Messed up.!!!

[Stebo200]

Well ......

I have 93 240sx and its really messed up...i have changed the radiator cap..the temp sensor the water pump the thermostat and nothen seems to help but i think my radiator hoses might be crossed so i want to know if there is anybody out there with a 93 240sx that could tell me were the top hose is suppose to go and the bottom . It seems its not circulating very well and my bottom hose is always cold. When i stop driving and park it ...it seems it gets airborn cause it pushes air into my overflow..

If anybody can help me i would really be thankful...

Well on the motor, there are two ports for the coolant. The upper outlet port really close to the throttle body. That port is hooked up to the top radiator hose. The other inlet port for coolant is hooked up to the lower hose for the radiator. Sounds to me like you have a thermostat or a air pocket problem. I'd suggest replacing the thermostat and get rid of the air bubble.

I had a nasty air bubble in my 91. What I found out is that the air relief valve is above the level of the radiator cap. Therefore in order to release the air bubble to must jack up the front of the car so that the radiator cap is higher than the air relief valve. Unscrew the valve and watch for coolant t o start oozing out. Once you see that put the bolt back in and off you go. I had that same problem you have and this fixed it. Now I just gotta' get one of those lifts in my garage...
