2004 chevy impala radiator removal 3.4 engine


There is a very detailed write up here:
http://www.impalaforums.com/diy-do-it-yourself-how-to/239662-radiator-replacement-visual-walkthrough.html
The radiator is the same for both the 3.4 and 3.8 engines as well as various other GM vehicles around the same year. The cheapest radiator I was able to find was from Amazon.com: http://www.amazon.com/gp/product/B000IYPQXO?psc=1&redirect=true&ref%5F=oh%5Faui%5Fdetailpage%5Fo00%5Fs00&pldnSite=1
It's a fairly simple process, my 17 yr old son was able to do it all by himself. Don't forget to buy new radiator coolant and some Transmission fluid as you will lose about a quart worth when you pull the old transmission out.

I have a 2004 impala, how do I find the temp sensor? Already changed radiator, pump. The fans won't turn on until I turn on AC. Pls help


You will need a scan tool to read the coolant sensor, or you can just throw away $ by replacing it blindly. It is located by or on the thermostat housing.
