Hey guys I’m going to show y’all how I replace my radiator for a 2002 Chevy Impala 3.8. Also where are some parts like the coolant level sensor, water reservoir, and so on. Okay there are some things you need to know about your radiator “from experience with this issue b/c of time consuming” make sure you know the size of the radiator core from ½ inch to 1 inch make sure y’all know for sure. I hope that anything I did helps someone like me before a lot of people gave me good advice. THANK YOU CHEVY LOVERS I’M JUST TRYING HELP JUST LIKE THIS FORUM DID ME.

Remove battery and remove the plate were battery sits.

Unplug small connection and loose up the big clamp. Unscrew two bolts to take air compartment of without taking the air filter off. Do not disconnect pmc computer inside the air compartment just pull it out and move it so you can take off the back of air compartment.

After pulling carefully the pcm computer move to side and pop up the air compartment like this.

This is the pcm computer and remember don’t unplug anything just move it away so you have room for radiator and fan together to come out.

Pop clips that hold the wires from the pcm computer.

Next you’re going to take off the wire retainers on the fan shroud so you can move them out the way. Unplug the connections to the fan and make sure you know were right and left connections go to on fan. Move wire connection out the way.

After all of the instructions above the radiator is going to be loose just like a kids baby tooth ready to come out. Slowly push radiator towards motor like a 15 degree angle towards motor and pull up nice and slow, easy does it. Radiator and fan came off perfect.

![Image]()
After removal of radiator with fan find the coolant level sensor and remove with flat head screw driver.
![Image]()
![Image]()
Inspect new radiator to old radiator. Make sure that they are the same size of core as old one. On my new radiator I had new nipples for the trans cooler lines if they are bigger or smaller change them to the new ones.
![Image]()
![Image]()
![Image]()
Take both screws off the fan and take the clip off too so you can take fan off old radiator. On coolant level sensor put the same one or replace coolant level sensor. Put back fan to the new radiator and put the clip back. Put bottom rubber insulators or replace them. If they keep falling off put tape around nipples and put back.
