Hi Guys.
Both of my 1997 2.2 5SFE fans run constantly, even after turning the ignition to "On" in the morning, but not starting the engine. A quick search here suggests the problem is the Engine Coolant Temperature Switch, located at the bottom rear of the radiator. Before draining my coolant, I thought that if this is the problem, disconnecting the wire from old and connecting it to the new without installing it into the radiator should keep the fans off with a cold engine (or just turning the ignition to ON without starting a cold engine). Does that sound about right to anyone? Also, does this look like the right part: http://shop.advanceautoparts.com/webapp/wc...bwd_18970379-p# It looks right to me, but Advance Auto has given me the wrong parts before.... Oh Yeah! Do the threads need Teflon tape, or any other type of sealant? TIA!!! |

Your fans were most likely hardwired into the ignition switch at one point then, or perhaps there's a bad relay.
