Pretty slick and well done. Still a hell of a lot of work. Please tell me you HAD to replace your heater core on one of your rides and this was not simply done for two reasons.

1. You were bored after making a prototye tool and mowing down a bunch of soybeans and said, Sleep who needs sleep?

2. You simply love a challenge.

Yes...had antifreeze on passenger side carpet and foggy windows. But also item #1 and item #2 above. That darn tool erases Codes so easily by just holding button (turn key on) until associated Code flashes and then release for 3 seconds and then press button one more time....DONE.

Since I am under the passenger side Hush Panel with carpet removed I disconnected and reconnected the INFL REST yellow connector a few times to make sure there is a good connection to the right side Accelerometers on the frame rail (Just in case).

Oh....and I have been under the Passenger side Before on another ZR1 monkeying with the CDM.....I say monkeying because that is a son-of-a-gun also

There are a few notes added in the Post #23 above........
I am replacing the leaking Heater Core with a New Copper/Brass Heater Core.

OK.....found out something very interesting.......which requires an experiment.

Replacing the Heater Core.

The Top of the Heater Outer Housing (the one that is removed) has the top dual conduits for two vents attached to the Heater Core Outer Housing by two rivets (defrost and vent into passenger side just below glove box). Those two Conduits (one forward to left and one rearward to right) actually stick out interfering with the removal and installation of the Heater Core Outer Housing. You can get the Outer Housing removed by wiggling and bending the plastic Heater Housing but it is difficult because of the two conduits on top attached to that housing by two rivets. the top Dual Conduits for the two vents were attached to Heater plastic hoses (defrost and vent into passenger side just below glove box) which the two plastic hoses could be disconnected allowing removal of the Heater Core Housing with this dual top conduit attached. Those two Heater Plastic Hoses would be almost impossible to re-install after the Heater Core Housing is positioned and wiggled back into position having to connect the two plastic hoses after the Heater Core Housing is in place.

But.......I solved the problem



This could be a major improvement to the Heater Core Housing Replacement issue which now is extremely difficult without pulling the dash.

The Details are described in Item #1 and Item #2 Replacing the Heater Core and Heater Hose Connection
