About 2 weeks ago my car overheated because of a hole in the radiator hose. After replacing it my car ran fine until last night. After putting gas and starting it it was "running weird’ as in the noise was not the same. The check engine light was on too. I went and checked the check engine code and it said that cylinder 2 has misfired.
Now my car runs really harsh whenever you turn it on. It seems like it is about to die/turn off. It has turned off twice on me while on a stop sign and clearly it’s not as powerful as before. After reaching a certain temperature( little bit below the middle, that’s where it usually stays) the car will run normal again. It accelerates nice and the sound is smother like before. Also I have noticed that when I turn it on a “sloosh” sound is heard.
My suspicions are that is a blown (or damaged) head gasket. I opened up the radiator cap and there was bubbling and I was told this was one way to check if the head gasket is blown.
The coolant level seemed a little bit low in the radiator but the coolant reservoir had a decent amount (around 70-80%.) I put in some more and the coolant reservoir ended up “spilling it out”. It has a little hole in the cap which spurts it out whenever there might be too much(?)
Has anyone experienced the same issues before with their car? Would a sealant work temporarily (around 2 months.) I drive only a small distance everyday, would it still be okay to drive?
In addition the temperature sensor had something wrong with it (there was a code for that too) Could that be another reason why? My car doesn’t overheat anymore but I am not sure if I should trust my temp gauge anymore.
