Just had the U-joints replaced last week. Now, a new problem. A couple days ago, i started hearing a noise from what sounded like it was coming from the top of the motor. You only really hear it once it's idling and you give a little gas, and until you're over about 30 mph or so, you really don't hear it. but definitely sounds like something in engine. Well today, i'm driving to the mall, and i my A/C wasn't blowing cold while stopped at a red light. i look and the gauge that shows the battery level, is lower than normal. I turn off the AC and then can smell coolant. I pull over and it looks like coolant has came out of the place you add water / coolant to the vehicle. Any ideas?

 

Your D is overheating or it may have air in the system in which you may need to purge it out.

Is the temp gauge normal? If so, you may need to take it to someone to check the temp switch to confirm.

Check for blockages on the A/C coil, take it to a car wash and power wash the A/C coil if there is alot of dead debris stuck in it.

 

it emptied almost all the water out of it. After i let it cool for a while, then refilled it with coolant, i let it idle for a few... then after turning off, i see water dripping but can't determine where it's coming from. Any ideas on the noisefrom the engine?

 

This noise may be the water pump. It may be the source of your leak and why your antifreeze is boiling over. I would have the entire cooling system inspected. Check the stat, radiator, fan clutch, etc.

 

do you think that could cause the battery gauge to be acting up?
