I want to put a lower tempurature fan switch in my camaro. It has the L03 engine. I am thinking on at 200, off at 185. What you you guys recomend? Also, which switch would you recommend, the only ones I have seen is the JET GM fan switch, and the Hypertec Cooling fan switch. I have read the tech article on this, but it seems that it was geared towards the dual fan, TPI engines, not my lowly TBI...Any input is great!

 

You may want to consider using an adjustable fan switch - they are available from Pep Boys & less expensive than the Hypertech fixed temperature fan control switch. Set the turn on point to approximately 25 degrees higher than your thermostat rating & set the turn off point about 18 degrees lower than the turn on point, although the hysteresis is fixed on the adjustable temperature fan control switch, so you will only be able to adjust the turn on point.

 

I will have to look into it. I normally go to either AutoZone or NAPA, both are really close. I dont normally go to pep boys, its a little further away, so I dint know about thiers. Thank you
