Hey guys,

First post

My 1HZJ78 when engine is cold will squeal/screech fairly loud waking up the neighbourhood when accelerating in 1st/2nd/3rd. Had the A/C belt replaced but still makes the sound (not as bad). When the engine is warm, no screech.

Any ideas on what it could be and how to fix it? Pulley, tensioner?

Cheers
