Chrysler 1997 Stratus Convertible LHD, Service Manual, Page: 205 / 1196

WARNING: DO NOT REMOVE THE COOLING SYS-
TEM PRESSURE CAP OR OPEN THE RADIATOR
DRAINCOCK, WHEN SYSTEM IS HOT AND UNDER
PRESSURE
BECAUSE SERIOUS BURNS FROM
COOLANT CAN OCCUR.
To drain cooling system move temperature selector
for heater to full heat with engine running (to pro-
vide vacuum for actuation). Without removing
radiator pressure cap and with system not
under pressure, Shut engine off and open draincock
(Fig. 21). The coolant reserve tank should empty
first, then remove radiator pressure cap. (if not, see
Testing Cooling System for leaks).
NOTE: To open draincock on vehicle equipped with
2.5L engine, use a 3/8 inch drive extension 3” long,
a 19mm socket with universal.
REFILLING COOLING SYSTEM
First clean system to remove old glycol, see Cooling
System Cleaning.
Fill system using antifreeze described in Coolant
section. Fill 50 percent of capacity with 100 percent
glycol. Then complete filling system with water. The
thermostats in the these engines allow air flow to
through them.
Continue filling system until full, this provides bet-
ter heater performance. Be careful not to spill
coolant on drive belts or the generator.
Fill coolant reserve system to at least the FULL
HOT mark with 50/50 solution. It may be necessary
to add coolant to the reserve tank to maintain cool-
ant level between the FULL HOT and ADD mark
after three or four warm-up, cool down cycles and
trapped air has been removed.

improperly located O-ring may cause damage to the
O-ring and cause a coolant leak.
(2) Assemble pump body to block and tighten
screws to 12 N·m (105 in. lbs.) (Fig. 22). Pressurize
