Overheating issues

[19ramrunner]

Hey everyone, im in need of some advice here, got a 2019 5th gen etorque 5.7, it started having overheating issues a couple months back, I replaced the thermostat, no luck, I replaced the water pump, the reservoir and nothing, I could drive a couple of hours before I had to add coolant but today I found out I had a blockage in my radiator, I flushed it out, and now I cant drive more than 5 minutes before I overheat. I will note that I don't have any heat, so Im guessing my heater core is clogged up but I'd like to try everything before I take the whole cabin apart just for that. Any ideas would be great thanks!

Did you perform the coolant system air evacuation procedure?

"Evacuating or purging air from the cooling system involves the use of a pressurized air operated vacuum generator. The vacuum created allows for a quick and complete coolant refilling while removing any airlocks present in the system components"

What did you refill it with? Service data specifies the use of distilled water if diluting concentrate antifreeze.

I just went with a 50/50 pre diluted coolant, I lifted the front end and ran it for about half an hour filling as needed, it was bubbling which makes me think I may have a headgasket issue, im hoping not but just in case I got a tester im picking up tomorrow, so I'll update then!

I've seen them use a surgen type glove stretched over the radiator cap to test for head gasket. If it expands you've got problems.

So I just went out and tried that, at idle nothing happened, when I rev and hold it still nothing, when I let off it inflates for a couple seconds then deflates, am I screwed??

No, that's normal. And as the coolant heats up and expands, so will the glove. Poor test for head gaskets. Especially since head gasket failures don't always leak into cooling passages

If it was leak inot oil passage he would have a milkshake in the radiator.

Checked oil, it was normal no milky substance

Ive got a tester coming in the morning, I'll try it out and let yall know what happens
