the temperature sending unit is right under the throtle body .
had a problem with my 2001 impala 3.8. dealer said it temperature sending unit, then water pump neither fixed the problem. finally replaced the thermaostat and that worked. don't know if that is your problem but may be something to think about.
either 3400 or 3800 No Impala SS was produced in 2001.
.60
On exhaust pipe after cat
depends on the car i have 2001 Buick regal and its a bigger motor than a Chevy impala.
it is just above the oil filter remove oil filter and then remove the oil sending unit
back side of engine toward the fire wall.
No they won't
A 2002 Impala with the 3800 engine requires 4.5 quarts of oil (5w-30 is recommended).
An ACDelco PF47 is an original equipment oil filter for that 04 Impala 3800 engine.
you put series 11 do you mean 1 no series 2 not a truck
200 HP on the standard 3800 V6 series II, supercharged version in the SS models produces 240 HP
