Carstarts 1 vsecond then stops with loud screetching noise only rund a second then screech any idea what wrong?

What do you mean when you use it. Do you mean when you push in the clutch pedal?? If so it is likely the throwout bearing is bad.

No idea

Need the car to find out

starter bendix is probably bad or it has stripped teeth on the flywheel. the acceleration problem sounds like you were in limp mode

Does it sound like backfiring or knocking or squealing/screeching or what ?

It's probably a worn or loose (or both) drive belt

The loud screeching sound is from the serpentine belt slipping over the pulleys a little. You probably got some radiator coolant on the belt or pulleys when replacing the radiator. When you connect both battery cables the alternator is trying to charge which puts a load or drag on the alternator which causes the belt to slip over the pulley enough to cause the screeching. The only way to correct this is to take the belt back off and wash it with warm soapy water to remove the coolant contamination from the belt. Then scrub the pulleys also as coolant was transferred from one pulley to another by the serpentine belt. Then replace the belt and put a little comet cleanser onto the belt to extract a little more of the contamination from the belt and pulleys before you start it up. And last but not least make sure the belt has the correct tension so as to prevent it from slipping. If you wait to long the belt will always be contaminated and forever screech. Do not buy any belt dressing for the belt. That stuff is junk and makes the rubber in the belt soft and leads to a premature belt failure.

Sounds like you may have a bad front wheel bearing.

It is your serpentine belt slipping on one of the metal pulleys and the friction is causing the high pitch screech. The belt may need to be tightened or replaced, which is an easy fix.

the screeching noise is most likely caused by a slipping belt or pully. transmission probably needs fluid and filter changed.

The only four rotating items under the hood are
engine
power steering pump
A/C compressor
and smog emission pump.
==== I would check the fluid level on the power steering first. Check for pink fluid leak on the ground,
==== Check the A/C system with the wheel turn to one side and APPLY ALL LOADS.
Example: high beam on,A/C max,radio on and deforster on.
This will give you system a stress test.
All eyes on the pully and locate to part that generate the loud screeching noise.
My bet is on the power steering pump.

Please post more info on the comment window.
I will follow up on it.
