    Weird "squealing" noise

    A week or so ago on a rainy and cold night, I started getting this occasional weird squealing noise when driving in first and sometimes in second. It goes away once I am in third gear. Since then it still occasionally screeches. Like when going down to 2nd gear for a turn. Or even in neutral and revving to around 1-2k rpms. I've also noticed that when its cold and rainy the clutch pedal feels a little "squishy" like its hesitant when springing back up. Is the cold/rainy weather causing this noise? Or is there something else I should look into?

    Check the oil level in your transmission, and top up if necessary. While you're at it, even though it's likely not the cause, check and top up the rear diff oil too.

    Check your clutch fluid reservoir. Look for signs of clutch fluid inside the cabin near where the clutch push rod goes into the fire wall. You might want to try and flush the clutch fluid if its dirty/contaminated/aerated. Pilot bearing?

    Checked the transmission & diff oil, those were fine. Fan and belts were lookin fine as well. Ill check the clutch reservoir and stuff later when I'm out again. It wasn't raining today & usually i get the noise when it is raining which is weird.

    The belts look fine? I assume you checked belt tension. They stretch out and squeal.

    It's a slipping belt. Happens when there is a little moisture on the belt.
    Just carefully tighten the alternator belt.
    You need to loosen TWO bolts B-4 you start cranking on the adjuster rod.
    Don't do this in the dark.

    I saw from your profile you have an 83 with the 5M, which has twin V-belts for the alternator. You also appear to have added some lighting. In the rain you are using your lights, plus the wipers and maybe the windshield defogging fan and auxilliary lighting. This overstresses the stock charging system which was never strong enough for these cars in stock form, let alone with add-ons. You may want to look at the high output alternator swap thread in the FAQ section to upgrade your charging system, as well as replacing the belts.

    '82-'83 is different than what I work on.

    Thanks,Dan.
    Add that you have an '83 in your signature please,California boy.

    The spongy clutch pedal is probably air in the system. Time to bleed 'em. Possible leak(s).
