Hello everyone now that the 68RR is running again, hopefully this is the last gremlin. I took it for a ride today and I noticed that the heater hoses and top radiator hose are quite hot compared to the warm bottom hose. I replaced both the water pump and thermostat about a year ago but never got to drive it due to family issues. Just for giggles I dropped the antifreeze and replaced it. When I started it today, I left the radiator cap off and it did suck down additional coolant. I let it idle 10 minutes , I capped it, and took it for a ride. Same scenario. What do you folks think? Why such the temp difference in the 4 hoses? stuck thermostat? clogged heater core even though their is heat in the car? defective water pump? Or is their still air in the system? And lastly the temp gauge inside the reads about half way for a 10 minute ride at 50MPH Thanks for your help.
