Boiling coolant
Did reading and im sure its either the t-stat or the headgasket.
And after a quick romp to and from town.
Got back and my coolant was boiling.

I checked the t-stat (it slowly opened in boiling water)
And i changed the turbo coolant line
It had a "skinny" spot in it,
would that of caused it to boil the coolant, since the flow would be slowed?

PIcs

Only when it gets really hot. But I have golden eagle head studs so I don't think the head is lifting or the gasket is blown.

What radiator and fans are you using? Going through town are you sitting at long stoplights a lot?

Mine hits 230F at long ass stoplights. But its also 100F outside

Dont know temp for sure, i only have the oem dummy gauge.

koyo radiator
twin 10" or 12" fans (cant remember) from an online store.
They still work, I see and hear them. I can even feel the hot air from my window when im sitting still.


I dont sit for too long at lights,
but when i got home it was boiling. I had been driving and hadnt been at a stoplight in 10+ mins.

Just change your thermostat and reseal it.
This recently happened to me and even though the t stat I had seemed to work fine, I changed it out, took out the radiator and pressure washed it ot from both sides and straightened all the fins I could and it has never happened again. Plus I took the opportunity to upgrade to a nismo t stat. Car runs cold as hell now my temp doesn't even get to the halfway mark. Driving on the highway my temp gauge fluctuates from(by the way I have a NX digi cluster so my gauge is in bars lol)..
