ok here's what i think if i'm wrong on these some one pl correct me... ok for the number 3 check your thermostat may be it's stuck or flush your heater core one of the other or do both1: Under heavy accelerating circumstances (Drag racing) I hear a whistling sound, kinda like a turbo sound, but quieter. I heard it could be tranny whistling, I thought intake. Out of curiosity, what is that?
2: Occasionally the temperature needle will jump all the way past hot, till the needle stops. I tap the dash, and it goes back to normal. Why?
3: Heat blows real nice when I'm moving, but when I stop it's ice cold. I have new coolant, about a 70/30 mix with water. Is that normal?
4: On the expressway tonight coming home from work, the brake light and the battery light started flickering, and then came on, and flickered again. Voltage seemed to be around 10 volts or so, lights obviously dim. When I got off the expressway, the lights (battery and brake) shut off, and voltage stayed around 10 all the way home. I did test the alternator about 2 weeks ago and the diode pattern is bad, but it pushes the right amount of amps. The battery is also going, it tested good, low charge when it was fully charged (usually indicating a bad battery on its way). I do have to replace both things, but is that normal for that light thing to happen?
I'm sure I'll have more stupid questions for you all, and I'll post them then. Thanks for all the help, I really appreciate it!
and for the number 4 if your charge light and brake light is coming on it means your ALT is on it's way out and get your batt check if it's not good replace it as well when it happned to me i replaced my ALT and my BATT but after while it came back on like with in a week so i took it back to the place that i got it done the son of a B**ch who instoled my ALT has dameged my ALT wiring harnes so i had to replace that too (no charge ) so check your ALT wiring harnes .like i said this is what i think of it so if i'm wrong some body pl corect me
