Hello all.....I have a 2000 SE with 125k miles on the SR20 engine. Well now upon startup the engine makes a horrible squeal. It then goes away. What could this be? Please help.....I love my car....she has been good to me.

belts. 100%.

and or tensioner

but replace the belts too.

more likely to be the belts than the tensioner but it doesnt hurt to check it out while youre in there

its a gear in the starter. when i replaced my starter that was squealling, no more noise.
