OVERHEATING MY 2005 RANGER 2.3L WITH AN ELECTRIC FAN IS OVERHEATING WITH NO A/C. THE FAN DOES NOT COME ON WHEN THE GAUGES ARE PEGGED, BUT IF YOU TURN THE A/C ON, THE FAN COMES ON AND THE TEMPERATURE DROPS TO NORMAL. SO, NO FAN WHEN OVERHEATING AND COOLING SYSTEM IS IN GREAT SHAPE, PCM PROBLEM ??????

Sounds like your electric cooling fan is not turning on. Check the fuses and relays associated with the fan circuit.

The tiny electric motors that move the needles on the cluster are prone to failing. New sets of them are relartively cheap on E-Bay. Takes patience and some skill to change them.

sounds like a regulator malfunction to me..need to connect a battery/alternator tester to the system and see if the regulator is bad.. this will cause full charge of the alternator to enter the system.. this uses the battery as a regulator and will cause overheating of wires and relays..if the alternator can be removed and tested separately(most can), do this and see if this is the case..replace if bad..good luck..

If it has an electric fan a would replace the coolant temperature sensor.If it a mechanical fan i would replace the clutch on the fan.

check waterpump and cooling fans

a 2005 ranger blows fuses when is turn fan on.

Could be a stuck or worn out thermistat, also listen to the fans on the truck.. sometimes if they are electric they burn out or the sensor is burnt out

This is very common on 2003-2007 chevy trucks and suv's.
The stepper motors behind your cluster go bad. Do not go to the dealer, instead go online and look up cluster repair for your yr. of silverado and preferably in yor area. Price should range from 115.00-200.00 for all new motors, mine has 7

Actualy check the clutch fan. It might still turn but its not engaging annd is having no effect in cooling the motor.

overheating has a few possibilities.
thermostat.
low volume from water pump.
air lock caused by a small leak
cooling fan not coming on. from radiator fan switch or relays.

have the system pressure tested,
check the fan operation,electric or clutch fan.
