Is the vehicle really over heating would be the first thing to address . If this vehicle was brought to the chevy dealership I work at , hooking up the factory scan tool to see what the PCM - engine computer is seeing for coolant temp . Too see if the cooling fans work , too see what temp info . the PCM is sending to the instrument cluster . I know GM had stepper motor problems in the instrument cluster . The step motor is what makes the temp , fuel , speedo , tach , gauges needles move . Just replaced a cluster in a 2005 chevy cavalier , temp. gauge goes full hot after just starting the vehicle . The cooling fans should kick on at around 223 degress , do the cooling fans come on ? Given the amount of electronics on these vehicles , it maybe best to take it to a qualified repair shop . That knows how to test these systems . Without testing I would only be guessing as to what could be wrong , Unless your prepaired to replace a bunch of parts , because your going to get a lot of different cause's from on here . Testing is the proper way to finding the problem . If you don't have a scan tool to view engine sensor data parameters , temp sensor. At harbor freight they sell a
Non-Contact Infrared Thermometer With Laser Targeting. This will show what the temp is .

Sounds like it's your battery cables, either a bad ground cable or the positive cable. I would replace both and see if that fixes your problem. Your local auto parts store has them and that is a pretty easy job. I’m happy to assist further over the phone at https://www.6ya.com/expert/jeremy_677dced97ad9bddf
The wiper arm springs are weak,just grab a used set of arms as most ventures wipe great.People who stick their wipers straight up,usually when freezing rain is coming ,ruin their wiper arm springs and have less wiping pressure too, so have to replace their arms at some point. PEOPLE STOP LEAVING YOUR ARMS IN THE UP IN THE AIR,OFF THE GLASS POSITION.
You can't disable it ! It's software programmed into the PCM - engine computer . If it doesn't see an enable message from the BCM or theft module it won't turn on the fuel injector's . They do sell a by pass module on the internet. Do know for sure mite be able to turn it off with a factory scan tool .
First,
Did they change the coolant temp sensor?
The one that sends the engine temp to the computer,not the one for the dash temp gauge.
Next,
If the engine has a leaky fuel injector it will start great cold but have trouble starting when hot unless you let it sit for awhile to evaporate the leaked fuel which would be around 2 hours.
Try holding the throttle wide open when it fails to start when hot,if that helps start it quicker then it is most likely a leaking injector.
Also when/if it starts hot look for black smoke from the exhaust as it starts
Sounds like a dry/failing bearing or power steering pump noise. You first need to try to track down where the noise is originating, and the most likely place is at the front of the engine.
I would start by listening with the hood up while parked with the engine running and the noise present, and seeing if it is coming from there. If so, the most likely cause is something connected to the belt - e.g. AC compressor clutch, tensioner, power steering pump, or generator. Can also be caused by the belt just slipping (warn out belt, tensioner not working properly).
This is how I flush the heater core...go to the garden department at Wal-Mart and get a 5/8 - 3/4" female garden hose connector similar to my picture...remove the upper heater core hose and connect your garden hose to the connector then to the heater hose and secure with a hose clamp. Remove the lower heaer core hose and point it to the gound, then turn on your faucet and run clean water thru it...
What you need to do is to change the oil seal on your engine and the gasket, I can assure after you change this parts there will be no leak on your engine.

With engine running, steering turned hard right or left, can you see the fluid churn in the power steering reservoir? If not, maybe one of the power steering lines is blocked?I just wanted to add, with some makes and models. With everything off, I remove the power steering belt. I take the return line loose from pump, aim into container, rotate the pulley by hand, see if any fluid comes out of return line? The return line should be low pressure, usually held to pump by hose clamp. The high pressure line has threaded fittings.
Drive cycles can be done in about an hour. 15 minute intervals.
First at highways speeds. Second at 45 MPH. Third at 30 MPH. Fourth at stop and go traffic. So from the highway to the city. Or replicate it on country roads. Just a note. drive cycles don't really effect emissions. You may won't check state requirements, or take it to another shop. or ask another shop.
