jdm swap now runs hot

nx2000racer · 07-08-2004, 12:18 AM

I just finished the swap and drove it, the engine seems to be extreemly hot.

The gauge says its right in the middle, i swapped over the sensor for the gauge.

I took off the coolant lines going to the heater core, since there is no blower motor, i just ran a short line for the 2 metal ends.

Any idea why it would seem extreemly hot but read in the middle?

mine seems to be pretty hot too, same thing. but it has run fine for a while now so i don't worry about it.

I don't know if you did this, but let me ask you anyway:

1) Did you change the water pump?

2) How about the thermostat?

I would say the motor is the running fine if your guage is reading correct, other than that i would say the theromostat.

thermostat, water pump or the system isn't bled properly.

the water pump and t-stat are both new, i dont think i got all the air out.

Well, I think you are right. My car ran around 230 all the time and i was shocked to find out that after bleeding the system some moron didn't fill the radiator back up! Once I added water (almost a gallon of it) car has been perfect. I run at around 158-163 on the highway and around 190 in bumper to bumper traffic.

Do ya have access to a consult or nprobe to see what temps the ECU is seeing? Nissan gauges arn't the most accurat (sp) things out there.
