Could someone please tell me what tool you need to remove an idler pulley off of a 97 ford f150 4.2 liter engine? I haven't pulled anything off the engine yet. I looked at it and there appears to be a star head bolt. Please help! Any info would be appreciated. It is squealing badly and I'm afraid it's going to lock up. You can hear the noise from 50 ft. away when the engine is cold, after it warms up the noise quiets somewhat unless you come to a stop, then it gets louder.

I found out by listening under the truck with a stethoscope that it's the crankshaft, I'm thinking the pulley maybe? It squeals really loudly close to the pulley. I was told that this is the first sign of trouble. One man told me that his sheared off(cranks shaft) shortly after the squealing started. I replaced the idler pulley, after a lot of hassle (I'm a maint. mech. not a truck mech. lol), & changed out the alternator. Has anyone heard of the crankshaft pulley squealing on a 97 f150 4.2 liter? And does anyone know how hard it is to pull this beast off? It looks to be a fair amount of trouble, but like I said I'm not a truck mechanic. Could someone please help? This is my only transportation and as a single working mother it is difficult to keep things going at times. I am very grateful for any advice here. Thanks so much.

To remove the PULLEY on the 97 is simple, four bolts inside. To remove the balancer behind u need to rent a puller from autozone. Not that hard either. Did u change ur belt. Also if, for some unknown reason it is the pulley, buy a underdrive one. Probably cheaper than a stock pulley, at a dealership. Also this website has tons of info on our trucks v 6 f 1 5 0 . c o m.

Did you find out if the harmonic balance is the culprit? Was the pulley sliding on the belt? Mine squeals loudly (sound like a turbo winding up) when it is really cold out. In warmer weather it has been fine. I've been meaning to change the belt out beacue I have nearly 80K on it and it looks like the tensioner is as far out as possible.
Yes it was the harmonic balancer. And boy was it a pain to get it off. I also changed out the pulley. Can any of you tell me if the shaft on the power steering pump is supposed to slide in and out of the psp? It's the only pulley on the whole truck that isn't stationary. Thanks
What is there on the crank pulley to cause it to make noise?Mine is making a bad noise when I start it and it is cold out.Get even worse when I turn the AC on.I was thinking it was either the idler pulley's or the AC compressor pulley?My motor is a 99 by the way, with a new belt.
Mine squeaks intermittently when I first start it but quits after about 15 minutes. Sometimes it doesn't make any noise. So far I've changed one of the idler pulleys and the tensioner pulley but it didn't help. Now it sounds like it's coming from the water pump. I guess as long as it doesn't get any worse it won't do any damage but I'm used to a quiet engine. Mine has 149,000 miles but it's still an excellent truck. I'm about to make another 3,000 mile trip in it.
