For your information- here's a little solution to a dilemma I was having with the Aspire when I was having overheating issues. I wanted to get a coolant switch to turn on the radiator fan sooner than the factory's set 207 degrees and saw some 3/8" NPT switches on ebay. This might be easy with a Festy because it has a separate coolant temp sensor and coolant temp switches, so this switch threads right in with the threads already on it- but the OE circuit on the Aspire is switched by the ECM computer and not a switch on the block or water inlet.
I had seen these adapters also from china- (The blue alloy piece in the photos) but they are apparently all drilled 1/8 " NPT -the sensor size and not 3/8NPT- the switches larger size.
I still got a cheap switch anyway for several dollars and the adapter to add to the upper hose if I ever need it. I noticed the switch though had an end to it that looked as if it almost fit the smaller 1/8" NPT drilling. In fact VERY much like all it was missing was threading held back'
So I got a 1/8"NPT die from China for 4 or 5 dollars- and sure enough- tonight I used that die to thread that shaft, which now screws into the adapter-
All I needed was vice grips and a crescent wrench and a little oil to work the switch back and forth a bit through the die and not difficult at all though I got it just a little crooked- it still threads onto the adapter really well.
so I can still have the sensor in the block to run the gauge, but I can run a new circuit to the adapter if I want to run the fann temp lower
pretty cool, eh?
My pictures are all post-die-ing, and so that's why the die looks so gunked up.
