Coolant Levels Consistently Drop Dangerously Low
Please help!!
My coolant has been dropping at an insane rate, I just filled it to full last night. Since then I only drove to the gym and back. this is where i’m at coolant wise. It’s been a reoccurring problem for about 2 months now.
I did a little research and from what I gathered I saw that it could be the water pump and thermostat so yesterday I swapped them out for new ones. The problem persists. Side note I also replaced the reservoir last week thinking that would help.
My question is what could it be ?
A little background, this car has had no issue up until about 15k miles ago where I noticed a bit of a head gasket rattle on start up. So I put K-seal into my reservoir, after that no rattle. Now it’s just a minor rattle but nothing to be concerned about like before. Other than that the car runs fine. I’m just having this tricky issue that my coolant just disappears and leaves no trace.
Any help would be greatly appreciated.
