OK, I have an 88 MJ and 90 XJ. I converted both to an open cooling system with post-HO parts. I had heard that doing this would increase the heat in my cab. So...I've NEVER had any problem with the XJ..no heater valve...straight thru the core...no unwanted heat thru the vents.
The MJ however is hotter than %&@# w/o the heater valve. On this and other forums I've previously spewed that running the hoses straight thru the core WON'T affect the HVAC system. My experience now is - NOT!
...any thoughts why the two Jeeps are different? I get hot heat with the HVAC turned to OFF. I bought the valve, but I don't want to ruin it in a puddle of coolant unless I investigate.
