3.2L Engines

1. Verify engine coolant level. If low, fill cooling system as described on page 7-13 of the service manual and proceed with next step.

2. Check the left heater outlet duct under the I/P to verify that its outlets are oriented down toward the customers foot area. If not, remove the duct and re-orient so that it is. Proceed with next step.

3. Fully warm up the vehicle by allowing the engine to run at 1500-2000 RPM for 15-20 minutes to verify if the low/no heat condition can be duplicated. This should also serve to de-aerate the cooling system.

4. Connect DRB III and verify that the coolant temperature is above 180°F (82°C). If coolant level is okay but engine temperature remains low, see section "Core Sand Contamination," found.

5. If coolant temperature is above 180°F (82°C), but heater performance continues to be poor, perform HVAC self diagnostic on page 24-8 of the service manual. If fault codes are found refer to the appropriate service manual section to correct the fault and re-test.

6. If condition can not be duplicated, see section "Core Sand Contamination," found.
