95 Accord LX, At the beginning of the summer i disconected the temp cable that runs from the junction under the dash thru the firewall to the heater hose because it was not closing the valve all the way ( letting hot water into the heater core). now i connected it back up but does not get full hot. My question is, is there any mod to help this such as a vacum system like the newer one's?
