Check you coolant level, If vehicle has been run recently, wait until engine is cool before removing cap. Squeeze the radiator hose to check temperature, and for pressure in the system. If the hose is very firm, allow time to cool down. Place a rag over the cap and turn it to the first safety stop. Allow pressure to escape through the overflow tube. When the system stabilizes, remove the cap completely. POSSIBLE LOCATION OR CAUSE OF INSUFFICIENT HEAT Obstructed cowl air intake. Obstructed heater system outlets. Blend door not functioning properly. Low coolant level Air locked heater core or air in cooling system
