1996 Volvo 960
The risk for overheating is greatest, especially in hot weather, when:
●
towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
●
stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
To avoid overheating, the following rules should be followed:
●
Reduce speed and downshift when towing a trailer up long, steep inclines. The risk of overheating can
be reduced by switching off the air conditioning system for a short time.
●
Do not let the engine idle unnecessarily for prolonged periods.
●
Do not mount auxiliary lamps in front of the grill.
When the risk of overheating is imminent, or in the event of overheating, (the temperature gauge goes
repeatedly into, or stays continually in, the red section) the following precautions should be taken:
●
Switch off the air conditioning system.
●
Stop the car and put the gear lever into neutral. Do not stop the engine!
●
Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice
idling speed) until the temperature begins to drop.
See "Coolant" to check and top-up the coolant level if necessary.
WARNING! Do not remove the coolant expansion tank
cap.
WARNING! Do not drive with trunk lid or tailgate open!
Poisonous exhaust gases may enter via the trunk lid or tailgate.
If the trunk lid/tailgate must be kept open for any reason, proceed as follows:
●
Close the windows.
●
Set the ventilation system control to and blower control to its highest
setting.
Driving through standing water
CAUTION: Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.).
Damage to engine could result if excess water is ingested through the air intake system. Never drive the
vehicle in water deeper than 1 foot (300 mm). See the flood warning on
page 3:7 .
