Well after putting the 190 thermostat back and doing the glove test yesterday and again today I cannot see any air going in the glove. I had my friend crank it for about 10 seconds at the time while I watched, we almost drained the battery and nothing happened. Did this twice, different days, I made sure everything was sealed and no pressure was escaping.
Now I'm very lost. Is there a slim chance I still have a very tiny mini little microscopic air pocket and that's what is messing with Me? I'm sorry guys for being so annoying but I just feel so dumb and frustrated right now..
Don't get discouraged. Diagnostics can be a real pain and I know how frustrating this can be. That's what the community is here for, it's not necessarily fast but for the most part it's free and effective.
Let's break this down a bit.
The problem:
You're not experiencing overheating but you see pressure buildup in the coolant reservoir system
What you've checked:
Water Pump is new
Radiator is new
Thermostat is new
Pressure test indicated system is sealed
Glove test showed no signs of exhaust gas buildup
OK so using this I'd say there are a few things to look into still.
Temp Sender: The unit on the water pump housing that detects heat of coolant exiting engine. You say you're not experiencing overheating, how sure are you of that? Are you pulling readings from OBDII to confirm or just trusting your gauge? Simple test to check for functionality.
Temp Sensor: Sensor that sends coolant temp to the computer. If you are using OBDII to pull temps, are you sure that the sensor is working properly?
Radiator Cap: I don't think it's likely since hopefully you changed rad caps after each new radiator, but if that little jerk has failed then that would explain pretty much all of your symptoms to a T. If it doesn't hold pressure properly then it could be the source of your problem.
Leaks: You didn't mention if you have seen any leaks or puddles on the ground so I had assumed you didn't. Double check every coolant line & fitting and after running the engine take a good whiff, if there is a leak you will smell it. Also a good idea to get under the car and look up at the timing cover, sometimes there's a leak from the WP or the surrounding area that goes unnoticed as it heats up and boils off before hitting the ground.
Really take a good look at the intake manifolds, make sure that they are sealed well. For leaks I'd recommend getting a UV dye off of Amazon and putting it in your coolant, run it for a day or two then pop the hood and go hunting for leaks using a black light and yellow tinted glasses. If there is a leak this will let you know when your engine bay lights up like a Jackson Pollock painting.
Blockage: Have you run any flushing through the system? Did you put any HG sealant in at any point? Is there a gurgling sound coming from your vents when the heat is on, particularly when you rev the engine?
There's a lot of things to still run down, and the cause of your issue could be related to any one or several of them in combination. It could still be a Head Gasket/Head issue that is very small and only presents itself when the engine is warm.
Sounds like you've got a unique beast of a problem, but don't stress yet, take your time and approach it methodically and you will figure it out.
