Thanks DennisMik for the accurate info regarding the fan motors! I guess i owe ya a couple shots of Japanese whiskey!?

Should I buy Nissan oem cap? buy a Mishimoto radiator or put in a thermostat housing without the thermostat? Plus I have a #3 injector out, does that increase the heating, I don't think so. also after putting in Zerex coolant, with the car jack up very high for 4 hrs it got hot, but only at 1500 rpms, but had tons no heat now at all. Sorry for this epic mesg. Just perplexed and angry, literally almost put the AR 15 on it today, just that mad. Also, oil not milky. 4 hrs jacked up never stopped bubbling. Used a modified no spill funnel. I you have a trick to open those 2 ****ing bleed holes please let me know. May I should do it, zero rust on this car. Going to wrap it up, wrote a damn article, if you think I should take it to the forum let me know,my poor FSM is in tatters.

I understand it, when it reaches this presser the cap at the very top opens slightly to suck in coolant from the overflow. I peeled of the paper on the 2 jap caps and don't see any difference, but it is slight I assume.I've done the dye test, nothing. No water dripping under the car.

All the caps except the red handle release cap are j/y caps,

Hi Dennis, glad your still above ground. Well I haven't talked to you in awhile, things have been going pretty good. Since I last talking to you I have put in both front quick struts, (geekparts 138.00 with shipping, 138.00 for one at advanced, geek with shipping was 138.00) Kyb. Also did right side lca 42.00 with shipping including the ball joint. left front drive axle from advance. Everything worked right with few problems.
however I get the same problem, coolant goes into the overflow tank but never returns to the radiator--part 1of 3
Now the problem, the ****ing problem I have been dealing with since I got the car. Overheating. Entire cooling system has been replaced. 2 leakdown tests, both good. 3 radiator caps, I have the one where you can lift the red handle, to release pressure, then from the j/y I have a maxima cap with japan writing and aI30 cap with just english and jap writing. So the system and cp is around 20psi ,
