Kinda of a weird and hard problem to diagnose, but I would start with something simple like purging the cooling system for air. I would also pressure test the system.
Guess it could be cause I never installed the air dams back into my car when I swapped the motor.. I think I'll put those back on and see if it helps any..nismojunkie said:well with the fact that your going 70mph that means your rpm are kinda up there.
and the fans dont do that much at those speeds.
the problem alot of times is the air dam under your car like a little black plastic peice hanging down.
its job is to push air up to your eninge. so if you lowered your car and broke it off or took it off that would be ot.
or one of your hoses are clogged a little....but not too much to matter at lower speeds.
nope.BolognaBlake said:it's possible. What kind of temps are we looking at? How high does it get.
It really sounds like a old/clogged radiator to me.

when i first got my car it had no fan at all and stayed cool so just check the sensor and
use a process of elimination .
