My coolant keep coming out of the reservoir screw on cap. Everytime I start the engine the reservoir coolant level goes from normal and keep going up until it starts pouring from the cap.also having no heat from vents at all after this started.

Blown head gasket can force air into the system.
Don't drive it like that.
@carlos
But it's not giving me any signs of that no oil and coolant mixing, no white smoke from exaust
Sometimes they will only (or mostly) force exhaust gases into the coolant without producing much smoke at first.

@carlos
Is it normal that it happend randomly and everything was working fine right before it did that
@carlos
Everything is fine until till it gets to operation temp for about 20 mins then it starts over flowing the reservoir
Yes. Sometimes a gasket just goes all at once.
You will have to verify though. A blocked radiator or other issue could mimic the problem.
@carlos i find it strange the the motor doesnt overheat at all. But it has zero heat from ventseven at operating temp when it did before this happend
@carlos
I ran it for a while yesterday and the needle stayed right in the middle. I have the heat setting all the way up and still nothing
Had an old dodge that did the same with a head gasket leak. It held enough fluid to not overheat, and when I shut off the car it would gurgle loudly and overflow.
@carlos
You think a sealer would help since it's in its beginning stages
I wouldn't know. It would be worth a try.
Maybe re-post your question and ask about sealers.
There are plenty of experts out there.
@carlos
Uh alright thanks for your help
Sure it can happen that fast. Certainly sounds like a head gasket. How many miles on the engine?
@porkchophill
186k would a sealer work since its barely starting
@porkchophill
To fail
My coolant reservoir keeps getting too full like when cold starts at normal levels be then after all warmed up it rises and starts pouring out of the cap
Plz someone help
