Heater Inspection

Heater core:

  • Leaks (before removing, check for leaks in passenger area, under carpet, on firewall cardboard, etc)
  • Flow (ensure it is not plugged). You can test similar to radiator blocked test (http://wiki.datsun1200.com/index.php/Radiator#Trouble_Diagnoses)
  • Clean out debris in exterior of core

Hoses: Check for cracks, overly soft hoses, tight clamps

Flow valve: ensure it opens & closes easily through entire range. Also check linkage for easy and complete movement (before taking apart)

Air ducts: Ensure they are clean and connected properly

Electrical: Ensure fan spins at both High & Low speed

Coolant Thermostat: Test
