Im not sure wat else to do....Ughhhh can someone pls help??!!!

Welcome to the forum.

Not sure what to say about the oil. but as far as heating up you'll want to check the radiator cap to see if it's maintaining correct pressure and make sure the radiator isn't partially clogged.

When it does start to get hot, is the fan switching to high speed. You can tell by just standing in front of the motor, hood open. The high speed fan makes a lot of noise, unmistakable from the low speed.

One more thing. are you bleeding the coolant system of any air that might be trapped?

Did you use an oem thermostat? They make different degree thermos, so you may have put one in that's much too hot, causing the car to run hotter before it opens.

What about the water pump?

Do you have any coolant leaking out causing air in the system? Leaking heater core maybe?

Do you have a proper 50/50 mix of coolant so it can displace the heat effectively? Just some things to check.

Not sure what you mean by "blinking for oil".

Had an overheating problem until today. Had cooling system flushed, replaced water pump, thermostat, radiator cap. Still overheated, shop said it was a blown head gasket or warped head. Didn't agree as there were no secondary indicators for head problems other than over heating. It would only overheat if driving over 45 mph. I let it sit and idle for an hour with no problems. Fan worked fine.

Found a couple of references on this site with the exact symptoms. They changed the radiator, problem went away. Today I changed the radiator, drove 30 miles at 70 mph, heater off, worked perfect. New radiator, $129.99 at Autozone, 2 hours to remove and replace

Good fix. Dumb Shop glad you didn't listen.
