sonic113 Posted April 3, 2016 Share Posted April 3, 2016 Recently noticed my heater is not heating the inside of the car as quick as it used to from cold start. I was thinking to drain the system and renew coolant to see if it helps before looking at the thermostat. My coolant levil is at the Max Level, I know some people keep it between max and minium for expansion purposes or something , so would having this at the max effect the insdie heater? engine tempture seems to be heating as normal just the cabin heater taking a while to get hot air in. Thanks Quote Link to comment Share on other sites More sharing options...
