Re: ford focus 2003
Hi hypajunior, Check your coolant level ensure you have power to the fan (I am assuming it is an electric fan) if you have power to the fan you may want to check your thermostat or the coolant temp sensor,it will be a thread in fitting with a plug attached to it hope this helps good luck to you

You need to idle the car for a while to get it started to heat up to switch on the fan. the thermocouple must sense the heat to switch on the fan. If not the relay and the fan must be checked individually with an external supply to confirm if the auto sensor is faulty. Also check for the fan fuse if there is no supply to the relay. Finally the speedometer is faulty and needs to be replaced unless it is struck on the high side which can be confirmed ONLY if you remove the panel and tap it to come to rest.
Cars usually overheat when the thermostat is faulty, coolant level is low, or the water pump fails. If your cooling fan on the radiator does not kick on shortly after the engine reaches operating temperature, you may have a bad cooling fan, cooling fan relay, or cooling fan fuse. If your engine is overheating, start by checking the fluid level, and installing a new thermostat.
Never hot wire a cooling fan on a computer run car. Check the relays fuses and resistor connector in between the two fans. They usually melt the connector. I fixed mine with two female spade connectors
1. Does the cooling fan turn on when it over heats? 2. Check your coolant level, if it is a little low it will cool normally under transit and over heat in the conditions you are describing. Also have your coolant check for proper dilution. 3. If your cooling fan is failing to turn on you may have a coolant temperature switch issue.
