Refilling coolant
Coolant helps keep the combustion engine at the right operating temperature. The heat trans-ferred from the engine to the coolant can beused to warm the passenger compartment.
When refilling coolant, follow the instructions on the package. Never fill the cooling system withonly water. The risk of freezing is increased withtoo low or too high amounts of coolant. If there is coolant under the vehicle, smoke from the cooling system, or if more than 2 liters (about2 quarts) of coolant has been added to the sys-tem, there could be something wrong with thecooling system and starting the vehicle coulddamage the engine. Call a tow truck and do notattempt to start the engine.
WARNING
The coolant may be very hot. Never unscrew the cap when the coolant is hot. If coolantmust be filled, unscrew the expansion tankcap slowly to relieve overpressure.
Coolant expansion tank, left-hand drive vehicle.
