sticking thermo? bad water pump? clogged rad?

[NemeGuero]

K so driving to work this morning (7miles) 45mph roads, baby shifting at 2.5k rpms.. my car temps jump to hotter than they were during ASB in the middle of summer in the desert driving on htm.

I was hitting 230 F. I pulled over and shut the car off. Then I could hear a gurgling and swallowing of water by my engine..

turned the car back on and temps instantly shot back down to 160 F.

Once I got to work the car sat cool in the parking lot.

The problem is intermittened and will come and go. Out of nowhere temps climb even with air flowing through the radiator and little to no engine load.

then randomly the car will cool itself down.

There is water in the rad and in the over flow so I'm not empty/low.


COOLING STUFF:
1/2 bottle water wetter with distilled water
nismo thermo
nismo rad cap
altima fans
greddy mss ( with digi temp readout)


I'm thinking it could be a failing water pump (because the problem comes and goes, and once its gone it mostly stays gone...)

Or a thermostat thats sticking and not opening when it needs to be.. (thing is fucking a month old) and then open when it feels like it.. or some shit.

Lemme know. I got an event next weeeeekkkend.
