Electric engine fan thermostat

Electric engine fan thermostat

Postby mchevalier [OP] » August 24th 2013, 1:52am

Hello all,
I recently installed an electric engine fan on my 01 Astro. Second one I've done it to. Better MPG and power on both.
For the fan thermostat I used a sensor pushed through the radiator. I would like to put the sensor in the coolant, the water outlet seams like a good place.
I'm trying to find a water outlet that will fit the 4.3 and have a threaded hole for a sensor. I've thought about drilling and threading the existing but the metal on those is not very thick. I've seen some for small blocks that come with a threaded hole I could put a brass plug in and thread that for the sensor, 8 x .75.
Or are there any unused plugged holes on the engine or manifold suitable for what I'm doing?

Doesn't that plan only work after the thermostat opens? At least that is how the setup I made from scratch for the LS1 Astro works.
