Hi all!
As the title suggests, my '92 J-Spec SPI's temperature gauge went into the red over perhaps 10 minutes of heavy crawling traffic. I couldn't tell if the auxiliary fan came on but it sounded like it didn't. So here's what I did to test
1. I bridged the 2 spade connectors from the temperature sensor switch in the radiator with the engine running, auxillary fan came on. I suppose this the auxiliary fan circuit's / fuses etc. are good?
2. I tested the cooling fan relay by measuring the resistance across both pairs of terminals, one 80+ ohms and the other no resistance. Seems to check out.
Any suggestions on where I should look? Does the radiator sensor switch usually fail, it's only been a year since i bought the new minispares radiator that came with it? I apologize but I'm really not sure if the auxiliary fan came on and it still over heated, or if the auxiliary failed to come on at all.
Thanks!!
Best,
