03 Impala got hot, did I crack my block?
Chevrolet Impala 03,
all air in the RAD and loop must be removed, and if not the
ECT the heat gauge lies. to you;, so will PCM scans PID= ECT lie to and lies to the PCM . air pockets full of steam LIE.
so learn to let the engine cool off fully first
no engine told at all. 3.4 or 3.8L
the left side of the RAD is its cap, an new cap is cheap. and due.
take cap off fully cold, and must be full if not put in the correct 50% premixed coolant here, do not mix HOAT with others. color kinda a clue but dang not truth. ORange I think new.
but this is listed with all types, mixed.
PRESTONE AF3100 {AF3000} Prime Extended Life All Makes All Models Antifreeze/Coolant; Prime® Extended Life; All Makes / All Models; 1 Gallon
PRESTONE AF2100 {AF2000} Extended Life, Full Strength Concentrate; Extended Life; All Makes / All Models; 1 Gallon
the fill 1/2 the overflow tank with same and all hose on it and in it are not damaged.(missing, clogged, bent)
cap on.
1: see chocolate milk for oil dip stick end or OMG transmssion stick>?end.
2: see steam at rear tail pipe , hot engine ,warm day.
3: see carbon dust or oil drops floating in top of RAD NECK cap off dead cold safe engine
all that is DIY simple there are lots more tests using TOOLS.

leaky coolant overflow hose
what hose?, how wrong, fell off, say fell off,
ir blew off from hot steam that is very low coolant and or
just a bad thermostat or bad water pump , is pump belt OK?
frankly any 03 themostat is bad, they have 7 year design life.
even a thermostat that acts in random. a true risk running it here.
beyond this.
rad leak down tests
engine compression near equal and at spec,
scan tool scans, see what it shows. for sure ECT sensor reading wild and RAD full my be bad thermostat, or bad water pump
if see rust in coolant the pump impeller blades can be rusted down.
assume the best, find the low hanging fruit (failures and easy tests)
