well, at night, the car is rock solid with its temps. I drove it last night, temps were 85F, I did some WOT runs and ran a steep mountain....temps stayed right at 185F with fans on...occassionally fluctuated up to 195F.

Its only in hot weather/a/c on, that the car creeps up in temps...the other day in 105F, I turned on the A/c and watched the needle creep to 220F before I shut it down.

The gurgling sound is like a sloshing noise coming from the turbo area....maybe its water returning to the system from the overfill.


As far as the filler neck, there are a few dust bubbles at idle, and tons when I rev the engine up...at 4.5k rpms, the water level drops down deep into the neck and when I release the throttle is comes back up to the top with tons of champagn bubbles. We performed this with the hydrocarbon tester on the neck and it never changed colors.

The only spot I know of that could potentially cause any problem would be the radiator plug is cross threaded in, but its a very mild cross thread and its fit flush against its rubber gasket.



The motor is a mazda reman with around 50k miles on it. I replaced the thermostat not to long ago and replaced the 13psi ast cap the other day. I had this temp creep problem last summer and the summer before. In the winter there is NO flucuation in temp.
