Why is my Nissan Altima not cooling properly?
Still not cooling right. High side pressure too low at 150 PSI, low side pressure too high at 75 PSI. It looks like there is a problem on the high pressure line that feeds the evaporator in the dash, and not providing the restriction needed to drop the low side pressure to about 40 PSI. I will check this soon and hope that’s it.

I think mine might be the acceleration pedal sensor isn’t communicating properly with the ECM or the throttle position sensor. This theory is supported by the high rpm issue which might be the car going into “limp in mode” which is to allow the owner to drive the car to the nearest shop when accelerator issues occur.

How much coolant should I put on my car?
Using less than 50% antifreeze mix will limit it’s ability to prevent water freezing. Say if 50% mix would prevent freezing down to -45 degrees, 25% mix will only prevent freezing down to -20 degrees. I don’t know any exact antifreeze/coolant performance numbers.
