I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.

Have you bleed the cooling system after changing these thermostats if not it could be vapor locking and pushing water out of resevoir

Why is my 2003 chevy impala stalling while driving or while idling for awhile and not starting again for several hours?


Have fuel pressure checked. Check for spark when it won't re-start by using a tool designed to check spark or hold ignition wire barely away from module , while someone tries to start engine in short bursts. Try not to make contact with vehicle besides this hand and keep clear of moving engine parts. Best to use rubber glove there is a chance you may be shocked.

2003 chevy impala engine stalls whats the issues


When the actuator malfunctions, the engine gets no signal for idling speed and stops working. Clogged or restricted EGR Valve: If your EGR valve is clogged, dirty, or defective it can cause your car to stall, idle erratically, or sputter, depending on whether it is stuck open or closed. I would start there.

P0171 and P0174 are lean codes. There is likely a large vacuum leak or the MAF is bad.

Try starting the car and wiggling the connector for the MAF sensor. Also try tapping the MAF sensor. If the idle changes or the car stalls replace the MAF sensor.

The second shop should recognize that these codes don't have anything to do with the ignition module.
