I was recently given a 1999 Honda Civic Lx for free from a family member and its been my day to day vehicle for months. I wont lie, aside from keeping oil, gas, and all of the standard stuff like it I haven’t put very much work into it since I got it. Recently I noticed the car would start to run hot at low speeds and while sitting at traffic lights, stop signs, etc. When this would happen I would just throw some water in the radiator cap and the problem would be solved. For a few days at least. Today I was driving and did not notice that the temperature was getting pretty high. Not into the red, but getting close. When I saw this I immediately started looking for some where to pull over to put some water in. Before I could get stopped I heard a loud popping noise and the sound of water pouring out from somewhere underneath the car. The second this happened the temperature gauge went down for a few mins but then rapidly shot back up. I got stopped and started putting water in, though I assumed the damage had been done. Sure enough the water eventually started coming out of the bottom of the car. Seems like its coming out of the little crevices in the engine and not the hose or the radiator. Im assuming (or hoping, maybe) this is a blown head gasket and not something more serious. The car is now parked and not going anywhere until repairs are made. I’d just like some insight from someone with a better knowledge of automobiles than me because I know next to nothing.
Any feedback would be greatly appreciated! I apologize in advance for my serious lack of understanding this subject.
