Okay so I have a 1997 240sx with a KA24DE.
I was driving my car and it was driving fine and all then out of nowhere it starts to overheat. So first thing I do is check the upper rad hose, it was warm like it should be. The lower hose was cold. So I changed the thermostat and filled it back up with coolant etc. Then it overheats again.
So I brought it to a local shop and they said the radiator was cracked. Bought a new radiator and installed it then refilled with coolant and bled the air out. The bitch overheated AGAIN.
So I have a new radiator and new thermostat and it still overheats. The water pump is working correctly to my knowledge because with the cap off the radiator you can see the coolant flowing.
Then it overheats on me again and I pull over and knock on this random guys door for some water so I could drive it back home which was only like a minute away if that. Well it just so happens that he use to own a mechanic shop and he helps me bleed the system by opening the screw and pouring water in until the bubbles come and then stop.
After he did that my car ran fine for about 2 days then it overheated AGAIN. I couldnt look around or anything so I just waited and I added more coolant to make it back home. It seems like adding more coolant helps but it still overheats at least 2 days later.
So Im guessing theres a small leak somewhere but I have no idea where it is. Also 2 of the bolts that hold the thermostat housing in are broken off like someone was tightening them down and just overtightened and the head of the bolt broke off. The other bolt is fine though. Could it be leaking from there?
But recently is where I'm lost. Its been doing this for about a week now and each time it overheats I pull over and let the car cool down for a little bit and add more coolant and its fine for another 2 days.
Well today I was leaving my girlfriends and it started overheating. I pulled over and had my mom pick me up and went back to the car and added coolant and drove it home. It did fine on the way home.
I get home and take a shower and get ready to leave and I get in my car and get about halfway down my road and it starts to overheat pretty quick. I turn around and get back in the driveway and open up the coolant overflow and there is liquid in there but it is NOT the color of coolant and steam is coming from the overflow tank as well.
How do I know if my block is cracked or what? Also when I pulled over after leaving my girlfriends I noticed coolant coming from the middle-ish of the engine. I checked the thermostat housing to see if it was leaking from there but it wasn't really. Also the lower hose had some coolant on it as well.
Any ideas? Any at all? If i cant fix the problem soon im just gonna sell the car. This is fucking ridiculous and its been effecting my daily life cuz this is the only car I have and i am not made of money.
