Thank you for help in the past!  Now again facing some challenges!

When the temperature gauge needle moves beyond the middle point, I noticed that the radiator fans are not running. When stop or Key OFF and then ON after few seconds then the radiator fan start running. I am assuming that radiator fan thermo/ radiator switch or fan radiator relays are not malfunctioning.

Firstly, I tried to the relays (4pin,5pin). There are two 4pins relay, 1) the 4 pins relay (90987-02004) tested by supplying 12v power and I hear the click sound and tested the multimeter-continuity of the other two legs, I sound beep on multimeter. while 2) the 4 pins relay (90987-03001) did make the click sound, and when tested with the other two legs shows continuity on multimeter-continuity. 

Secondly, The 5 Pins relay (90987-04002) (2pins on onside and 3 pins on other side. I am not sure how to test this type of relay. I tried to search on google but help on text or video for specifically this model of relay. I tested randomly and found that in set of 3 pins side between Pin 1 and Pin 2, there is resistance (de-energized) and 2pins set on other side, lets says between pin 4 and pin5, there is no continuity. As I energized (12v at pin 1 and ground at pin 3), I hear click sound, there is continuity between pin4 and pin5.  I hope it means its functioning though there is not set standard operational specifications to compare. I tested the similar way to all the relays I pulled out and fuses are good. I put all the relays and fuses back.

But the same problem as I mentioned earlier, fan does not start when temperature is increasing beyond limit. however, when I start A/C, both the radiator fans start.   

Same thing is repeated as I mentioned earlier. I do have oil Leake from sides of distributor, but it was there before for couple of years. This time I going to fix with new distributor because last mechanic said that the inner seal he can't fix so I have to go for new distributor. However, I am not sure is this part of the overheating cause?  Also, attach is picture of engine area, if anybody can help me locate radiator fan switch in the picture. thanks

Any help! Thanks so much
