Engine Maintenance 9-7
SL, SLX, SLXe, SLXi Spectrum MODEL NOTE: The expansion tank vent tube vents air from the expansion tank to the top
of the radiator inlet tube while the cooling system is being filled. If the vent tube becomes bent, coolant can be trapped in a
low spot in the tube. This coolant can trap air in the expansion tank and make the cooling system appear to be full when it is
not. The unit will overheat if the cooling system is not full. Make sure that there are no low spots in the expansion tank vent
tube between the expansion tank and the radiator inlet tube.
