Heater Boxes - Left non Cal

These are your source of heat. Used heater boxes are fine, just as long as the tin of the heater box is somewhat tight around the exhaust pipe where it goes through the heater box. If you are getting exhaust fumes, it's not normally the heater box; it's usually the clamp where the muffler joins the exhaust pipe coming out of the box. We highly recommend you flange this connection. Flanging the exhaust gets rid of the stock clamp and prevents leaks. The only drawback here is it is almost impossible to flange a stock muffler; therefore a header system is needed. Note: When you have the heater boxes installed and the cables hooked up, adjust the controls so that the heater is all the way on. Crawl back under your Bug and push on the control levers, making sure the boxes are open all the way. If they are not, readjust the barrel bolt on the cables so that they are opened. If you make sure all the connections where the heat travels from fan shroud all the way up to the body are air tight, the heater will work well. That is, as well as it can without water.
