Geo 3 cyl. head repair; weird noise on first start up

I just finished putting together my Metro 3 cyl. after it spit out a plug. I had the head done and installed new everything and now, when I first start it in the mornings, there's a weird rubber squealing sound that lasts for about five seconds or so and I looked and it seems the fan belt is rubbing against the timing cover. I checked all the mounting bolts of the cover. Anybody else had a similiar experience?

Yep. These covers will poke out if you are missing a bolt and the belt will rub. Also, there are different length bolts that hold the cover on, you may have too long of a bolt in one of the holes which is allowing the cover to stick out and rub.

The squeal is a loose alternator belt.

In all seriousness, this is a widely experienced issue. I had to throughly clean off the pulleys with a brush and brake cleaner, get a new belt, and make sure it was tight, then tightened it again 4-5 days later.

Okay, thanks, it was a loose alt. belt. I'm more used to the traditional v belt and not used to these serpentine belts. Now the engine is noise free and runs like a champ, thanks to all again.

The gatorback belts they have for these work pretty good. i had to cut one of mine sadly, when my a/c compressor started to seize :/

Woodie called the noise correctly.

The timing covers will bulge out at the bottom because oil leaks from a seal and causes the timing cover seal to swell. A warped timing cover may also be rubbing on the timing belt inside the cover where you can not see it. If this is the case, it will cause premature failure of the timing belt. Been there, done that. New timing covers are available from GM. Get the new seal, too.

I'm surprised you didn't shoot it. There are things called wrenches. Three whacks with a wet noodle for cutting a gatorback belt.
