Here are some part # for the thermal switch that turns the fan on a little earlier than stock: 1- BORG-WARNER TFS-545,
2-WELLS-SW537 ,3-Nissan sentra 1988
I am using the Nissan one but it is $65 from the dealer Vs the others I heard are ~$20.00 from any auto store, you can just ask for the Nissan one and they will give you the correct one.
When I first bought my 2003 ~ November in CA the bike was overheating badly if I get stuck in traffic, so I bought the Nissan one and since then the bike never overheated even in very heavy traffic ( but I usually never get stuck because lane splitting is LEGAL here
When connecting the thermal switch do not worry about polarity here is why, the body of the switch contacting the metal of the engine is the -ve, and the two terminals of the switch are just an interruption of the flow of the +ve , ask at any auto parts store which sealer to use for this application and they will recommend one.
Its also a good thing to flush the cooling system if you haven't in the past year or if your bike was stored for winter, It was recommended by people who know to use
Toyota factory red coolant, just get it from the dealer $23, its made specifically for aluminum radiators and does not contain silicates the damage the water pump seals. its concentrated so mix 50/50 with distilled water.
I used it and my cooling system is super clean!
