I had been holding off to change out my heater T's because I wanted to do a Hot water kit and thought that it seemed reasonable to do both jobs at the same time. So I've been carrying a spare set with me just in case, even though the factory set still looked great. In any case, time came to install the Helton Hot water Kit, new T fittings, and all the associated hoses.
It only took me 15 minutes to get the old hoses off, as I have done these before and found a few tools that make light work of the job. In case it helps someone else, I used needle nose vice grips to move the clamps off the connections. Then I used a hose picker tool that I made from an old screwdriver to break the seal between the hoses and the pipe fittings (a bit of silicone spray helps on the stubborn ones). Then I used some needle nose hose pliers to twist and pull the hoses out.
All that said, my perfectionist slacker nature took a few hours to reinstall the new parts.
The old T fittings were actually in surprisingly decent shape and since they fit the factory hose sizes so well, I replaced them with the same OE quality parts, with the exception of the 2 hoses required to route coolant through the heat exchanger. I used the constant torque clamps on those hoses.
I noticed a couple of other things that I wanted to do along the way.
-It was helpful to have a small tray for parts and tools while working up under the hood. So I flipped the engine cover over and used that, which worked well. My paranoia of tipping the thing caused me to drill a hole in it that allows use of one of the mounting studs to keep it from moving much. This might come in handy again some time.
-The cycles of heat over time had caused some of the wire harness mounting loom and clips to become a bit brittle. So I replaced those that were broken or loose and decided to add some more protection from heat to the main harness loom. I wrapped it with a bit of header wrap and some gorilla tape to add a bit of heat shielding to the precious harness.
