well, since all you guys can tell from the topic, my car is messed up, but i am wondering when the radiator fan suppose to come on? after you start the car?
when i drive around 110-120km mark, the engine doesnt over heat, even tho i drove 2 hours straight, but when i pass 120, it goes fast towards the red line.
would it be the fan thats not working, thats my first guess, and i dont know how to test it. so any suggestions at all?? thx, HT!

 

take a peice of wire and connect the 2 wires that go to the switch on the thermostat just plug one end of the wire into each pin should be 2 of them if the fan dont come on with the car started theres a issue with the wiring if it does its the switch my buddys car is running a 90 integra ls which dosent have that switch so we cut the connector off and twisted the wires fan just stays on while the car is started but shuts off when you turn the car off easy fix

 

if this dont work take a peice of wire and run it directly from the battery to the positive on the fan if it turns on the fan is ok heres a ??? what engine you running and what radiator

 

stock d15b and oem rad

 

ok, the fan is working when i tried the battery to the fan, but from thermo to the fan isnt working... which wire from radiator, should i hook it up to the thermostat if i dont want to use the relay anymore?

 

I'd keep the relay, youd probably need a new fan switch and/or ECT sensor for things to work right. Otherwise Id run a toggle siwtch to the cab and toggle the relay and fan on and off as I please.

 

so you tried the trick where you cross the 2 wires at the thermosat housing and the fan turns on ?????

 

yeah i tried that, but it didnt work... or do i have to wait for abit for the switch to comeon

 

if you crossed the wires and the fan didnt come on you got an issue with the relay saying that you hardwired the fan and it came on
