The harmonic balancer for the engine may be worn-out or loose, check it out! The noise is likely to come due to the friction.
Blaming the harmonic balancer for this problem is a real reach. The belt is slipping. Tighten the alternator to tighten the belt. There should be less than 1/2 in deflection(amount the belt moves when you push lightly on it) if that doesn't help much, change the belt. Sometimes if they have been slipping for a while, they build up ma glaze on them that will continue to allow them to slip[ and squeal.
Sounds to me like a main or connecting rod bearing seized. If the engine now fails to crank over when you try to start it, it's seized.
Have engine computer tested
electric fan runs of a thermostat shuts off when coolant is cool enought
Had same problem on my 03. Replaced the fuel and air filter and had plugs replaced. Ran like new after. Dont know which its was but a place to start.
Usually a sighn of bad alternator.
First guess would be the pick up coil in the distributor
time for a major tune up
it could be the main assembly relay under the drivers kickpanel
when the sterring wheel is turned sharply to park, the engine shuts off
fuel pumps about to go out -or more likely your electronic control module is failing.
That would be the connecting rod bearings and the crankshaft bearings saying goodbye. You have succeeded in destroying the engine.
What causes a 1998 Pontiac transport to run hot and engine shuts off
If the engine restarts it is probably not an oil issue. The oil pressure will go to 0 after the engine shuts off. You need to check for loss of fuel or spark when it dies off.
