Okay so today I replaced my radiator cap and upper hose of the radiator as it wasnt the correct one and was pinching slightly.
I refilled the system, left the radiator cap off, and opened the bleed screw on the throttle body. I then started the car and watched the water shoot out through the bleed screw. I closed it and kept purging the system until the car was warmed up. I also opened the heater and turned on the heater blower and moved that back and forth a few times.
I took the car for a ride, and still the gauge would float a lot on hard turns. It would also go up a bit after sustained 4500+ rpms for about a block. Then would usually come back down to a where I could just see all of the top of the top mark on the gauge.
I got back and checked the top hose and actually felt a bit of pressure in it but if i wanted I could still pinch off the top hose. I opened the bleed screw while it was running and nothing came out. I opened the radiator cap and fluid started coming out of the bleed screw.
Yes, even after a 10 minute hard run at operating temp I can still open the radiator cap with no pressure behind it.
I cant figure this out. I cant figure out why the car is running a lil hot or why the gauge is floating a bit.
Am I supposed to be able to open the bleed screw with the radiator cap on while running and get nothing out until I rev the engine?
UGH IM l losing my patience
