engine block and discard the old gasket. Clean the mounting surface on the cylinder block with a shop rag.

6

Install the new water pump and gasket to the engine block, and tighten the retaining bolts for the water pump to 15 foot-pounds with a torque wrench.

7

Connect the timing belt, accessory drive belts and the front cover for the timing belt with a socket wrench. Install the expansion coolant tank and connect the fuel lines to the fuel tank. Connect the splash guard and lower the vehicle. Connect the cable to the negative battery terminal.

8

Fill the radiator with coolant and start the engine. Allow the engine to idle until it reaches its normal operating temperature, then turn the engine off. Top off the coolant to the correct level and check the cooling system for leaks.
