Replacing Fan Switch
Located the fan switch by cylinders 6 & 8. The big question is how do you get it out? Fortunately & unfortunately I have gorrila hands. The sensor is located behind the sparkplug wires standoff which is partially blocked by a piece of tubing with a thermo wrap (don't know how else to describe the pieces). And of course will throw in the oil dip stick tube. Not complaining though. Anyway does this all need to be removed? I can get the wrench on it but can't turn it in either direction with all the obstuction. Maybe this is better suitted for a mechanic. What do ya'll think???

Unless it's an '85 or below, you're looking at the gage sender. Aux fan switch - through '89 - is between 1 and 3. After that, the PCM controls both fans based on Coolant Temp or A/C signal so there isn't any switch (nor will it have one on the earlier Years without the aux fan option). Test either by disconnecting the harness and grounding it to the block. If the aux fan comes on, it's the switch. If the gage reads 300 degrees, it's the sender. Remove with a socket, but you might drain some of the coolant first. Before careful with the connector as they're rather fragile after a number of Years. I've found replacement Weatherpak's at Pep Boys. You don't want any resistance in this circuit (fan switch or gage sender), so be sure to solder any splices that you make (or I just crush what's left of the old one and insert the lead into the new connector).
