Default radiator cap/ overflowing coolant

my 01 limited is still having cooling issues. I am now down to it just overflowing into the overflow tank and then spraying onto my exhaust and then the coolant temp going way up. When I pop the hood as its happening I can hear air coming out of the radiator cap. My original cap I had on the car that I accidently broke and had to replace was an oem one from the dealer and it said 18psi on it.

The replacement I got from autozone that they say is for the car says 16psi on the cap. Would that difference in psi rating make the car burp into the overflow more than it should? I have no oil in my coolant or coolant in my oil so I don't think its a head gasket problem. I was thinking of having the shop test the coolant overflow tank for gases that would appear if a h.g is bad. What are your guys's thoughts?

While searching I found this: every pound of pressure raises the boiling point of water 3 degrees. Your 2 pound difference should not make a big difference.

But lets find the real problem. If your fan working on both speeds (for non-turbo)? Are you running the correct mixture of coolant and distilled water? (50/50 mix s recommended). Is your radiator in good shape and not clogged up or partially clogged stopping the coolant from running around? Is there any air trapped in the system? Do you bleed it every time it overflows and you add more coolant?

I had my fans take a crap on me, those were just replaced last week and the issue still persists. I do not know the condition of the radiator at the moment or if it is clogged or now and when I refill it I use a 50/50 mix of the green crap from advanced auto. That stuff has been in my car ever since I bought it 3 years ago.

I had my timing belt and water pump replaced last year so I doubt the pump went out on me and I replaced the t stat, housing, overflow tank and hose, and the upper radiator hose earlier this year.

I also wasn't sure about the cap being the wrong one or not because of being able to hear air hissing from it when I popped the hood.

You need to CONFIRM that the cooling fans are running when they are needed.
You could have an intermittent problem with the fan wiring causing the over heating. My cooling fans would run good for a week or two then overheating came back. It was the wireing connector near the fan was burned inside

good luck

I have confirmed that the fan is running when it should be now that it was replaced. I am going to check for a clogged radiator in the morning.
