another heater issue
I have a heat output issue. Not very much heat at all. Here are my temp readings:
Heater set at 90d Coolant temp 198d per DIC gauge right in the middle upper rad hose 188d lower hose 167d heater hose 208d (not sure which is inlet or outlet) heater hose 270d drivers dash vent 83d passenger vent 87d Inside temps were taken with a good cooking thermometer. Engine temps with a laser infared temp gun. The heater hose at 270d surprised me how high it is. New OEM AC 195d thermostat installed yesterday. Is this a plugged heater core? Pat Callaghan |
Did you say 270d for a heater hose?

Check the temp of BOTH HEATER CORE HOSES..... if nearly the same the core is not the problem, sounds like a temp actuator.......
If one hose is much hotter than the other, then the core is plugged..... Is this a dual temp system? |

Are the mode and inlet actuators working?
Problems in the HVAC should set "B" codes.....not all scanners read B codes..... |
