the fan cuts off? or, does the fan continue blowing but the temperature is not hot? (why the heater in July ?)

Really doesn't matter since Gates kits are absolute trash. GD

You (or Chilton's) are over complicating this - focus entirely on the timing marks available to you that makes this *really really easy* and ignore everything else. Throw away the Chilton's manual (the time spent getting it, turning the pages is life wasted and they're a liability as you can see here), forget the phrase "TDC" for this job, put the camera/cell phone away and use the marks on the crank sprocket and cam sprockets: This is so, so, so, so easy - from where you are right now: 1. Line up crank mark 2. Remove belt 3. Line up cam marks 4. Install belt Done *If you're uncertain which marks to use - just google it and do an image search. I've never done it but I can guarantee there's about 10 zillion hits. Steps 1-4 I can do from start to finish including all the serpentine belt, timing cover removal in 45 minutes. Add a little for a first timer and it still probably doesn't take much longer than you've spent looking at Chilton's and taking pictures. Focus entirely on the marks and just get them to line up before you install the belt. For that matter instructions on doing the belt are everywhere as well. Once you install the belt - if the marks don't line up - wash-rinse-repeat and try again. I don't install the lower passengers side timing pulley until the belt is installed, it can be installed after the belt is on.

+1 Both compressors have roughly the same internal volume for moving freon, but the Lexus has a variable displacement compressor where the old school Brat compressor is a fixed displacement compressor so it's pumping full tilt all the time (unless the pressure switch shuts it off). The variable displacement may be mechanical or ECU controlled and is based off system pressures, flow and temp to yield acceptable cooling with minimal load on the engine to keep your MPGs up. Add to that, as you stated, the cabin size difference (Lexus being 2-3x the volume of a Brat) and the fact that R134 does not coll as well as R12 and there you have it. Your Lexus may also be having issues. Low charge, sticky temp door, plugged or stuck orifice/TXV or a cooling fan or condensor air flow issue. Give me old school AC any day.

I was told about a week ago by my glass installer that he can't get front seals anymore and the coupe rear window seals haven't been around for years. What gives?

If we could add EA81 Hatch rear glass I would be into that. If possible
