On extremely hot days, be sure to keep an eye on the temperature gauge. If you're running hot, make sure to shut off the air conditioner and roll down the windows. If this doesn't lower the temperature, turn on the heater to get coolant circulating through more of the engine.
If the temperature rises beyond the normal range, stop the vehicle as soon as possible. Continued operation of an overheated engine will cause serious damage, so pull over to a safe place and raise the hood. Be extremely careful of radiator and hoses which may be spraying steam and hot coolant. Never remove the radiator cap when the engine is hot.
If vehicle overheated because of a long hill or from sitting in traffic on a hot day, run the engine at a fast idle (approximately 1,500 rpms) until temperature returns to normal.
If there's coolant leak, broken belt or other malfunction, shut off the engine. After the engine cools, check coolant reservoir while engine is running and bring the vehicle to a Nissan dealer. |
