2002 Coolant sensor Location
Hi all,
Sorry if this has been asked before but I couldn't find an answer... I'm looking for the coolant sensor location on a 2002 Chev Impala LS 3.8. I belive that the sensor is bad because the low coolant light is coming on when both the Rad and the Resevoir are full. Any help is appreciated! (or possible solutions  )TIA Stew

Do you mean the coolant resevoir? It's actually on the radiator itself. Passenger side, on the edge/corner of the radiator, about 1/3 of the way down, "back" side, it's grey. It's basically right in front of your batteries positive post.

A low coolant light could also be a stuck thermostat... If it's stuck open you could get a light... I just had this happen... Changed out the thermostat and now the warning light does not come on... On the 3.8L engine you can replace the thermostat in about 10 minutes...

But..... If your problem is truly the coolant level sensor there is an excellent "How To" at: www.impalahq.com
Go into the How To" section and you will see exactly what you need to know about changing the sensor...
