Water pump was just replaced. Didn't help.

That's what I'm saying, do you think there is a possibility of the water pump still leaking? Or a cracked head/block? Maybe even clogged coolant ports.

There is no sign of water pump still leaking, as there was prior. If coolant ports were clogged, I don't think the issue would be so intermittent, and random as it currently seems to be. No idea about a cracked block or head... but wouldn't that noticeably affect performance?

You know what? I gotta take that back. I just checked, and there is a small amount of fluid beneath the water pump. Back to the mechanic it goes tomorrow... The saga continues...

My mistake again... no leak. Mechanic swapped out radiator cap. Not sure how that will help, but we'll see.

I'd first check for swollen hoses, front and back of motor.
Then check if your radiator is plugged or fan relay is out.
Check your coolant temp sensor and replace your thermostat with an oem
Check if your water pump is leaking

If none of those are a problem, let your car warm up all the way and watch your idle if it starts becoming erratic your problem is a BHG.

The egr valve in your intake won't overheat your motor but it will cause your hg to seep

Fan relays have been replaced. Temp sensor has been replaced. Water pump has been replaced. Thermostat has been replaced. Idle is fine. Have no idea what an EGR valve is.

The egr is located at the bottom of the air intake, above the valley or the V of the block between the head. Its for exhaust gas recirculation (egr) to reduce emissions for stricter smog regulations.

You have to remove your air intake to access it. It is recommended to be cleaned every 90k? I believe. If it is plugged it will cause your ecu to advance timing and causes excess heat in the cylinders and will cause a seeping HG in cylinders #3 and #6.

But the temp gauge says the engine IS getting hot.. That's the entire issue.

So you said the coolant temp sensor has been replaced? I can't think of anything else as a problem but a bhg but that would mean your upper and lower hoses are swollen.

Or could it be your coolant valve mounted to the firewall is semi plugged and slowing flow of coolant

But why would it be so intermittent, and why would shutting the car off for 10 seconds cause the temps to almost immediately return to normal?

The CEL is the Check Engine Light, are you having any of these?

Theres a writeup here

G2: DIY: Diagnosis: Pulling Codes - LegendWiki

My car still has a CEL, but for the only reason I know is that my VSS is on the fritz and needs to be replaced/rebuilt. The car drives fine and I have no desire to investigate, yet.
