Well i dont think its a head gasket kuz id have oil in my antifreeze and antifreeze in my oil and i dont.. I just sucked all the antifreeze outta the overflow till the full line and put it in the radiator like its supposed to do on its own.. now that whistle i had after it heats up goes away and sounds like a clonking noise.. i cant win

 

Seems like the radiator was working right for a few days but i just checked and theres still not any antifreeze in the top of the radiator. Think it might be the thermostat ?

 

So your radiator is empty? How has your car not overheated yet? The radiator holds at least 3/4 of gal of coolant. The reservoir is not even a quart.

If your thermostat is stuck closed then it wont take in the hot coolant(upper pipe) ...it should actually suck/vacuum from the reservoir to compensate and not return it back.

 

Idk if its emptey but its def not full to the top kuz theres no antifreeze on top of the radiator when you open it.... and idk thats whats got me so confused the gauge stays normal and it doesnt seem to get that hot... and the overflow is full

 

there definitely should be fluid at top of radiator visible.

 

Check where the cap seals to the radiator for gouges and scratches. If none then try a new cap. I've had caps bad out of the packaging. If that doesn't fix it then I'd suspect a blown head gasket pushing fluid to the jug faster than the radiator can suck it back. Once the jug is full it goes overboard.

 

I know the radiator should always be toped off.. They put a new cap on it at the speed shop. but i guess i might have to get another. what psi cap do i need or bar

 

16 psi

 

the one they put on says 1.1

 

1.1 bar = 16psi

 

Another thing to check is the hose between the radiator and jug. If that isn't a tight fit all the radiator will suck is air.

 

alright thanks so thats right then

 

i checked them all real quick when it first started happeing but ill check it again. and its only sometimes that there isnt any fluid like i took it to work today and checked it after work and there was at the top and i just checked it now and its not again..

 

Try this- With the engine cool take the radiator cap off then start it. Once it reaches operating temp keep filling it until its topped off. Turn on the heat too...or the AC. It sounds like you dont have enough anitfreeze in it. Unfortunately it also sounds like that dogged your car out while it was in their hands. Do you have a manual boost controller in your car?

 

I think its full kuz it overflows sometimes.. but no i dont have any boost controller
