Changing Engine CoolantNJLC0079WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
Ð DRAINING ENGINE COOLANT ÐNJLC0079S011. Set air conditioning system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch ON and set temperature controller to maxi-
mum hot position.
b. Wait 10 seconds before turning ignition switch OFF.

2. Remove lower radiator hose, and remove radiator filler cap to
drain coolant.
3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
+Be careful not to allow coolant to contact drive belts.
4. Cover the exhaust tube heat shield to prevent from splashing
coolant.

Imp qt)/min or lower.
(Close the air relief plugs in order starting with the location from
where the coolant began spilling out.)
