in a word, yes. Liquid molecules are much larger then gas (air). it is very possible to have a non liquid leak, but have an air leak. It also depends upon how the thread is broken. When it heats up, it expands and may seal up. When it cools down, it contracts. As the radiator cools down, it also causes a vacume (hence how the overflow tank works). Another thing to try is to start the car with the cooling system sealed. There is always a little bit of air in the cooling system. Spray a soapy solution on the bleed screw, and see if it bubbles as the car heats up and pressurizes the cooling system. YOu can always do a leak down test on the cooling system. Another thing is it can be a clogged radiator. How many miles on the car? nipper

all the questions you can answer

dust and dirt will get slung off by engine rpm. If you go in mud or snow, then you need covers. Both can pack in there and possibly make things jump. nipper -
You need a load. Turn everything on and rev the engine at 2500 rpms and see what you get. You can rev the engine all you want, but with no demand on the system, there will be no current draw. Doesnt take much to run an engine. nipper

So i am in Louisville, Ky. I drove here through the mountains of MD and WV. The reson i like the 2.5L DOHC is that if you keep the engine over 3,000 RPM it will just scoot up a mountain at 75. With the cruise control, it insists upon downshifting to 2nd gear and holding it past the peak of the mountain. My gas mileage was an a bysmal 19 mpg. If i disconnect the cruise while climbing, the car upshifts to 4th with the torque converter unlocked and just wants to run right up the mountain. With manual speed control, i got 24 mpg at 75-85 mph. In another thread someone said that there is a wire from the cruise control to the TCU. It seems that this is a signal to the TCU to use a more agressive shift pattern. If it ever warms up here (and as much as i hate doing elective surgery 700 miles from home), i am willing to disconnect this wire (think of it as a labotamy for the cruise control) to see if this erradicates this god awful behavior. Can someone (yes porc you too) find out where this wire is, and the best place to disconnect it? nipper PS, this is the first high speed drive in the mountains with the lift kit and the GR2's, and i had no qualms with taking the car up to 100 mph. It felt a little odd in the left twisties, but fine on the right ones. Blu was a bit of a handful at 70 with a 40 mph crosswind.
