RE: 91 Nissan Maxima Rad Fans?
.... fans only come on when ...
If so, maybe belt slack, air in system (bleed), pump blades corroded, rad blocked
On moderate weather and no A/C on, the fans will not normally start, maybe on long idle. Fans do have 2 speeds. Check out http://www.cardomain.com/ride/748507/7 & page 8
Test disconnect EGRC temp sensor connector: idle rpm raises, both fans at max speed. Now u know that ECU got the signal, energized all 3 fan relays, fans do their job...
