DaveT Posted March 3, 2017 Share Posted March 3, 2017 Have to measure the head temp with a real thermometer. The dash gauges are notoriously not calibrated. I have had more than one of each of the following: Normal temp reads as about 1/8th scale, 1/4 scale, 1/2 scale. By scale I mean where the red starts is full scale. They have on the other hand, been very consistent, so once I know where normal is for that car, I know it's normal. The heater may be not working well if the core is blocked, or if the blend doors are not working correctly. Check the temp of both of the heater hoses - better still, the pipes right where they come through the firewall, if you can sneak a sensor in there. Do this after a drive, put the heater on heat, with the fan on high, and on low. Link to comment Share on other sites More sharing options...
