i cant figure out why the coolant runs completely out about every 2-3 weeks. I have no leaks, the radiator is completely full and all of my hoses are like new, my oil level stays level and is always gold. i let the car run for about 8 min. just a while ago and i notices that there was condensation on the inside of my exhaust looking in from the exhaust tip i dunno if that has to do with anything, but it never leaked out just condensation. the car runs perfect im stumped!

can anyone help me out?

 

Condensation in exhaust is natural. Comes from the gasoline you use...

Get the motor to normal temp, then have someone throttle it up to red line, do you see white smoke?

 

no black or white smoke

 

What coolent are you using?

 

zerex, something my parents bought

 

anyone know what the problem could be? could it possably be the coolant im useing?

 

bump goin to work,

 

you could have a small crack in your head gasket, or block. do a compression, and leak down test.

 

how is the temperature of your car. Is it normal or over heating?

 

its runs below half way on the temp guage, never overheats even when i drive it hard for along time.

also the first time i noticed it was empty it wasnt overheating and it was probibly empty for at least 3 weeks.

 

can anyone help??

 

how does your exhaust smell. If it has a sweet smell to it you defently got an internal colant leak. I think the brand that you are using only makes Dexcool colant (orange stuff) that GM uses in their cars, we are suposed to use the green stuff. Check on that.

no sweet smell and im useing green coolant. could my parents have possably mixed it wrong or something? because they have it in a pre mixed jug.

 

could be that too
but if it was not mixed it wouldn't really cool your motor, that's what water is in there for. Check your oil see if it's not watery. I smell a bad headgasket or even worse a bad head if you say that there are no leaks outside the motor.

 

well im almost 100% the coolant is mixed correctly, the oil seams fine although i just changed it like 200 miles ago. is there any way i can tell if there is a bad headgasket or something

 

you can take off your head.....

 

is there anything else that this could be?

 

iss your passenger side floor pan wet? could be a cracked heater core. basically the heating/cooling system goes liek this upper lower rad hoses, iacv, heater core, that stupid *** huge tube in the back of the motor that usually gets a bad O ring or something. also the bottom of the TB there is a few fittings, jsut double check those things. hose your motor off with some engine brite or something to make sure you get it 100% clean, then run it, a few days see if there are any discolored spots.

 

check your compression too.

Is that the stuff that gm uses? If it is that stuff is known to gell up.

no wetness, all my hoses are perfect everything is like new. and i would know if my car was leaking because my garage floor is perfect and my parents tell me anytime my car leaks because they go scrub it off the floor.

could it be my rad. cap? could it be bad?

 

hmm bet its your water pump leaking while your driving its obviously a small leak , u had this on my vx i had in my sedan , never saw the leak but knew it was there , also a great time to replace the timing belt , replace the water pump and im 99% you should be fine if you dont have any visable leaks , other wise you may have a slightly blown head gasket , perfect place to start at though .

 

i had my water pump and timeing belt changed less than 1000 miles ago

 

didi the problem start happening after that?

I think this is most likely your problem area...
