Get a genuine Nissan one, always better. Had similar problems with mine, it would not warm up at all on a cold night, but i do have a 50mm all alloy radiator too.

What does ya'lls aftermarket gauge read for coolant temp coming out of the head (not post radiator) when cruising along on the highway?

Bump, just curious what the answer to my question would be.

I don't have an aftermarket gauge on mine. All I know is that Calumsult shows ~170 cruising down the interstate when it's warm lol.

Yes it does. Both my B13's have done the same thing. Warms up ok until I start driving then temp slowly drops off. Both had tstats stuck wide open. Both have been normal since replacement.

It will warm up fine to op temp then after a few miles down the road, temps start falling. You're spot on about temps, I didn't notice this in my second B13 until it got down to ~50 in the mornings. With the GTi-R radiator it cools down pretty quickly.

Lol, DJ and I drove my SCC car XC like this from CA, at night as we got further North, we had to back off a bit in the Midwest so the temps would stay reasonable. At 80-90 mph the motor would slowly go down to C. Had to skip using the heater other than as needed on the windows, too. Kinda cold in April at night in Ohio. Original on left, replacement on right:

All the cap is going to do is raise the b.p. of the coolant mix. The OEM is about .09 IIRC. It does not really even come into play until the radiator temps are hot.
