Solving ‘No Heat’ Problems

This video covers the basics that I’ve typed out for years. I hope it helps you if your vehicle doesn’t have heat.

Nice vid.

If the gauge takes ages to come up to temp. the stat would be the first place i’d look as you suggested. Although if you don’t have a fancy thermometer simply start the car from cold and keep your hand on the upper hose. if it starts to get warm in a couple of minutes then you know your stat is stuck open. 🙂

Why do thermostats fail?

I’ve never had one fail since owning my first car in 1966.

So I’ve never inspected a fail one.

They use a bimetallic springs to work. It’s metal. After a while it will fatigue and fail. Kind of a wear part if you will.

This was a great segment. This week my car, 2000 Buick Regal 3.8 non supercharged with 305,xxx miles, had the no heat problem. Started with the basics, checking fluid, bleeding system, check hvac fuses, etc… Still no heat. Back flushed the heater core and what looked and felt like pea gravel came out. I filled the heater core with water and flushed out with air probably around 15 times. Instead of using electrical tape to make a tight connection I used a piece of fuel line. It fit very tight and never had it come out of the heater core line.

Eric the car guy, you rock!!
