Easy. My high temp readout problem is fixed - not sits at 80-85 like it should.

Did not drain coolant - just be ready and a little coolant drips out, but not a geyser. I did not spill enough coolant to see a difference in level in my expansion tank. All you need is a 19mm wrench.

So as previous posters said, just be quick. And watch out for the sharp edges on the injector hard lines!

Good luck,
dd
