How to Replace the Flasher Relay on a 1993 Volvo 850
Replacing the flasher relay on your Volvo 850 can be done very quickly and requires no tools. The flasher relay routes the power from the turn signal switch to the turn signals, converting the flow of electricity from a solid stream of power to an alternating stream, which causes the lights to flash on and off. If the relay fails, you can replace it with a new one, available from any auto parts store or through your Volvo dealer.

Open the hood of your Volvo and locate the fuse box on the drivers side of the engine compartment up against the firewall. Open the plastic lid by releasing the locking tab on the drivers side of the box then swing the lid towards the passengers side.
2Locate the flasher relay on the drivers end of the box, grasp it by the sides and pull it straight out. Discard the old flasher and install a new one by pushing it straight into the fuse box where the old one came out.
3Close the lid, snapping the locking tab in place. Close the hood of the car and test the repair by turning the ignition on and activating the turn signals, one side at a time.

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.
2Remove 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.
3Turn 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.
4Detach 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.
5Disconnect 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.
6Install 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.
7Connect 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.
8Fill 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.
