'noise' persists after changing pulleys & belt... - Page 2

or its acting the same as WD40 and lubing the berrings also dampering the vibrations!

if it looks like the soap is melting, then maybe, you could be right. maybe the heat of the engine would do that but I would think the rotation of the belt would spit the soap outward and not towards the bearings.

as for the belt, I think there was 2 k060915 and a k060910 Gates.......
Soap will let the belt slip unitl it all burns off....

Only 2 basic resosons that a belt will squeel.....
1. Slipping from to much drag.
2. Wrong tensioner pr belt.

Keep us posted on what you find.....

The serpentine belt has a drive side and an idle side. The drive side is ribbed and is used for the high load components comprising the crankshaft drive pulley, alternator, power steering pump and A/C compressor. The idle side is smooth and powers the water pump, idler wheel and tensioner wheel. The belt itself is not likely the problem provided the tensioner is working properly.

You probably put soap on the smooth side of the belt and since this affected the noise, then I would say you need to look at the components that are directly affected: idler, tensioner and water pump.

The tensioner is under a lot of spring pressure so test that first. You need a long bar and 15 mm socket to release the tension and it should snap back very strongly. If not then it is not right and needs to be fixed. If it is OK, then you need to remove the belt and recheck the bearings on the tensioner and idler pulleys and the water pump bearings.

Where is this part located?

Which engine & how many miles?

Can you be sure that the noise is caused by this part?

Did you replace it yourself? Easy or difficult, Expensive?

Thanks, John aka JayKay

The cam shaft position synchronizer is located where the distributor used to be, and it can make a lot of noise.

My 2004 with 85K miles started making an intermittent squeak, sounds like a belt but sounds can be misleading. Is this synchronizer a likely source?

Here is a link that will help you to determine if the synchronizer is your problem. It also contains information on how to replace it. Sounds doable and a probable cure for your problem. Here it is:

Hope this helps.

My problem very closely so I'm about 99% sure we've found it.

I have a couple more questions, appreciate your patience!

1. I'm still not quite sure how to get to this part. You said where the distributor used to be and I'm guessing at the right end of the motor as you stand in front of the car looking at the motor. Between the cylinder banks on top of the motor.
The author of the Taurus club post said you had to cut the plastic tray that supports a bundle of wires.
Do you know where I could look at a photograph or diagram?

2. I replaced the spark plugs recently, the old ones looked original. The car ran much better but developed a "miss" under load after about 1000 miles. After about another 1000 miles, the "squeak" started. Do you think the missing or hesitation could be caused by the camshaft position sensor?

Thanks, appreciate all the help. John

You are correct about the sensor position. Specifically, the sensor is located very close to the thermostat elbow. You will see a black plastic capped component on the top of the intake manifold beside the 3/8" bypass coolant hose and the engine temperature sensors.

I do not think the miss had any effect on the sensor making a noise. Do you still have the miss? My 3.0 OHV engine does not like Motorcraft platinum plugs and did not run very well with them. The gap kept opening up and causing poor running and starting problems. I think the standard Motorcraft plugs are better. I replaced the platinums at 45,000 kilometers with NGK platinums and find them excellent. Fixed my uneven idle and generally a much better component. There are other causes for a miss though, including fuel delivery, ignition wires and coil, etc, etc. Check the plug gap first though.

Hope this helps.
