Coolant overflow

[e34_spangler]

What problems cause coolant to come out of the overflow?

[Cabriolet]

you need to bleed the air out of your system. (usual issue)
or you have a blown HG/head

Ok no its a head gasket that's what I figured

[e34_spangler]

Does a leaking headgasket stay constant on how much will come out of the overflow? Cause it seems to vary

Not necessarily. This is typically indicative of the HG. Good luck!

well see i wanna say head gasket but ive been tracking it like the past 2 days i had nothing come out coolant stayed at the same level but then today i think i lost a little tiny bit but if it was a headgasket it would leak all the time wouldnt it?

A minor head gasket leak won't always be consistent . It may depend on how far the car is driven, how fast, and what the ambient temperature is. But if you are seeing a loss of coolant with no apparent leaks, the head gasket becomes the primary suspect.

when is it coming out? is it when your car is running and hot with the cap off?

[e34_spangler]

No its just random while I'm driving and its not much at all very very little and some days none at all what if I just capped the overflow?

Before anything, start with pressure testing your radiator cap! It can fail to hold pressure and allow coolant to spill out prematurely.

Replaced that with a used one from a buddy who was parting
