gaskets (P/N GP-18899). See Figures 6-3 and 6-4.
13. Disconnect the exhaust temperature sensor (Figure 6-3) by unscrewing it from the exhaust
manifold.
14. While supporting the exhaust manifold, remove the two (2) side nuts (Figure 6-5) securing the
manifold to the heat exchanger. Loosen, but do not remove the third nut nearest to the front
of the unit.
15. Remove the exhaust manifold from the unit.
