Question about 1998 Ford Windstar

1 Answer

Coolant temp is normal while idling, cools off when fans cut in

When vehicle is idling the temp reaches normal, but when vehicle is moving and the fans cut in, the engine temp drops out of normal range, and when this happens, the heater is hardly blowing hot air. This is on a 1995 Ford Windstar, with a 3.8litre engine. the coolant level is right up. Could this be the sensor that regulates the two electric fans?

I would check to see if the stat is working right, do you have rear heat on this vech? . if you do you may have a air pocket, the windstars have a metal tube coning from the water pump that gose to the heater core lines for the rear heat and they like to fail. they get a pin hole leak that hard to find, the water pump also likes to fail also, not moving a enough fluid under load the ends of the inmpler wear down

I have a 2002 Honda oddyssey exl and I just replaced my radiator and the fan with the metal housing. When should the fans come on in cold weather?


fans only operate when the coolant temp exceeds the preset temp setting
the engine runs and warms the coolant and eventually the thermostat opens
coolant flows and in really cold weather the air around the radiator ( especially if moving) will keep the coolant sufficiently cool so that the fans will not activate
The fans may switch on if it is left idling for a period of time as there will be no air flow from a moving vehicle

Cooling fan is acting strange car is heating some when idling how can I trouble shoot or fix


It is normal for a temperature gauge to fluctuate when the car idles, you will notice 20 to 50 degrees bounce. As long as it is not going into the red or blowing steam don't worry about it.

The electric fan that cools my radiator is not running.


The radiator fan should come on when car reaches normal operating temp,With engine at Idle and temp normal feel the top radiator Hose ,it should be hot,If no then Engine coolant is not moving-cause could be an "Air lock" if that is the case,turn key off until it cools then disconnect top Hose and start engine,at normal temp,you should have Engine Coolant coming out,turn key off let engine cool;reconnect and refill with a 50/50 mix;

Back to the Fan problem;the Fan should come on when engine temp is normal,if not turn the Air-Conditioner on,radiator Fan should come on at any temp;two checks ,one is the Fan Relay ,located in the under Hood main power supply box;There will be 3 or 4 relays for different systems since they are of the same part number swap and see if problem is fixed;if no check the Fuse in same power supply box;You said fans spin so they are not locked up;Take an eight dollar D.C. circuit tester,they look like an ice pick with a clamp for ground attach,to ground and with the fan plug disconnected see if you have voltage; ,You can have a continuous fan by finding a wire close to the fan that has power when the key is in the on position,take a wire and attach to that wire;

When the radiator fans stop functioning properly, the engine temperature will rise as there will be insufficient airflow to cool the radiator. The spike in temperature will be the highest when the vehicle is idling at a stop light or just stopped, but should subside once the vehicle begins moving again.
get the fan cked out.

Your vehicle has two fans controlled by three relay's . Both fans run together at two different speeds , low an high ! With the A/C on the fan's will run all the time while stopped at stop sign or idling . Any other time the then only come on when the coolant reaches a set temp. The ETC - engine coolant temp sensor is a input to the PCM - engine computer . When coolant temp reaches 212 degress the PCM energizes the fan 1 relay turning on both fans at low speed . This is very complex ,your best bet ,take it to a qualified repair shop.

You probably need to bleed the cooling system properly.

Open the cooling system bleeder screws.

Slowly fill the cooling system with a 50/50 coolant mixture until coolant runs freely out of bleeder screws.
Close the cooling system bleeder screws
Install the coolant pressure cap
Start the engine.
Run the engine at 2,000 - 2,500 RPM until the engine reaches normal operating temperature. (midway on gauge)
Allow the engine to idle for 3 minutes.
Shut the engine off.
Allow the engine to completely cool.
Top off the coolant as necessary.
Run engine again at 2000 - 2500 RPM until the engine reaches normal operating temperature.
Allow engine to idle until cooling fans come on. It should come on with the gauge about 3/4 of the way to red. - if it gets to where is touches the red, shut down immediately.
When the fan comes on, put your hand behind the fan and observe the temperature of the air coming from the fan. It should feel hot. If it is blowing cold air, the coolant is not circulating through the radiator like it should. This could be caused by lots of things including an improper/defective thermostat, corroded water pump impeller, or a blown head gasket.

Radiator fans don't keeping running to keep the temp constant of the coolant


the fan only runs when the coolant temp reaches 225-230 degrees F, the temp will not remain constant, it will climb towards hot and then the fan will engage and bring it down, this is normal operation

I have 2003 grand cherokee with 140000 miles that overheats at idle. as soon as i start moving again, the temp goes back to normal.


You have two fan's on your truck, 1 is a fan clutch runs with the drive belt, 2 elec fan motor, with test light and engine running at normal temp, just a little bit above 1/2 way on your temp gauge check voltage at elec. cooling fan harness if you have voltage at one of the two wire's and fan don't turn on, bad cooling fan motor, on the fan clutch after you check voltage at elec. fan motor turn engine off, with your hand spin drive belt fan if it spin's freely bad fan clutch, replace it.Also check cooling level.Hope this was very helpful

Make sure the cooling fans are working when the engine reaches above normal temp,if they are not ,turn the ac on,and see if the cooling fans come on,if so,replace the coolant temp sensor,if it has a clutch fan,then replace it,for it is not staying engaged ,and is not turning fast enough to cool the radiator.
