Once downside of the bottom hose location is you may need a different sensor / switch if the one you have isn't adjustable. You may want to switch on fans at a lower temperature if you're reading it from the water pump inlet temperature / lower hose.

ERA uses the bottom hose method. The thermo-switch is pretty low, at 75C, but the fan seldom comes on except when the car is stationary. |
