I am a huge fan of Scotty kilmer from canada. I have a 2002 dodge ram 1500 4.7 with a ECM error code and a bad o2 sensor in my #1 bank. Last winter I had my rad spring a leak so I put some stop leak in it and it worked but than my heat stopped working so I ended up flushing out my heater core like 6 times and flushed and changed the coolent I replaced the rad and thermostat to be safe with fixed the heat issue but once it got to spring my truck started overheating on big hills so I ended up changing the water pump and fan clutch and put fresh coolent in aswell and it and it still overheats I am wondering if you have any idea I am thinking it is electrical but I did get the engine hot a few times so I am unsure. It doesn't burn coolant but a little oil. I appreciate anyone's time if they have a idea.

If it still overheats, watch this -
Did you get a new radiator cap and burp the system properly?
I did get a new rad cap but I don't believe I burped the system I am a bit of a novice. I will definitely give that a try. Also I forgot to mention my air conditioner condenser fan also is working properly.
