Ive been a mechanic for a few years but have just never ran into a cooling problem that required a flushing.

So what do i need to do to flush out the cooling system in my car?

Ive also heard of back flushing.. How do i do that also?

Also , do i need to use chemicals from the parts store?

Engine is a 94 lt1.
