I have a 1997 Ford Ranger 5 speed RWD with a 3.0L V6 engine. I have had a problem for about two years now of a constant engine squeak. It seems to go away with belt dressing so I figured it had something to do with the belt and the pulleys. I changed the idler pulley, the tensioner pulley, and the belt and it still squeaks. I then thought to check the A/C compressor clutch and it seemed to be coming from there, I sprayed some WD-40 on the clutch and the engine was perfectly quiet. I did this again a few more times and each time it quieted the engine. I was almost certain it was the A/C compressor clutch but after I changed it last night it was quiet, but this morning it started squeaking again. At this point I can't think of what the problem might be. Please post any information that might lead to the discovery of my annoying engine squeak problem.
I had a squeak in a 98 ranger with a 4.0 six, it was the under the intake manifold were the pickup was for the electronic ignition, looks like half a distributor (were a distributor used to be in older models), I had tried everything idler puller tension-er , new alternator, I was way off..
