Ok, so I replaced my water pump and thermostat yesterday. Let it sit overnight so sealant would be good and dry for today. Just went out and added 2 gallons of distilled water just to check for leaks. NO LEAKS! Started and ran the car at idle for about 15 minutes with the cabin heater turned up full blast and temp dials on both sides turned up all the way. Temperature gauge got up to the normal range (about half way) but the air blowing in the cabin did not feel warm. I'm in a garage, about 45 degrees out side, hood up on car with the cowl off. Windows of the car are both down. I never saw the radiator fan come on. Why isn't the air blowing warmer inside the cabin?
I plan to drain out some of the water and add Zerex G-05 antifreeze to a final mixture of 50/50. Once I'm sure I have no leaks but that looks good so far.
I should note that I had good heat blowing in the cabin before.
