hey everyone how you doing. well yesterday my car started to drip water off the top of the radiator reservoir and i checked the radiator and it wasnt full anymore but my temp gauge never went up.. i wanted to know wat can it be... please help

 

The title says the car overheats but the first post says it doesn't.

A common location for a radiator leak is the top front seam. Is that where you are losing coolant?

 

no it was from the radiator reservoir

 

Is the reservoir overflowing or actually leaking from a hole or crack in it?

 

it was over flowing in a boiling type

 

But the engine did not overheat by the reading on the temp gauge? Where does the needle normally rest on your temp gauge when the engine is warmed up?

 

That sounds headgaskety. Did it smell like exhaust or gas fumes at all?

 

no it didnt smell at all

 

How does your radiator cap look?

 

at about a 1/4 on the cold side

 

it looks good

 

Auto parts stores sell kits used to detect exhaust gases in the coolant.

 

But when you run it with the cap off you can see the coolant flowing?

 

it looks like if is not flowing

 

It's rare for the water pump to fail (except for leaks), so this is likely due to gas bubbles (possibly exhaust gas) trapped in the cooling system.

 

how do i fix that

 

You are not ready to fix anything yet because you are not sure what the problem is. There's a chance that the head gasket is blown, so do the test mentioned in post #12.

 

Also check for a defective (not opening) thermostat if there is no flow through the radiator when the car warms up. That could also explain coolant forced out throught the reservoir.

Other than that I'm tempted to say its more likely a blown headgasket forcing exhaust gasses into the cooling system (and coolant out). Get a block tester (NAPA) to test for exhaust gasses in the radiator. In order to properly use the tester you have to have the coolant level 1 inch below the radiator neck to make sure you only get air/gasses and not coolant to pass through the tester (it comes with detailed instructions).
