how hard is it to change a heater matrix? <p></p><i></i>

[gerrsvolvo]

Not very hard.<br>About 2-3 hours work in total for replacing the matrix.<br><br>See the Haynesmanual.<br>You have to<br>1- empty the coolingsystem (if you are clever only<br> partly)<br>2- disconnect the heaterhoses under the bonnet<br>3- remove the complete console by the handbrake to<br> the dashboard.<br>4- remove the side carpets under the dashboard.<br>5- remove the two plastic-hoses between the heater<br> and the floor<br>6- remove the screws (4 or 6) on the left- and rightside<br> of the heatercase<br>7- now you can retract the heatermatrix (be carefull <br> with the tubes form the heatermatrix by some types<br> you have to disconnect these<br>8- placing the new matrix might be a bit fiddeling<br><br>rest vice versa<br>Good luck and warm feet.<br>I did it in two hours.<br>But I had some training by dismanteling the heatermatrix I needed from a car in a scrapyard.<br>Gerrsvolvo <br> <br><br> <p></p><i></i>

<br>the heatermatrix is a small radiator that is integrated in the coolingsystem.<br>In the 480 (and all 400 types (as far as I know) the heating system has no heatervalve that controles the waterflow trough the heatermatrix.<br>The temperature foor the inside of the car is regulated by mixing cold and hotair.<br>Because of this the heatersystem-air does not smell as bad as with systems that use the watervalve system.<br>The drawback is that especially in the summer in the 480 you cannot use the heatersytem as extra coolingcapacity for the engine if needed. <br>save kilometers<br>Gerrsvolvo <p></p><i></i>
