Draining Cooling System
1. Stop the engine and allow it to cool sufficiently.
2. Unhook the four retaining straps, and remove the
upper blower housing and screen assembly. See
Figures 8 and 9.
3. Check if the radiator is cool to the touch. Slowly
loosen the radiator cap to the first stop and allow
any pressure to bleed off. Then fully loosen and
remove it.

6. Remove the reservoir cap. Carefully tip the
bracket away from the reservoir, and lift the
reservoir out between the bracket and fan. See
Figures 14 and 15. Pour out the contents of the
reservoir and wash out or clean as required.
Dispose of all the old coolant properly, according
to local regulations.

4. Locate and remove the coolant drain plug in the
lower side of both cylinder heads. See Figure 12.
Drain the coolant into a suitable container. After
the coolant has drained, apply pipe sealant with
Teflon
®
(not Teflon
®
tape) to the threads and
reinstall the plugs. Torque the plugs to 13.5 N·m
(120 in. lb.).

5. The coolant overflow reservoir has 3 molded
protrusions (1 upper, 2 lower, see Figure 14) that
fit into corresponding holes in the support
brackets. Loosen the two screws that fasten the
upper bracket to the radiator. See Figure 13.
