Hey Scotty I recently changed the coolant on my 98 GMC Sonoma. It used to blow great heat, but the coolant was way past due, so I replaced it. I realized that it doesn’t heat as much as before, no overheating either. Any ideas? Thanks. Love the videos

odds are you still have air in the system, heaters are the highest points and air gets stuck in there THEN the heat won't work fully as it needs hot water, not hot air to work
