EWA13030
A hot radiator is under pressure. Therefore,
do not remove the radiator cap when the
engine is hot. Scalding hot fluid and steam
may be blown out, which could cause seri-
ous injury. When the engine has cooled,
open the radiator cap as follows:
Place a thick rag or a towel over the radia-
tor cap and slowly turn the radiator cap
counterclockwise toward the detent to
allow any residual pressure to escape.
When the hissing sound has stopped,
press down on the radiator cap and turn it
counterclockwise to remove.
The following procedure applies to all of the
coolant drain bolts and copper washers.
5. Remove:
• Coolant drain bolt (engine) “1”
(along with the copper washer)
6. Drain:
• Coolant
(from the engine and radiator)
7. Install:

washer )
8. Install:

mended coolant)
Handling notes for coolant
