Question about 1991 Lexus LS 400
Would have repaced the thermastadt. most commen cause of those fans not turning on because thr thermostadt is not letting the hot water flow into the radeattor .by passing the wiring and relays can only lead to bigger problems , but you have proven your fans work. water just drizled out of the block cause you had no water in the house to the pump ( no water to pump) thermostadts, temp sensors or temp sending unit .simple check for themostadt fill up with all houses attached with rad cap off run engine fill rad as needed keep feeling top hose to radiator it should get hot all of the sudden thats your thermostadt opening( working) go to next step check sensors or sending unit. realy best if you get a haynes or chilton at the half priced book store or auto parts storeand go to trouble shooting for over heating
