One of the things I'm considering for simplification is to eliminate the heater control valve, so that coolant can flow from the thermostat housing through the heater core and back to the water pump unimpeded. In my limited research I see that some of the later models had the the control valve eliminated by design, but the rest of the HVAC system is also quite different for those years as well. I assume that somebody here has already tried to take the hoses from a later model and put them on a pre-97... Do the hoses work okay? Any problems come up with running coolant through the core all the time? Any gotcha issues?
