Hi I’m here to bug you lovely people.

I just did all my belts, fluids , brakes etc about a month ago .

Two weeks ago I started getting intermittent high pitched squealing at startup and acceleration. It only happens sometimes but it does happen every time I drive.

Hoping someone can help

Thx!

Agreed. If not an issue before, tighten up the belts, most likely the alternator belt. New v belts will stretch some after some use, and on startup is usually when the clutch fan pulls the hardest, or at high rpm high temp.
