There is no way to estimate cost until you know the exact case of the noise. See the dealer for a test drive so a tech can listen to it.

You have a bad PCV hose and/or a dirty IAC.Replace the hose and cleane the IAC and it should eliminate the problem. If you are at all handy, it's two bolts to remove it and it's easily accessible. Worth while to take it off and clean it. A can of carburetor cleaner and 5 minutes of your time will get the job done.

System should be around 1.25-1.75 lbs

This could be a number of things so I would recommend starting with the easiest of them first and that would be to carefully examine the coolant reservoir to make sure that it is not leaking and then check the radiator hoses and water pump (located on the left side of the vehicles engine if you are facing the windshield with the hood up) while the engine is running at normal operating temperature. Most of the time if there is a leak then you will be able to see it. If you are unable to spot a leak outside the vehicle, then you will want to check the passenger side floor board to see if it is damp, as the heater core is located on that side. If that is good then your vehicle may be consuming the coolant and burning it. This is a sign that you have either a bad head or a blown head gasket. If the head gasket is blown and the engine is consuming the coolant, then it should be smoking when it is running and you will be able to smell the antifreeze burning. I hope that you have found this information useful as that is my goal. Good luck and if you have any more questions, feel free to ask me.

it also happen to me on a mazda mpv 2000 for years i was adding anitifreeze i found out that the water pump was leaking just do it yourself easy change just pay $60 dollars for it. underneath the car theres a plastic shield the antifreeze will drip and stay there thats why you didn't noticed the leak.

Does anyone know the cylinder number locations??

Basicly just follow your nose on this ,remove the fan and cowlings if fitted then the top supports and i dont think their is any on the bottom it just lifts out but watch for the AC rad as it may be bolted to the main rad in some way shape or form ,when refitting fill with water and try it out if ok then a minimum of 50% antifreeze its also a anti corrosion .

if you can see the leak and there's no stress fractures around it you could get it plastic welded (soldering iron) you could also use a twin pack epoxy filler, just make sure you scratch up the plastic first with a medium/coarse sandpaper to improve adhesion
