1996 Mazda Protege DX 4 Cyl 1.5L
What's causing the screaching sound on starting cold engine?
The sound goes away in 10-15 seconds, but it's ear piercing. The sound shifts tone when I shift from park. I've had this problem for years, 3 sets of drive belts over the last two years, new water pump, air compression unit, other repairs and it's still there. What gives?
Several possibilities; worn / slippng drive belt, worn / faulty belt tensioner, worn idler pulley, misaligned drive belt or misaligned belt driven components.
