== == Cooling fans are designed to start at 235 degrees
Thermostat is stuck.. Is the cooling fans coming on at 232 degrees? Is the radiator sludged up?
Need to know what to hot is. A typical cooling system will run at 200 degrees F (+ or - 5 degrees). This is normal.
Test the temperature at the radiator--cooling fan is designed to come on when temperature is 235 degrees
Is cooling fan working? Radiator clogged? Air flow through radiator resrticted? Temp gauge accurate - check with manual?
Check the temperature at the radiator when hot Cooling fan is designed to come on only when:A/C Compressor is on (either during cooling or defrosting) orwhen coolant temperature exceeds 235 degrees Fahrenheit
Water in a car radiator does not normally boil. In some old cars, the cooling systems would run at about 220 degrees Fahrenheit. The pressure would be high enough so that the water would boil at 250 degrees. Today, you do not put water in radiators but coolant. It is much more efficient than water for cooling engines.
Electric cooling fan? Fan placed behind radiator to aid in engine cooling activated when engine coolant temperature exceeds 235 degrees F or when A/C or defroster is engaged
The engine temperature must reach 232-235 degrees in order for the cooling fans to come on. They will shut off at about 195-200 degrees. Also when the air conditioner is on the cooling fans automatically come on regardless of temperature.
An pressurized automotive cooling system containing a 50/50 coolant/water mixture will boil at 236 degrees F.
Most cooling fans come on low speed around 150 to 180 degrees Fahrenheit. Unless, your running the air conditioner or the defroster. Turning on your air will also activate the cooling fan.
The radiator alone, about 4 qts. The complete cooling system, about 12 qts. A mixture of 50% water and 50% antifreeze should protect the engine to minus 34 degrees F.
Run the vehicle with the radiator cap off, adding fluid as nessesary. also a product available from Advance Auto Parts is Water Wetter. it helps to lubricate and cool your engine.
