1995 Lt1 Camaro cooling fans operate like this; Cooling fans (2 fans) come on 30 seconds after start up on high, stay on while driving, and turn off when brakes are applied. Stock car, no mods.


Did you have it checked for DTC'S - diagnostic trouble codes ? The cooling fans are controlled by the PCM - engine computer , with the use of three relays ,located in the under hood electrical center . Do you know how to do electrical testing ?
Relay Driven Dual Cooling Fan Diagnostics Looking at wiring diagrams i don't see any connection between the brakes an cooling fans .

The primary radiator fan does not come on.


Check Maxi fuse #3 60 amp in the under hood electrical center #1 .This is power for the #1 cooling fan . Also check the #1 fan control relay in the same under hood electrical center .
These vehicles use 2 360 mm (14.2 in) cooling fans to aid air flow through the radiator. Electric motors drive the cooling fans. These motors are attached to the radiator. Motor size varies with each engine option.
A coolant temperature switch activates the fan motors. This switch regulates voltage to the cooling fan relay. This switch operates the fan whenever the engine coolant temperature exceeds 110°C (230°F). For location and diagnosis, refer to Electrical Diagnosis. A transducer can also activate the circuit, depending on the A/C compressor head pressure going to the condenser.
The engine cooling fan relays provide the high current required for the cooling fan motors using a low current signal coming from the Powertrain Control Module (PCM). This signal is a function of various inputs.
Refer to Electrical Diagnosis for further information and diagnosis of the cooling fan relay.

Where are the fuses and sensors for the electric engine cooling fan


fan electronics start at the sensor in the cooling system, and sends a signal to the ECM which in turn closes a relay and turns on the fan/s
There are 2 fuses in the system. one for the power to the sensor and one for the power through the relay
I suggest an accredited auto electrician with experience on your vehicle to quickly find the problem point.

Electric fan does not turn causing engine overheating when car isn't moving. Turning on the heater helps.


The inoperative cooling fan needs to be diagnosed,run the engine until it reaches 229degrees and seeif the fan gets power to turn on if so then replace the fan if not check the wiring and cooling fan relay and repair or replace as needed.

Doe's it have fan for cooling , it's over heat, please help


Yes, they do have cooling fans. Some Grand Cherokees came with just an electric cooling fan, some had a hydraulic cooling fan driven off of the power steering, some had a mechanical clutch type fan, and some had a mechanical clutch type fan and electric fan. It really depends on what type off fan you have. It sounds like you have an electric fan that the fan relay has gone out. The fan relay is located under the right front portion of the bumper. Hope this helps.

Best of luck.

Code p1652 on a 1996 pontiac grand prix does anyone know what it means the book for computer codes is incomplete


Trouble code P1652 means: Cooling Fan 2 Relay Control Circuit Malfunction

I would start by checking power supply to the cooling fans,making sure the coolant system is full,& using a scn tool to verify the proper operation of the cooling fan system.Here is some info to help you.

The Powertrain Control Module (PCM) controls the operation of the cooling fans. This is accomplished by providing a ground path for the cooling fan relay coils within the PCM. The relay contacts will close and complete the circuit between the fusible link at the battery junction block and the fan motors. Whenever there is a fan ON request both fans will be running.

Power for the fan motors is supplied through a fusible link at the battery junction block. Battery positive voltage is applied to the cooling fan relay contacts and coils. The cooling fan relays are energized when current flows through the relay coils to ground at the PCM. The cooling fan relay #1 control circuit is used for low speed cooling fan operation. The cooling fan relay #1 control circuit and the cooling fan relay #2 and #3 control circuit are both grounded for high speed fan operation. The cooling fan relay control circuits are monitored by the PCM. Before using the Electric Cooling Fans diagnostic tables be sure to perform the Powertrain On-Board Diagnostic System Check. If diagnostic trouble codes P1651 or P1652 are present, use the appropriate DTC diagnostic tables prior to performing Electric Cooling Fans diagnostics.

Important:
When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. It is important to perform the Powertrain On-Board Diagnostic System check prior to diagnosing the engine cooling fans.The PCM will complete the ground path for cooling fan relay #1 under any of the following conditions:
- When engine coolant temperature exceeds 105°C (221°F)
- When A/C is requested and ambient temperature is greater than 10°C (50°F)
- When A/C refrigerant pressure is greater than 190 psi (2 volts)

For high speed cooling fans operation, the PCM will delay control of the cooling fan #2 and #3 relays for 6 seconds. The 6 second delay ensures that the cooling fan electrical load will not exceed the capacity of the system. The PCM will complete the ground paths for cooling fan relays #1, #2, and #3 under any of the following conditions:
- When engine coolant temperature exceeds 113°C (235°F)
- When A/C refrigerant pressure is greater than 275 psi (2.9 volts)

If a problem that involves the low speed cooling fan relay control circuit (cooling fan relay #1 control) exists, DTC P1651 should set. If the problem affects the high speed cooling fan relay control circuit (cooling fan relay #2 and #3 control), DTC P1652 should set. A problem with the ECT sensor should set DTC P0117, P0118, P1114, or P1115. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis table. The Electric Cooling Fan Diagnosis table should be used to diagnose the PCM controlled cooling fans only if no DTC is set.
Hope this help to solve your poblem (remember rated and comment this help).

Electric cooling fan on ford five hundred not


Check the fuse for the fan and you could test to see if you have a voltage running to the fan when the car starts to overheat. If you have no power to the fan then trace the wore and see if you cant find the problem. If you have power then the fan motor is most likely bad.

1999 jeep grand cherokee laredo is engine fan belt driven or electric?


The radiator cooling fan used on the 4.0L engine is
an hybrid fan design. The hybrid fan system consist
of a low speed viscous driven mechanical fan and a
electrical fan.
The hydraulic fan used on vehicles equipped the 4.7L engine, replaces both the electric fan and the engine driven mechanical fan. The hydraulic cooling fan is integral to the fan shroud and is located between the radiator and the engine. The power steering pump supplies the hydraulic fluid and pressure to rotate the cooling fan blade, while the electrical part of the fan is controlled by the JTEC. The hydraulic fan drive (motor) consists of the three major components:
- Steering flow control valve
- Fan control valve
- Two stage G-rotor hydraulic drive
The hydraulic fan and drive is not serviceable.
Therefore any failure of the fan blade, hydraulic fan
drive or fan shroud requires replacement of the fan
module because the fan blade and hydraulic fan drive
are matched and balanced as a system and servicing
either separately would disrupt this balance.

Engine cooling fan


you will need an electric fan fitted to the radiator and bear in mind that you will need the appropriate voltage reading etc,so you need the right power source.Also you need to consider a thermostat fitted in the cooling system unless you want to run it on direct power.For any questions,please ask.
