The rear water pump does not pump water onto the windscreen I dont have the owners manual and dont know how to fill this rear tank up or if it runs thru from the front one

The front washers fill up near the left side step. the rear has its own resiviour and pump

Procedure to change the windshield washer tank or pump on an E46.

Tools needed: 10mm spanner (in toolkit), small-medium flat blade screwdriver

Undo the 10mm nut, highlighted in the red circle. This is the only fastener holding down the washer tank. Lift the tank up about 4", allowing you to unclip the black plastic heatshield around the washer pump. This is where you need the screwdriver, to lift the securing tab from the washer tank (yellow circle). You can actually pull out the complete washer pump from the tank. Just gently pull up, it is a friction fit.

Now unclip the washer level sensor plug (green circle). This clip is a little difficult to figure out. I pulled it hard and it came off. Taking a closer look at it once it was off, I couldn't quite see how to unclip it from its securing catch.

At this point you have removed the washer tank. The two tabs at the bottom of the tank fit into recesses in the body work, in order to secure the tank. There is a filter screen in the tank, where the washer pump plugs into the tank (blue circle). Just pry this up with a screwdriver to remove it. I had bought a new one, just in case. You can see the fluid level sensor socket on the left side of the tank in this pic.

Now unclip the pump connector from the pump. Pinch the tab at the top of the connector. This will unclip the connector from the securing tab. Pull out the water hose from the nozzle on the pump

Replace the pump filter screen into the tank, if necessary. Plug in the new washer pump into the filter screen. Connect the water hose back onto the pump.

Position the washer tank into its approximate location and clip the sensor for the fluid level back into its socket on the tank.

Secure the heatshield back onto the tank.

Now position the washer tank into its secured position and fill with a little water, in order to test the pump out. Fasten the 10mm screw back into the plug. Attached Thumbnails

Dont use water. Pressurized system requires coolant/water mixture to maintain proper boiling point. Coolant is added to coolant tank you have identified, there is no direct fill to the radiator, it fills out of the coolant tank.

On the Terrano's the washer pump that controls both the rear window and the headlight washers are fed from the same water reservoir found closest to the front of the vehicle. The one closest to the windscreen is for washing that windscreen but the larger one to the front washes both of the area's mentioned in your posting. On that unit there are two seperate pumps, one for the rear and one for the headlights. These have a tendancy to stop working through a variety of reasons. To check out the wiring a "Multimeter" is needed. Put the multimeter onto 12V if there is a setting for that on yours, if not put it onto 24V as most have that setting. Disconnect the wiring harness closest to the water reservoir and try each pin within the connection leading TO the reservoir. Attach one lead of your multimeter to an "Earth/Ground" point on your chassis and use the red lead to test each pin for voltage. If no voltage is found then try all of your fuses found near the drivers right knee area, but if voltage is found then try removing the pumps from the reservoir and purchase new ones that match. Usually a "Generic" model for the pump will be found to fit. I know I was able to find one when this same thing happened to me.

Hope this helps.

I would follow the mechanics recommedations. I think he's taliking about the cam and crankshaft seals. Yes the water pump should be replaced as well. The pump that sprays windshield washer fluid onto the windshield is called the windshield washer pump. The water pump is on the engine and pumps water (coolant/antifreeze) through the engine to the radiator and heater core.

This truck should have an 18 g tank. It is not likely to have been changed.

Hi

It is usually the fuse. This blows very easily.(eg Ifyou operaten the washers when the fluid is frozen or partially frozen)

Look in your handbook. And in the fuse box in the engine compartment

i presume you mean wiper water pump... first locate the relays for the horn and rear wiper and replace them... usually found in the fuse panel under the dash... then fill up the rear water resevoir for the back wiper and try it again.
