Default Need Help ASAP..

I'm new here. I had a friend helping me with my truck. 2000 ranger XLT 4x4 4.0 V6. I needed to install a fan clutch. In the process he broke a sensor next to my thermostat housing.. He also nicked the water pump pulley.. What is the sensor and how can I replace it. Also can I file down the pulley? Here's a couple pics. Thanks in advance..

What is broken with the sensor, the sensor itself or the plug? If it has a single wire running to it, it is the engine coolant temperature sender for the dash gauge. Cheap part, easy to replace, just remove it and install a new one. There will probably be some coolant leakage FWIW. You will need to retop it back off. I usually teflon tape the threads in such a fashion that there's still a good ground between the lower intake and the sender threads.

The pulley, I would sand the rough edges with some very fine grit sand paper "with the grain."

What does it sound like? Does change with engine speed, when you turn the steering wheel, turn on the a/c or defroster, etc... It will help us figure out what may be the problem.

Its the sound of a swelling pulley.. It all started off with a light swelling sound. I replaced the idler pulley. It didn't make any change. A couple days later I bought a new serpentine belt. The noise went away.. I sprayed the barring of the pulleys with belt dressing too. 40+ miles and a few days later the noise came back. Only under load about 3K RPMS and 20+ MPH. I sprayed a little belt dressing and nothing. So I started by replacing the tensioner pulley. Nothing. Next was the alternator. Seemed to work. 1 block into the drive the squeak came back under load. Next I replaced the fan clutch. Seemed to be fine and then it started to squeak again.. Today I replaced the water pump. It seemed to be worn down. The barring made a slight pitch when the impeller would spin. I thought I found the problem. NOPE.. I was told there are 4 sized belts for the 2000 ranger but nobody has them.. Now this is where I am..

Sounds like a squeaking pulley. It doesn't change with the wheel turned to the left or right. Its the same with the ac on or off. I haven't tried the defroster yet. I'm going to try to start it without a belt tomorrow morning to eliminate the internal problem.. Just stumped.

Sounds like your headed in the right direction. If the squeal persists, a stethoscope may help pin point where it's coming from. Just don't run it too long with out the water pump turning.

I have found on my 2001 the only serpentine belt that will not squeek is the Gatorback. And no belt dressing. I would recommend the idler and tensioner as those are weak points too but you already hit those.
